High Corrosion Resistance Chlorinated Rubber from China Factory - Suppliers of Quality Polymers
Application Properties
1. 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.
2. The Cl₄ group is mildew-resistant and flame-retardant, resulting in products with these properties.
3. The C-Cl bond is highly polar, resulting in excellent adhesion to a variety of surfaces, including steel, aluminum alloys, cement, and wood.
4. Its C-C backbone makes it a modified rubber product, offering excellent compatibility with rubbers such as natural rubber, chloroprene rubber, and nitrile rubber.
5. Its cyclic structure enhances the product's adhesion, flame retardancy, oil resistance, and elastic modulus.
6. 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.
Frequently Asked Questions
What are the key chemical resistance properties of Chlorinated Rubber?
Chlorinated rubber has a saturated molecular chain structure without double bonds, which provides exceptional chemical stability. It is highly resistant to corrosive elements such as acids, alkalis, salts, chlorine, H₂S, and SO₂.
Why does Chlorinated Rubber offer excellent adhesion to surfaces?
The high polarity of the C-Cl bond in chlorinated rubber provides outstanding adhesion properties. This makes it highly compatible with and adhesive to various substrates, including steel, aluminum alloys, cement, and wood.
What are the specifications of CR-10 Chlorinated Rubber?
CR-10 chlorinated rubber is a white to slightly yellow powder with a chloride content of ≥ 65%. It features a viscosity of 10-12 MPa.s (in 20% xylene solution at 25°C), ash content of ≤ 0.38, transparency of 90-92, and volatile content of ≤ 0.28%.
Is Chlorinated Rubber flame-retardant and heat-resistant?
Yes. The Cl₄ group provides inherent flame retardancy and mildew resistance. Chlorinated rubber exhibits excellent heat resistance with minimal decomposition above 125°C, and it does not soften or combust above 200°C.
What industries and applications use Chlorinated Rubber?
It is widely used in manufacturing adhesives, marine and container coatings, chemical anti-corrosion paints, road marking paints, fire-retardant paints, architectural coatings, and printing inks due to its film-forming and protective properties.
