are widely used, mainly used as wire and cable sheaths, rubber hoses, oil-resistant rubber products, heat-resistant conveyor belts, printing rubber sticks, rubber dams, building sealing strips, road caulking sealants, bridge supports, and oil field wires Waterproof caps, flame-retardant rubber products, various sealing rings, anti-corrosion linings for chemical equipment and neoprene adhesives, etc. In recent years,
Chloroprene rubber is produced by emulsion polymerization, and the production process is mostly single-pot batch polymerization. The polymerization temperature is mostly controlled at 40-60 degree , and the conversion rate is about 90%. In production, the sulfur-thiuram (tetraalkylmethylaminothiocarbonyl disulfide) system is used to adjust the molecular weight.
CR122 Neoprene: rubber products such as transmission belts, conveyor belts, wires and cables, oil-resistant rubber sheets, oil-resistant rubber hoses, and sealing materials.
CR232 Neoprene: cable sheath, oil-resistant hose, rubber seals, adhesives, etc.
CR2441/CR2442 Neoprene: raw material for adhesive production, used for bonding metal, wood, rubber, leather and other materials.
CR321/CR322 Neoprene: cables, rubber sheets, ordinary and oil-resistant rubber hoses, oil-resistant rubber boots, air guide tubes, rain cloths, tent cloths, conveyor belts, conveyor belts, rubber seals, agricultural capsule air cushions, lifeboats, etc. Used as a toughening agent for modified acrylate fast structure adhesives (SGA).
