Material Notes:

Alcryn melt-processable rubber (MPR) is a true rubber, based on a partially cross-linked, chlorinated olefin interpolymer alloy. Alcryn is designed for the manufacture of rubber parts with high productivity on thermoplastic processing equipment.Applications:Window and door weatherstripping (and other complex profile extrusions)Soft handles and gripsMolded seals and gasketsInjection-molded and co-injection molded partsBlow-molded partsTubing and hoseWire and cable jacketsCoated fabrics and sheet goodsInformation provided by Advanced Polymer Alloys
