AI Overview
Polychloroprene Rubber CR3221 (often referred to as CR322 or Chang Shou CR3221) is a general-purpose, medium-crystallization chloroprene rubber, sulfur-modified for high tear strength, excellent processing, and resistance to oil, ozone, and heat. It is widely used in rubber manufacturing for products like hoses, cable sheaths, belts, and seals.
