Product introduction
Chlorinated Rubber (CR) is a low viscosity rubber derivative made from natural rubber or synthetic rubber through open mill and then highly chlorined to be modified. This product uses the production process independently researched and developed by our company , which is different fromthe old carbon tetrachloride solvent method or water phase method , it can improve all the performance indexes such as product adhesion and heat stability.
Chlorinated Rubber has great solubility in methylbenzene and Xylene solution and due to saturation of its molecular structure, the molecular chain has large amounts of chlorine atoms,hence a great chemical stability is given to this material . That makes it an excellent film-forming resin and adhesive resin, oil resistivity, ozone resistance, chemical corrosion resistance and fire-retardance. After its film formation,it has not only stable chemical stability but also good impermeability to water and vapor. It endures wet chlorine, CO2, SO2, H2S and various other gases (excluding wet ozone or acetic acid) . It has good heat stability (it will break down when heated to above 130℃ meanwhile releasing HCL) and good anti-ultraviolet capacity . It can be stored at room temperature and does not react with acid,alkali or other inorganic salt mediums . It also has high adhesive force with the surface of steel products and cement. It is widely used for specialanti-corrosive paint and adhesives.

Safety and health cautions
The CR products of this company have high purity with no residual carbon tetrachloride and are odorless, non-toxic,flame - retardant, stable and are harmless to human body.
When the CR granularity is too thin, its dust may be inhaled and irritate the respiratory tract, hence, the dust concentration of the environment should be controlled below 10mg/m3.
