1 Bio-based Building Blocks - Priplast Taipei, 24 th May 2017

2 Bio-based Building Blocks Company introduction Raw materials Technology Features & benefits Conclusion

3 Our History

4 Where We Operate

5 Our Technologies Speciality alkoxylates Esters Bio-based dimer acids Proteins & biopolymers Fatty amides Polymeric surfactants High purity lipid concentrates Plant cell culture Plant extraction technology Peptides Metal oxides Lanolin & derivatives

6 Pripol Dimerised Fatty Acid Unsaturated, natural oils and fats C=C C=O C=C-C-C=C C=O heat, pressure, catalyst C=O separation O=C HO C=O trimerised fatty acid O=C HO C=O dimerised fatty acid C=O isostearic fatty acid

7 General Features Pripol Dimer Acids Bio-based from natural fatty acids Large hydrocarbon part (C 36 ) hydrophobic hydrolytic resistance of derivatives affinity for non-polar matrices and surfaces O=C HO Irregular non-crystalline structure flexibility low Tg flow, wetting low modulus, no strain hardening no shrinkage C=O Di-functional constituent for: polyamides polyesters polyurethanes epoxies polyimides

8 Different Forms Dimer Technology Dimer acid Pripol Dimer diol Pripol HOOC HO CO Polyester polyols Priplast HO---- E--E n Dimer diamine Priamine H 2 N NH 2

9 Priplast Technology Hydrocarbon nature Bio-based No ether linkage Stability against heat, oxygen and UV Hydrophobicity Hydrolytic stability Low moisture absorption Affinity for low polarity matrices and surfaces Non-crystalline structure Flexibility, low Tg No strain hardening Good flow and wetting Good adhesion to a wide range of substrates Hydroxyl functionality Reactivity in: polyurethanes, co-polyamides, co-polyesters etc. E--E n

10 Low Moisture Absorption of PU Priplast brings water resistance vs. conventional polyols Moisture uptake at 23 o C (%) To limit performance difference in wet or dry conditions Recipe : 1 Polyol 2 Butanediol 3.1 MDI Conditions : 1 week in H 2 O dist. Priplast 3196 Priplast 1838 Poly BD Priplast 3190 HDO carbonate Priplast 3192 HDO-adipate Polycaprolactone BDO-adipate PTMEG PPG

11 Hydrolytic Stability of PU in Boiling Water Priplast brings good hydrolysis resistance Retention of tensile strength [%] Priplast: hydrolytic and oxidative stability To resist moisture for enhanced durability ester: hydrolysis ether: oxidation PTMEG HDO-adipate Priplast Days Recipe : 1 Polyol 2 Butanediol 3.1 MDI Conditions : Boiling water

12 Durability: Thermo-oxidative Stability Priplast improves stability vs. other polyols Retention of tensile strength / elongation [%] ester Strength Elongation To resist thermal oxidation for enhanced durability ether; fell apart unsaturated diol; no ether / ester BDO-adipate Priplast 1838 PTMEG PPG Poly BD PU elastomer Recipe : 1 Polyol 2 Butanediol 3.1 MDI Conditions: 4 weeks at 140 o C

13 Mechanical Properties Flexible and no strain-hardening, ca. 600% elongation Recipe: 1 polyol 2 BDO 3.1 MDI crystalline adipate PTMEG Priplast 3192 (semi-crystalline) Priplast 1838 (amorphous) Poly BD/rubber Strain

14 10 0 Flexibility: Low T g of Polyurethanes Priplast brings flexibility also at low temperatures Glass transition temperature [ o C] To be flexible even at low temperatures HDO-adipate Polycaprolactone Priplast 3192 Priplast 3196 Priplast 1838 PPG Priplast 1838 (*) PTMEG Priplast 3190 Recipe : 1 Polyol 2 Butanediol 3.1 MDI P1838 (*) =

15 Summary Bio-based Priplast Durability Hydrolysis and thermo-oxidative resistance Chemical resistance Excellent moisture repellency Flexibility Rubber-like behaviour (best comparison PTMEG), no strain hardening Low temperature flexibility Excellent flow properties Up to 100% renewable carbon content
