Chlorinated Polyethylene Rubber CM Series - Top China Suppliers & Factory for High-Quality Elastomers
Product Introduction
In recent years, FINE CM is increasingly used to replace some traditional materials to upgrade the end products performance for its excellent heat-aging and superior ozone resistance. FINE CM series also get booming used in many industrial hoses in replacing some well-established materials such as CR due to concerns over high cost and availability.
Different HDPE raw materials (different molecular weight and molecular weight distribution), adjustable production formulations and process make the FINE CM series can be broadly used for a variety of industrial fields in the Rubber market in large scale by its different chlorine contents and Mooney Viscosities.
