Description Polychloroprene is the polymer name for the synthetic rubber known as neoprene.
Application Transmission belts, conveyor belts, wires and cables, oil-resistant rubber sheets, oil-resistant rubber hoses, sealing materials and other rubber products.
Cable jackets, oil resistant hoses, rubber seals, adhesives, etc.
Raw material for adhesive production, used for bonding metal, wood, rubber, leather and other materials.
Cables, rubber sheets, ordinary and oil-resistant hoses, oil-resistant rubber boots, air guides, rain cloths, tent cloths, conveyor belts, conveyor belts, rubber seals, agricultural capsule air cushions, lifeboats, etc.
Features And Benefits This polymer tends to crystallize and harden slowly at temperatures below about 10° C (50° F). It has good physical and mechanical properties, oil resistance, heat resistance, flame resistance, sunlight resistance, ozone resistance, acid and alkali corrosion resistance, and chemical reagent dissolution resistance, but the disadvantage is poor cold resistance and storage stability.
