Chlorinated Rubber (CR)

Short Description:


Product Detail

Product Tags

Introduction
Chlorinated rubber is a low  rubber derivative product which made from natural rubber or synthetic rubber by open rubber mix machine and then is highly chlorinated to come into being modified products,whose technical process is researched and developed by our company independently , different from the old carbon tetrachloride solvent method or water phase method.By our technical process , the performance of adhesion and heat stability is improved largely.

Chlorinated rubber has great solubility in methylbenzene and xylene solution .Due to the saturation of its molecular structure plus large amounts of chlorine atoms in the molecular chain make the material with the synthetical characteristics .Applied in the industrial coating field based on its performance such as oil resistant ,ozone resistance,chemical corrosion resistance and fire retardenace .

Solubility

With great solubility in aromatic hydrocarbons,chlorinated aromatic hydrocarbons, Aliphatic ester ,senior ketone.It is insoluble in petrolemum hydrocarbon and white oil .

Application
After its film formation ,it has not only stable chemical stability but also good impermeability to water and vapor. 
It endures wet chlorine gas ,CO2,SO2,H2S and various other gases (except the wet ozone or acetic acid ), good heat stability.
It does not react with acid ,alkalior other inorganic salt mediums .
It also has high adhesive force with the surface of steel products and cement., widely used for special anti-corrosive paint and adhesives.

Safety and health
The CR (Chlorinated rubber) are high purity chemical product without residual caron tetrachloride and are odorless,non toxic,flame retardant ,stable and are harmless to human body.
