Product Description

Product Introduction

Chlorinated rubber is a kind of chlorinated polymer prepared by the reaction of natural rubber and chlorine. Industrial products are white or light yellow powder, non-toxic and tasteless, with a chlorine content of 65% ± 2 and an average relative molecular weight of 5000-20000. They are easily soluble in aromatic hydrocarbons, halogenated hydrocarbons, ethers, esters, petroleum solvents, ketones (except acetone) and other organic solvents, and can be miscible with alkyd resins, epoxy resins, phenolic resins, polyurethane and other synthetic resins, and insoluble in aliphatic hydrocarbons, alcohols and water.
 

 

Products Features

Due to the high content of chlorine atoms in the C-C main chain of chlorinated rubber and its ring structure, it has many excellent application properties:

1. The molecular chain structure is saturated and does not contain active groups such as double bonds, so it has stable chemical properties and excellent corrosion resistance, and can withstand the corrosion of acid-base, salt, chlorine, H2S, SO2 and other corrosive chemicals;
2. CL group has mould proof and flame retardant properties, so the products have mould proof and flame retardant properties;
3. C-Cl bond has strong polarity, so it has good adhesion on the surface of steel, aluminum alloy, cement, wood and other materials;
4. With C-C main chain, it is a rubber modified product, so it has good compatibility with natural rubber, neoprene, nitrile rubber and other rubbers;
5. It has a ring structure, so the adhesion, flame retardancy, oil resistance and elastic modulus of the product can be improved;
6. Micro decomposition above 125 ºC, no softening and combustion above 200 ºC, with good heat resistance.

Product application

Chlorinated rubber is one of chlorinated polymers obtained from natural rubber or synthetic rubber after chlorination modification. Because of its excellent film-forming property, adhesion, corrosion resistance, flame retardancy and insulation, it can be widely used in the manufacture of adhesives, marine paint, container paint, chemical anti-corrosion paint, road marking paint, fire-proof paint, architectural paint and printing ink. It is one of the chlorine fine chemical products with great development prospects. In addition, due to the high chlorine content, chlorinated rubber will not burn. Therefore, it is a valuable raw material for manufacturing fire-proof and corrosion-proof paint.
