Borealis PP BC545MO Borealis Polypropylene Impact Copolymer

Product Description

BC545MO is a low-blush polypropylene heterophasic copolymer intended for injection moulding. 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 characterized by combination of high stiffness, very high impact strength and low stress whitening.

This grade is mildly nucleated to maximize the stiffness-impact balance. The additive formulation provides longterm heat stability. Its very good organoleptic properties allows this grade to be used with any masterbatch without discoloring problems.
