CR is the short form of "CHLOROPRENE RUBBER"
The CL atoms contained is CR and PVC which allow them to have outstanding performance of flame retardance. Noeprene can slowly burn in fire, but the flame will soon be extinguished once Cr is isolated from the fire. Under high temperature, the chlorine hydride gas which is decomposed will extinguish the flame.
Neoprene has high mechanical performance, the tensile strength can reach 20-40pa and the break elongation up to 300-600%.
CR also has high performance for resistance pressure and deformation. As rubber has good elasticity, the great clamping force can be maintained even if it is pressed and deformed for quite a long time.
CR has high anti-wear performance. only about 0.15cm3 of the CR will be worn out if it runs for 1 mile on Akron Abrasion tester
