CMR648

CMR648 is a water insoluble, general purpose polypropylene (PP) impact copolymer containing a nucleating agent. Exhibits medium flow, anti-static, rapid crystallization, excellent impact/ stiffness balance, excellent impact toughness properties at low temperatures (-30°C) and shorter cooling times. Is suitable for processing by injection molding. Recommended for bottle crates, dairy, industrial crates, transport & storage containers, buckets, folding boxes, tool cases and garden tools.
