Subcategory: Elastomer, TPE; Polymer; Thermoplastic

Close Analogs: 20 Alcryn?TPEs are listed in MatWeb.

Data provided by the manufacturer.

Key Words: Chlorinated Olefin Interpolymer Alloy; Advanced Polymer Alloys; Thermoplastic Elastomer (TPE)

Material Notes:
Alcryn?is a true thermoplastic elastomer, based on a partially cross-linked, chlorinated olefin interpolymer alloy. It is designed for the manufacture of rubber parts with high productivity on thermoplastic processing equipment. 2000 series characteristics: high flow in general plastics processing; designed for injection molding; excellent for complex extrusions; not suitable for calendering; black grades have excellent weather resistance.
