4 POLYMER-BOUND CHEMICALS AND ADDITIVES pre-dispersed rubber chemicals and additives With, Rhein Chemie has set the industry standard for pre-dispersed rubber chemicals and additives. Selected raw materials and a specially designed elastomer binder (EPDM/EVA) ensure top dispersibility with excellent compatibility in most standard polymers. The binder system provides optimal dispersibility and long-lasting storage and transport stability at the same time. Free-flowing for easy handling allow more precise weighing and dosing, making automated, continuous processes feasible. The consistent quality of ready-mixed batches is crucial for a trouble-free process during subsequent production steps and overall improved product quality. Reject rates can be minimized and costly reworking processes avoided. is dust-free, meaning it keeps the work area clean and free of toxic chemical dusts, this being a prerequisite for the production of high-performance rubber parts, and not only in the automotive industry. For easy iden tification, selected grades have a specific color code. Geniplex-70, an activator for the sulfur-curing of EPDM and other diene rubbers that also provides activation for blowing agents, has an activating effect on accelerators. The processing safety of rubber compounds containing Geniplex-70 is increased, and curing improved. Thiurams and carbamates that form carcinogenic N-nitrosamines can be replaced by Geniplex-70 without any negative effects on processing safety or mechanical properties. Rhein Chemie s dithiophosphates are not only the additives of choice for N-nitrosamine-free curing, which is mandatory today for state-of-theart motor vehicles, they also provide versatile solutions to various problems, from improving reversion resistance to coping with dispersibi-lity and efficiency problems, thanks to their high solubility in all kinds of rubber. One such product is TP-50, a world-class product for the N-nitrosamine-free curing of EPDM extrudates: In combination with standard accelerators, TP-50 sets standards in achieving cost-efficiency in EPDM extrusion while keeping reject rates low. In particular, the considerably high solubility (up to 6 phr) provides high flexibility in a wide range of formulations. CLD-80 is a real multitalent: Invented by Rhein Chemie it is a sulfur donor. Unlike ordinary sulfur, CLD-80 ensures an extremely stable vulcanization network by forming exclusively mono and disulfidic bridges. This results in excellent heat aging resistance of the vulcanizates and prevents premature reversion. Unlike thiurams or morpholine, CLD-80 does not generate carcinogenic N-nitrosamines during vulcanization, nor do the vulcanizates tend towards blooming. Compounds containing CLD-80 exhibit an excellent, broad and sustainable curing plateau. Therefore, CLD-80 is particularly preferred for rubber parts that are exposed to extreme conditions, such as high operating temperatures combined with high dynamic loads (e.g. high-performance tires, seals or anti-vibration elements). Specialty elastomers, which are becoming increasingly common even in standard rubber components, usually require special curing systems. Rhein Chemie offers various curing agents, activators and stabilizers. HMDC-70/AEMD, a crosslinking agent for ethylene acrylic rubber (AEM), is the curing agent of choice for oil resistant seals and hoses based on AEM, ECO/CO and ACM rubber for use in vehicles and engineering. As reinforcing materials, Rhein Chemie has developed predispersed short-fiber pulp masterbatches that support the homogeneous dispersion of the entangled strands in the compound. 6 Global Rubber Performance Catalog Global Rubber Performance Catalog 7

9 PROCESSING PROMOTERS Dispersants and Lubricants Aktiplast products are characterized by their high solubility in diene rubbers. This improves dispersion of the ingredients. Aktiplast affects vulcanization because it provides soluble zinc. Due to their low solubility and the associated lubricant effects, Aflux products optimize the manufacture and processing of rubber compounds. Aflux has no effect on vulcanization. All Aflux grades are zinc-free. Factice The Rhenopren grades, which are polymerized vegetable oils, promote the filler dispersion and plasticizer absorption. They enhance the stability of the unvulcanized mixture. The build-up of pressure in the extruder leads to nonporous final articles, a high extrusion rate and reduced swelling, particularly with large-volume extrudates. The surface appearance can be adjusted individually. Improving the efficiency of compound mixing and processing Processing promoters are additives based on environmentally friendly raw materials, mostly renewable raw materials which can be recycled. They enable producers of tires and technical rubber goods to improve the efficiency of compound mixing and processing, facilitating difficult manufacturing processes. The average elastomer content in rubber articles is 50%, the remainder comprising fillers, plasticizers, chemicals and additives. This often means that more than 10 ingredients with different chemical structures, effects, polarities and consistencies must be processed to form a homogeneous compound. Processing promoters regulate plasticity, homogeneity and flow properties, and have a positive impact on the quality of the finished articles. Using of processing promoters to optimize a process also helps to cut costs: Power consumption and machine wear are reduced because less power is required for mixing Mixing and molding cycles are shortened because of the improved flow properties of the mix Reject rates are reduced due to the high quality of extruded and injection-molded articles With Aktiplast and Aflux, Rhein Chemie not only offers simple dispersants and lubricants, but also a number of specialties in the form of solutions for practical challenges in rubber compounding. Aflux 37 is specially designed for silica compounds based on SSBR, BR, NR, and combinations thereof. Thanks to its defined polarity, Aflux 37 enables silica to be easily incorporated into rubber compounds while not affecting critical physical parameters. More over, higher extrusion rates are obtained due to reduced compound viscosity. Aflux 54 decreases the viscosity of rubber compounds, resulting in easier processing and faster compounding, especially of mixes based on CO, ECO, and FPM. It noticeably reduces the sticking of the compounds to the mixing units. Aflux 54 improves the incorporation of diverse fillers and the extrusion properties of the compounds. Aflux 18 is a dispersant/lubricant especially suited for acrylic rubbers, such as AEM, ACM, and EVM. Aflux 18 significantly reduces the tackiness/ stickiness of rubber compounds based on AEM, ACM, and EVM on metal surfaces. When used in combination with diaminic crosslinking systems (e.g. HMDC-70/AEMD), scorch times can be extended. Compound flowability is improved. Aktiplast 79 is an effective reclaiming agent for natural and synthetic rubber scrap. Aktiplast 79 decreases the risk of cyclization and reduces the reclaiming time. It can be applied in rubber scraps of all kinds. Aktiplast PP is a versatile peptizer and processing promoter for elastomer compounds, e.g. for tires. It decreases the viscosity of compounds based on NR resulting in easier processing. This leads to higher extrusion rates, better dimensional stability and a constant level of die swell. Rhenopren EPS is a processing promoter for natural and synthetic rubber compounds based on vegetable oil, cross-linked without sulfur or chlorine. Rhenopren EPS acts as a polymer plasticizer, giving raw compounds reliable dimensional stability and excellent processability. On account of its minimal influence on vulcanization, Rhenopren EPS can be used both for sulfur and peroxide crosslinking. Resins and Plasticizers The Rhenosin range comprises reinforcing, dispersing and bonding resins. Rhenosin resins are used to adjust viscosity and to create tack in the manufacture of tires and technical rubber goods. They improve processing characteristics during mixing, extrusion, and finishing. They act as phase mediators and filler dispersants in rubber blends. They improve the homogeneity of these mixes and reduce batch-to-batch variation. Under the brand name Rhenosin, Rhein Chemie also offers special plasticizers based on selected ethers/esters. Particularly in polar rubber grades, e.g. NBR, HNBR, ACM, and AEM, Rhenosin plasticizers improve the low-temperature flexibility and elasticity of technical rubber components. Rhenosin plasticizers are highly stable even under conditions of high ambient temperatures. This stabilizes the properties of technical rubber goods at elevated temperatures. With Rhenosin W65, Rhein Chemie offers an eco-friendly plasticizer based on renewable raw materials without compromising performance. Specialty plasticizers for polar compounds marketed under the brand name Vulkanol are now part of the Rhein Chemie portfolio. They are based on either ether thioether or esters. 16 Global Rubber Performance Catalog Global Rubber Performance Catalog 17

13 SPECIALTY AND STANDARD CHEMICALS, Rhenofit, Perkalink, and Vulcuren Practical solutions for compounders The line of standard and specialty accelerators and curing agents includes a selection of specialty products, e.g. dithiophosphates, in the form of dry s. An assortment of standard accelerators in or form rounds out the product line. Dithiophophates are multi-functional solutions to various challenges in rubber compounding. Whatever the task, e.g. N-nitrosamine-free curing systems, formulations for reversion-stable networks, high solubility in rubber, fast curing rates in EPDM extrusion or replacement of otherwise eco-critical chemicals, dithiophosphates from Rhein Chemie are the most efficient solution for every compounder. Accelerators in the Vulkacit range, which are now part of the Rhein Chemie portfolio, can be found in the specialty accelerators section. Retarders in the Vulkalent range are now part of the Rhein Chemie portfolio. You will find these products in the Specialty and Standard Chemicals section of this catalog under the sub-section Retarders. TP/S is a non-staining specialty accelerator for the rapid vulcanization of compounds based on EPDM and other diene rubbers. TP/S causes a high degree of crosslinking. Vulcanizates accelerated by TP/S generally do not show any signs of blooming. EPDM compounds containing TP/S are easy to process and show particularly good flow properties, even in complicated molds. In the efficient vulcanization of NR and other rubbers, such as IR, SBR, NBR, and IIR, TP/S provides vulcanizates with extraordinarily good heat aging resistance. It offers an economic solution for various problems, and not only in the tire industry. SDT/S, a dithiophosphate-based sulfur donor, is recommended as a co-accelerator for various challenges in rubber compounding, e.g. an accelerator for N-nitrosamine-free EV curing systems, an anti-reversion agent for heat-resistant vulcanizates, or for the replacement of standard accelerators. It offers an economic solution for various problems, and not only in the tire industry. Perkalink 900 is a highly effective anti-reversion agent for NR, NBR, IR, (H)IIR, SBR, and BR and their blends. Perkalink 900 is active during long vulcanization times and during thermal degradation to benefit cured articles. The loss of crosslink density caused by reversion is reconstituted to its initial level. Perkalink 900, therefore, is the solution for thick molded articles. Unlike Perkalink 900, Vulcuren is a crosslinker for the production of highly reversion resistant vulcanizates made of NR, IR, SBR, BR, and their blends. Vulcanizates crosslinked with Vulcuren show excellent retention of static and dynamic modulus, superior values in tensile strength, tear strength, hardness, resilience, compresion set, heat build-up, and creep. Vulcuren, therefore, is the right solution for applications with high exposure to heat and dynamic stress. Perkalink 900 and Vulcuren can be found under the sub-section Specialty Curing Agents and Accelerators, Anti-Reversion Agents on the following pages. Rhenofit is Rhein Chemie s brand for a wide assortment of functional additives, including antioxidants, filler and blowing agent activators, crosslinking activators, desiccants and magnesium oxide. Depending on the respective raw material and its handling requirements, these products are offered either in, pellet, or dry form. If not specified otherwise, additives are offered as dry s on inert, inorganic, white, filler material as a free-flowing white for easy handling and mixing conditions. Rhenofit CF, a specially treated, distinctively separated calcium hydroxide, is a crosslinking activator particularly for fluoro elastomers. It is used to achieve optimal compression set values at higher temperatures. Since calcium hydroxide is hygroscopic, Rhenofit CF is supplied in special packaging that keeps the material absolutely dry. Rhenofit CF is the preferred crosslinking activator for fluoro elastomers. Rhenofit STA/S, a combination of activating polar substances bound to highly reinforcing silica, acts as a curing activator and processing promoter for silica and other white fillers. Rhenofit STA/S helps to properly disperse all polar compound ingredients and simultaneously activates silica and other white reinforcing fillers. Vulcanization is accelerated and cure efficiency is improved to such an extent that Rhenofit STA/S can be used as a secondary accelerator. Rhenofit STA/S increases the modulus of vulcanizates. 24 Global Rubber Performance Catalog Global Rubber Performance Catalog 25

Antilux migrates to form a self-regenerating, sealed protective film on the surface of the article. This film is elastic, flexible at low temperatures and has good adhesion properties. Antilux provides optimal protection against oxidation under dynamic stress. The molecular weight distribution of the paraffins determines the ratio of migration to solubility. The protective effects of Antilux can therefore be adjusted to the operating temperature of the finished article.

20 RELEASE AGENTS, TIRE MARKING PAINTS and Rhenomark For safe and reliable handling Release agents are selected individually to suit the manufacturing process, the type, and shape of the finished product, and any finishing the vulcanizate may require. This is why we attach particular importance to active customer service for all applications. Modern release agents are designed to do far more than prevent the adhesion of mechanically processed, uncured rubber compounds. Applied to the surface by spraying, dipping or wiping, the appropriate release agents prevent the sticking of green slabs, sheets, tubes, etc. For the vulcanization of molded articles or tires, custom solutions from Rhein Chemie ensure easy release from the mold together with good surface quality. release agents provide safe and reliable handling at every stage of the production process. That means no dusting, rapid dispersion, reduced foaming, low mold and plant contamination and rapid drying combined with improved quality, safety, and health at work. batch-off release agents prevent the adhesion of uncured rubber, milled sheets, blanks and pellets, and are available in or solid form. mold release agents prevent rubber vulcanizates from adhering to the molds, thereby allowing easier release, and are available in silicone-free or silicone-containing form ( ). tire systems support environmentally friendly tire molding and vulcanization (lubrication, venting, release). Outside/inside paints, semipermanent pro ducts and bladder coatings are available to meet customer requirements. Rhenomark is the brand name of Rhein Chemie for tread marking paints that feature brilliant colors, freedom of VOCs and non-flammability. In order to meet the specific demands of our customers and to provide the greatest benefit, we offer two different product lines: Rhenomark MP and PI. The viscosity and total solids content are the main differences in these grades. The color retains its brilliance even after the tire has been cured, and remains so throughout the storage time of the tires. 38 Global Rubber Performance Catalog Global Rubber Performance Catalog 39

24 TIRE CURING BLADDERS Pre-treated Bladders One typical problem with new bladders is the adhesion of their surface to the tire. To reduce this initial tackiness, it is common practice in the industry to apply a silicone release agent. The first tires cured with these bladders tend to stick to them, shortening bladder life and even pulling them off their clamping, thus increasing overall costs. Rhein Chemie offers different bladder coatings and pre-treated bladders. The coatings reduce tire defects and increase overall bladder life, while also eliminating bladder tackiness. All common bladder sizes are available with a special permanent coating. These bladders offer a variety of improvements to the tire curing process: For special applications, in which no silicone may be used, e.g. run-flat or self-sealing tires, permanently-coated bladders can be used without any refreshment coating. In combination with filled, unfilled or semi-permanent inside lubes or bladder coatings, permanently-coated bladders exhibit a superior service life. Wide Range Rhein Chemie manufactures over 200 different bladder sizes, ranging in rim diameter from 10 to 48. They cover industrial, small farm, motorcycle, passenger, light truck, large truck, agriculture and OTR tire sizes produced with compression and injection molding presses ranging from 36 to 60 in width. The extensive line of Rhenoshape curing bladders, encompassing bias and radial tire applications, is suitable for Bag-O-Matic, Krupp, NRM/ Autoform, Autolok, and Kobe presses. We are constantly developing new sizes and bladder models to suit the needs of tire manufacturers. Rhein Chemie also produces bladders using customer-supplied molds. Superb Performance. Higher ivity. Rhenoshape tire curing bladders, together with the comprehensive portfolio of release agents, provide attractive solutions for tire manufacturers. Rhein Chemie is the only global player that offers both release agents and high-performance tire curing bladders from a single source. Two product lines, perfectly adapted to one another. Steadily increasing requirements on product quality and cost efficiency in the tire industry have led to increasing performance requirements for tire curing bladders. Thanks to innovative bladder designs and advanced compound formulations, Rhenoshape bladders stand for high heat transfer and mechanical resistance, which results in shorter curing cycles, consistent tire uniformity and longer bladder life. Rhein Chemie s competence and experience in bladder design, compounding, -manufacturing and technical service help tire pro ducers to focus more on their core activities. We offer tailored solutions for the complete bladder process to meet customer requirements, making the handling of special bladder-related raw materials and bladder specific operations unnecessary. 46 Global Rubber Performance Catalog Global Rubber Performance Catalog 47
