Borealis Borpact™ SG930MO Polypropylene Copolymer  (discontinued **)
Categories: Polymer; Thermoplastic; Polypropylene (PP); Polypropylene Copolymer

Material Notes: Borpact™ SG930MO is a random heterophasic copolymer intended for injection molding. This grade yields high transparency and deep freeze impact resistance combined with excellent flow properties. and is designed for high-speed injection molding and contains nucleating and antistatic/demolding additives. In addition, components have good gloss, very low stress whitening and excellent taste and odor properties. Products molded from this grade have an excellent balance of see-through transparency and deep freeze impact resistance. Applications: ice cream containers, crates, deep freeze boxes for food storage, bread boxes, flip top caps, and high gloss closures.
