POLYCHLOROPRENE (CR)

Neoprene is a commercial name for polymers comprised of chloroprene. Polychloroprene's overall physical characteristics classify it as a general purpose elastomer. Excellent aging characteristics in ozone and weather environments, along with abrasion and flex cracking resistance, justify the general purpose categorization.

Polychloroprene is alkali and acid resistant, flame retardant, and suitable for petroleum based oils. Animal and vegetable fats and greases also provide a highly stable environment for this polymer. Generally speaking, polychloroprene is noted for good compression set, excellent flex fatigue resistance, and resistance to weather and ozone. Its excellent adhesion qualities to metals makes polychloroprene ideal for molding with metal inserts.

Polychloroprene is not effective in aromatic and oxygenated solvent environments.
