Chlorinated Rubber

Chlorinated rubber, which was developed by our company recently, is a kind of environment friendly resin. The chlorination process carries on in the aqueous phase, does not use the organic solvent completely, it has avoided the disadvantage that caused by using the CCl₄ method chlorination9 a kind of method that adopted by some plants recently), and the latter has not permitted by the Environmental Protection Law. It has the all excellent physical chemical properties of the solvent method chlorinated rubber, is its ideal substitution product. Its development has successfully filled the domestic blank of aqueous phase chlorinated rubber's production technology.

Chlorinated rubber is a kind of thermoplastic resin of high hardness and powdery. It has good weathering resistance, fine adhesion ability, high chemical stability, excellent salt-water resistance and good ultraviolet resistance. It is readily soluble in organic solvents such as toluene, xylene, acrylic resin, alkyd and other esters, forming a colorless or yellow transparent solution. When this solution is applied to the surface of metal , concrete, paper etc, the solvent readily vaporizes at room temperature and forms a layer of transparent, hard and glossy glassiness film. This thin film can prevent the steam and the oxygen penetration, it shows very high stability to various chemicals (for example acid, alkali, etc.) has the very high stability to each chemical substance as well. It also protects the basal body, prevents it from corrosion, and also serves as a top coating for decorative purposes. In addition, because this product has the very high chlorinity, therefore has the fine flame resistance.

Chlorinated rubber is widely used in the oil paint, coating, printing ink and the binder. Its price is lower than of chlorinated rubber produced by using the solvent method, so it is a kind of functional resin with good ratio of ability and price.
