Material Notes:
BC545MO is a low-blush polypropylene heterophasic copolymer intended for injection molding. This grade features high impact strength, high thermal stability and very good process ability. 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 long-term heat stability. Its very good organoleptic properties allows this grade to be used with any master batch without discoloring problems. Applications: suitcases, battery cases, crates and boxes, and technical parts.Information provided by Borealis AG
