precision 99 alumina ceramic insulating tube bush Reputation depends on quality,  quality comes from Hard! Alumina Ceramics: The modified varieties of alumina ceramic polyethylene mainly include chlorinated polyethylene, chlorosulfonated polyethylene, cross-linked polyethylene and blended modified varieties. Alumina ceramics are random chlorides obtained by partially replacing hydrogen atoms in polyethylene with chlorine. Chlorination is carried out under the initiation of light or peroxide, and is mainly produced by aqueous suspension method in industry. Due to the difference in the molecular weight and distribution of the raw material polyethylene, the degree of branching, the degree of chlorination after chlorination, the distribution of chlorine atoms and the residual crystallinity, chlorinated polyethylene can be obtained from rubber-like to hard plastic-like. The main purpose is to be used as a modifier of polyvinyl chloride to improve the impa…
