What is Polychloroprene CAS 9010-98-4?
Chloroprene rubber is abbreviated as CA. It is produced by emulsion polymerization of 2-chloro-1,3-butadiene monomer. It can be modified with sulfur and 2,3-dichloro-1,3-butadiene. Chloroprene rubber has high tensile strength and superior properties in terms of heat resistance, light resistance, aging resistance, and oil resistance compared to natural rubber and butyl rubber.
The appearance is a milky white to beige or light brown sheet-like or block-like substance, without any mechanical impurities other than talcum powder, and without burnt particles. It is soluble in various organic solvents such as ethanol, acetic acid, and acetone, and slightly soluble in ethylene glycol and water. It is prone to polymerization under the presence of light, heat, electrical discharge radiation, and catalysts. Its molecular weight is generally 10 to 200,000, with a relative density of 1.15 to 1.25, a glass transition temperature of -45℃, is polar, has a regular molecular arrangement and reversible crystallization properties.
Polychloroprene CAS 9010-98-4 Use
Chloroprene rubber is a type of synthetic rubber. It is a linear α-polymer structure obtained by emulsion polymerization of 2-chloro-1,3-butadiene. It serves as a vulcanizing agent and enhances the resistance to thermal aging. Not only can it rival natural rubber in physical and mechanical properties, but it also possesses properties such as oil resistance, solvent resistance, oxidation resistance, aging resistance, acid resistance, alkali resistance, heat resistance, flame resistance, and flexibility that natural rubber and other general synthetic rubbers do not have. It can be used as a general rubber or a special rubber, and is employed in the manufacturing of rubber products such as conveyor belts, rubber hoses, oil-resistant rubber products, heat-resistant conveyor belts, printing rubber rollers, rubber dams, building sealing strips, road joint sealants, bridge bearings, oil-resistant wire waterproof caps for power plants, flame-retardant rubber products, various Chemicalbook sealing ring pads, and chemical equipment anti-corrosion linings and chloroprene rubber adhesives. In recent years, chloroprene rubber has been developed for new applications in building waterproof materials, sealing materials, adhesives, marine development, healthcare, energy development, and people's daily lives, expanding its application fields.
CR122 type chloroprene rubber can be used in the manufacturing of various rubber products such as wires, cables, oil-resistant rubber sheets, rubber hoses, conveyor belts, transmission belts, and rubber sealing materials. In addition, CR122 type chloroprene rubber is a type of general-purpose chloroprene rubber that is particularly suitable for the production of colored or light-colored rubber products. CR232 type chloroprene rubber can be used to produce oil-resistant rubber hoses, cable sheaths, rubber seals, etc., and is widely used in the manufacture of adhesives. CR24412442Chemicalbook type chloroprene rubber is a basic raw material for adhesive production. Its formulation is used for bonding materials such as rubber, leather, wood, and metal. CR321322 type chloroprene rubber is widely used in the manufacture of various cables, chloroprene cloth wires, ordinary and oil-resistant rubber hoses, rubber sheets, air ducts, various conveyor belts, transmission belts, tent fabrics, rain covers, oil-resistant rubber boots, various rubber seals, agricultural capsule air cushions, lifeboats, etc. CR322 is more suitable for various colored or light-colored products.
