Model CR70-CR150 is a high-viscosity chlorinated rubber with excellent properties such as being wear-resistant, corrosion-resistant, flame retardant, tough, highly adhesive. It can be used both as base material and supplementary material. In the former case, it may be used along with halogenated polyolefins, aromatic nitroso compound or isocyanate products, so to improve the adhesion; and in the latter case when used as auxiliary material, it is generally used as a modifier additive to increase the strength of adhesive film, improve bonding joints, especially for conditions of high temperature or those calling for high durability and resistance to various chemicals, such as for chloroprene rubber, nitrile rubber and polyurethane adhesives.
