Chlorinated Rubber Suppliers and Factory in China for High Corrosion Resistance Applications
Application Properties
The molecular chain structure is saturated, lacking reactive groups such as double bonds. This results in chemical stability and excellent corrosion resistance, making it resistant to a variety of corrosive chemicals, including acids, alkalis, salts, chlorine, H₂S, and SO₂.
The Cl₄ group is mildew-resistant and flame-retardant, resulting in products with these properties.
The C-Cl bond is highly polar, resulting in excellent adhesion to a variety of surfaces, including steel, aluminum alloys, cement, and wood.
Its C-C backbone makes it a modified rubber product, offering excellent compatibility with rubbers such as natural rubber, chloroprene rubber, and nitrile rubber.
Its cyclic structure enhances the product's adhesion, flame retardancy, oil resistance, and elastic modulus.
It exhibits excellent heat resistance, exhibiting minimal decomposition above 125°C and no softening or combustion above 200°C.

Product Applications
Chlorinated rubber is a chlorinated polymer derived from natural or synthetic rubber through chlorination. Due to its excellent film-forming, adhesion, corrosion resistance, flame retardancy, and insulation properties, it is widely used in the manufacture of adhesives, marine and container paints, chemical anti-corrosion paints, road marking paints, fire retardant paints, architectural coatings, and printing inks. It is a highly promising chlorine-based fine chemical product. Furthermore, due to its high chlorine content, chlorinated rubber is non-flammable, making it a valuable raw material for the manufacture of fire-retardant and anti-corrosion paints.
