Application
It is a synthetic chloroprene rubber, which can be used in the manufacture of wire, cable, oil-resistant rubber plate, hose, conveyor belt, transmission belt, rubber sealing material and other rubber products.
In addition, CR122 neoprene is a kind of pollution general neoprene rubber, which is especially suitable for the production of color or light color rubber products.
CR232 neoprene rubber can be used in the production of oil resistant rubber pipe adhesive, cable sheath, rubber seal, etc., and is widely used in adhesive manufacturing.
CR2441 2442 neoprene rubber is the basic raw material for adhesive production. Its preparation is used for bonding rubber, leather, wood, metal and other materials.
CR321 322 neoprene rubber is widely used in the manufacture of all kinds of cables, neoprene wires, ordinary and oil-resistant rubber pipes, rubber sheets, air guide tubes, various conveyor belts, tent cloth, rain cloth, oil-resistant rubber boots, various rubber seals, agricultural capsule air cushions, lifeboats, etc. CR322 is more suitable for all kinds of color or light color products.
