2 2 SABIC EuroPetrochemicals Contents Basic facts SABIC Developments in polypropylene grades — Evolution of MFR — Application of nucleators — Multi-functional PP grades Conclusions

3 3 SABIC EuroPetrochemicals SABIC: Saudi Arabian Basic Industries Corporation Started from scratch in 1976, produced first tons in 1983 World wide employees in 22 countries Turn-over of € 11,4 bln in 2002 Is 70% owned by Saudi government and 30% by private sector 100% owner of SABIC EuroPetrochemicals Basic Chemicals IntermediatesPolymersFertilizersMetals

4 4 SABIC EuroPetrochemicals Geleen site SABIC’s first major acquisition outside Saudi Arabia Gelsenkirchen site

5 5 SABIC EuroPetrochemicals West-Europe PP/PE Supply 2003

6 6 SABIC EuroPetrochemicals Developments in polypropylene grades Increasing MFR shorter cycle times thinner wall thicknesses Nucleation Multi functional PP grades

7 7 SABIC EuroPetrochemicals Increasing MFR - evolution of grade portfolio block-copolymers , Melt flow rate (g/10 min) Notched Izod impact (kJ/m²) 1980

8 8 SABIC EuroPetrochemicals Increasing MFR - evolution of grade portfolio block-copolymers , Melt flow rate (g/10 min) Notched Izod impact (kJ/m²)

9 9 SABIC EuroPetrochemicals Increasing MFR - evolution of grade portfolio block-copolymers , Melt flow rate (g/10 min) Notched Izod impact (kJ/m²)

10 10 SABIC EuroPetrochemicals Increasing MFR - evolution of grade portfolio block-copolymers , Melt flow rate (g/10 min) Notched Izod impact (kJ/m²) ? SABIC® PP

11 11 SABIC EuroPetrochemicals Increasing MFR - processing advantages (example MFI 15 vs. MFI 35 grade) FlowMould pressure Cycle timeOutput rate Index figure Traditional grade High MFR grade

12 12 SABIC EuroPetrochemicals Increasing MFR – reduced wall thicknesses ( example MFI 15 vs. MFI 35 grade) ,51,01,52,0 Wall thickness (mm) Flow length (mm) Traditional grade High MFR grade

13 13 SABIC EuroPetrochemicals Improved pail grade: SABIC  PP 612MK , Melt flow rate (g/10 min) Notched izod impact (KJ/m²) New Grade Old Grade MFR 15 SABIC® PP 612MK10 MFR 35

17 17 SABIC EuroPetrochemicals Developments in polypropylene grades Increasing MFR Nucleation increased stiffness better transparency higher crystallisation temperatures Multi functional PP grades

18 18 SABIC EuroPetrochemicals The influence of nucleation nucleated non-nucleated

19 19 SABIC EuroPetrochemicals Nucleation - increased stiffness Flexural modulus [MPa] PP homopolymer PP copolymer Non-nucleated Nucleated

20 20 SABIC EuroPetrochemicals Nucleation - increased transparency

21 21 SABIC EuroPetrochemicals Nucleation - increased transparency Cross-section

22 22 SABIC EuroPetrochemicals Spherulitic growth in praxis In-line thermoforming Sheet thickness = 2 mm PP grade non-nucleated

23 23 SABIC EuroPetrochemicals New SABIC® PP grade for thermoforming Stiffness Clarity nucleated clarified PS PP possibility of down gauging

24 24 SABIC EuroPetrochemicals New SABIC® PP grade for thermoforming Stiffness Clarity nucleated clarified PP possibility of down gauging SABIC® PP 523K

25 25 SABIC EuroPetrochemicals Nucleation - higher crystallisation temperatures (Tc) Addition of nucleating agent Tc

26 26 SABIC EuroPetrochemicals Nucleation - influence nucleation agent (DSC test) Tc

27 27 SABIC EuroPetrochemicals Nucleation - higher crystallisation temperatures; faster cycle times T crystallisation Requiredcooling time

28 28 SABIC EuroPetrochemicals Indentation pin Mold plates Hydraulic cylinder Pressurized oil Ejection pins Injection sprue Cavity Nucleation - influence Tc on cooling time; indentation test Runner (5 mm) Injection point Indentation point

29 29 SABIC EuroPetrochemicals Indentation test Non nucleated PP Nucleated PP

30 30 SABIC EuroPetrochemicals Developments in polypropylene grades Increasing MFR Nucleation Multi functional PP grades reduction in number of PP grades broader application range

31 31 SABIC EuroPetrochemicals Decreasing number of W.European COPOL PP grades nr of COPOL PP grades SABIC EPCComp 1Comp 2Comp 3

32 32 SABIC EuroPetrochemicals Decreasing number of W.European HOPOL PP grades nr of HOPOL PP grades SABIC EPCComp 1Comp 2Comp 3

33 33 SABIC EuroPetrochemicals Reduction in number of PP grades SABIC EuroPetrochemical’s answer: Multi-functional PP grades Broad application area Ultimate product consistency

34 34 SABIC EuroPetrochemicals The multi-functional block copolymer grades for injection moulding offer: Shot to shot consistency Short cycle times Acceptable stiffness / impact balance Dimensional stability Good surface appearance Low blushing performance Good organoleptics

35 35 SABIC EuroPetrochemicals SABIC® PP 412MN40 Multi-functional block copolymers (1) Impact/stiffness Balance Dimensional Stability Cycle time Organoleptic Surface Appearance Tamper evidence

36 36 SABIC EuroPetrochemicals SABIC® PP PHC31 Multi-functional block copolymers (2) Dimensional stability Impact Cycle time Surface Appearance Impact/stiffness Balance

37 37 SABIC EuroPetrochemicals Conclusions Increasing MFR shorter cycle times reduced wall thicknesses Nucleation increased stiffness better transparency higher crystallisation temperatures Multi functional PP grades reduction in number of PP grades broader application range
