Nature Description

CR122 neoprene is beige or light brown flake or cake, does not contain mechanical impurities outside talc powder, and has no scorched particles. It has good physical and mechanical properties, sunlight resistance, ozone aging resistance, weather resistance, chemical reagent resistance, oil resistance, non-prolonged combustion and better electrical properties. CR232 neoprene is beige flake or cake, does not contain mechanical substances outside talc powder, and has no scorched particles. Excellent storage stability, excellent processing performance and safety. Its products have the characteristics of sunlight resistance, ozone aging resistance, oil resistance and chemical reagents, flame extension resistance, etc, it has good heat resistance and low compression deformation. However, its vulcanization speed is slow, which needs to be solved by adjusting the vulcanized system. Type CR24412442 neoprene is milky white to light brown block, without talc

Product Applications

Used for manufacturing rubber products such as conveyor belt, hose, printing rubber roller, cable, adhesive, antiseptic paint, etc.; Used for asphalt modification, cement mortar modification, underground engineering, building waterproof, fiber treatment, etc.; Used for manufacturing cables, hose, etc.; Used for footwear uppers bonding and igelite floor bonding, etc.; Used for making colored rubber products; Used for preparing adhesive; Used for making elastic cement, adhesive, etc.; Used for manufacturing cable, belt conveyor, etc; CR122 neoprene can be used for wires and electricity..

Production method

The production process of synthetic rubber prepared by emulsion radical polymerization of chloroprene mostly adopts intermittent polymerization. Using sulfur-autumn rum or mercaptan as molecular weight regulator, the polymerization temperature is 40-600 ℃, and the conversion rate is about 90.
