Definition - What does Chlorinated Rubber mean?
Chlorinated rubber is a type of powdery thermoplastic resin of high hardness. It is considered an environmentally friendly resin.
With excellent adhesiveness, it can be used for chemicals and abrasives. Due to its high chlorine content, it is incombustible and therefore used for making fireproof and anti-corrosion paint. Its films exhibit excellent resistance to corrosive influences.
Corrosionpedia explains Chlorinated Rubber
Chlorinated rubber is a chemically inert material with excellent film-forming properties. It is nonflammable, nontoxic and consists of white powder. Properties include:
- Good weathering resistance
- Fine adhesion ability
- High chemical stability
- Excellent saltwater resistance
- Good ultraviolet resistance
It is readily soluble in organic solvents such as toluene and xylene, 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 glass-like film. It also protects the basal body, prevents corrosion and serves as a top coating for decorative purposes.
Chlorinated rubber can prevent permeation of water vapor and oxygen, and is widely used in the manufacture of various paint, printing ink, binding agents, paper and fabric.
Chlorinated rubber is categorized according to relative molecular mass or viscosity:
- Low-viscosity chlorinated rubbers are mainly used for printing ink additive.
- Medium-viscosity chlorinated rubbers are mainly used for preparing paint.
- High-viscosity chlorinated rubbers are mainly used for making adhesive.
