| HG385MO is a polypropylene homopolymer intended for injection moulding. This grade combines unique Borstar reactor design with Borealis Nucleation Technology (BNT) to produce highly-crystalline polypropylene. This product is characterized by excellent flow properties combined with a narrow molecular weight distribution well suited for low distortion products. This grade contains anti-static and slip additives, which result in short cycle time, good demoulding and low dust attraction. Products moulded from this grade exhibit excellent dimension consistency combined with high stiffness. Applications Caps and closures Items requiring good antistatic properties Special Features High stiffness Excellent antistatic properties&& |
