Explanation
macromolecule materials obtained by polymerization of 2-chloro-1,3-butadiene monomer. In industry, persulfate is used as initiator, sulfur, thiuram or mercaptan as molecular weight regulator, and sodium alkyl sulfonate and rosin soap as emulsifier, which are produced according to emulsion polymerization process. The content of trans 1,4-structure is about 85%, which is more crystalline than natural rubber and styrene butadiene rubber. chloroprene rubber has good physical and mechanical properties, and its tensile properties are similar to those of natural rubber. crude rubber has high tensile strength and percentage elongation after fracture, and has the ability of self reinforcing parts. At the same time, chloroprene rubber has excellent aging resistance, flame resistance, oil resistance, solvent resistance, water resistance and air tightness, but poor low temperature resistance and storage stability. Mainly used for wires and cables, various hoses and tapes, waterproof device protective layers, submarine cables, automotive components, and adhesives.
