Chlorinated Rubber (CR) Suppliers in China - High-Quality Thermoplastic Resin from Trusted Factory
Product Introduction
Chlorinated Rubber (CR) is a high hardness, powdered thermoplastic resin. And it is a derived product modified from the natural rubber through chlorination. It has excellent properties of weather resistance, adhesion, chemical stability, salt water resistance, UV protection, etc.
Chlorinated Rubber can be stably dissolved in toluene, xylene and other organic solvents, and acrylic acid, alkyd and many other resins, forming colorless or yellow transparent liquid. When this solution is applied to metal, concrete, paper and other surfaces, the solvent evaporates at room temperature, leaving behind a transparent, hard, shiny, glassy film. This film prevents the penetration of water vapor and oxygen, meanwhile is highly stable to various chemicals, such as acids and bases. It protects the substrate against corrosion and can be used as a topcoat for decoration. In addition, this product has excellent fire-resistance due to its high chlorine content.
In coatings to remarkably improve the coating properties such as weatherability and water resistance, insulation, inflammability, anti-acidity, anti-alkali, adhesion as well as impact strength. The chlorinated rubber coatings is widely applied to surface protection of materials for severe situation, such as shipping, offshore platforms, bridges, docks, containers, motor vehicle chassis, road signs, chemical equipment, etc. Additionally, high viscosity chlorinated rubber is applied to high-strength adhesives production, or added into other rubber products to improve its quality, while the low-viscosity product is applied to high-grade ink making.
