AI Overview
Polychloroprene Rubber CR3222 (often referred as CR322) is a sulfur-modified, medium-crystallization polychloroprene rubber, similar to DuPont’s Neoprene GW, known for excellent tear strength, superior processability, and high mechanical performance. It is widely used in conveyor belts, driving belts, cable sheaths, and sealing products.
Key Characteristics and Properties
- Composition: Sulfur and xanthogen mixed-modified polymer with a medium crystallization rate.
- Appearance: Beige or amber flakes or lumps, non-polluting.
- Processing: Easy to plasticize, mix-melt, and extrude, offering smooth surfaces and good processing safety.
- Performance: Features excellent tear strength, ozone resistance, and weatherability.
- Density:

Is polychloroprene rubber?
Polychloroprene (CR) was the first commercially developed synthetic rubber and is produced by radical emulsion polymerization of chloroprene and potassium or ammonium peroxodisulphate is used as an initiator (Fig. 6). Polychloroprene was invented by DuPont in 1930 and is best known by the trade name Neoprene.

Is polychloroprene vulcanized?
The mechanism of vulcanization of polychloroprene rubbers, including those modified with sulphur and those containing thiuram in the composition, is usually explained by the assumption that the metal oxides interact with the chlorine atoms present mainly on tertiary carbon atoms [1, 4].
