Borealis PP BC250MO
抗冲击共聚聚丙烯
Borealis AG
产品说明：
BC250MO is a very high impact polypropylene heterophasic copolymer intended for injection moulding. This grade is characterized by combination of good stiffness, good creep resistance and very high impact strength even at low temperatures. This grade features high impact strength, high thermal stability and very good processability. As all polypropylenes, this grade shows excellent stress-cracking and chemical resistances.
This grade is mildly nucleated to maximize the mechanical stiffness. The additive formulation provides a ***ooth demoulding. Nucleation, good flow properties and high stiffness create a high potential for cycle time reduction. Its very good organoleptic properties allows this grade to be used with any masterbatch without discoloring problems.
