Reduction in number of PP grades

SABIC EuroPetrochemical’s answer:

Multi-functional PP grades

Broad application area

Ultimate product consistency

34


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
