Did you mean: Polychloroprene Rubber CR 2323
AI Overview
Polychloroprene Rubber CR2323 (often referred to as CR232) is a medium-crystallization, sulfur-modified (or mercaptan-modified) polychloroprene elastomer, similar to Type W or M40. It is widely used for producing high-quality light-colored rubber goods, including seals, gaskets, cable sheaths, and automotive parts, due to its excellent resistance to weathering, ozone, oil, and abrasion.
Key Characteristics of CR2323 (CR232):
- Appearance: Milk-white to light yellow chips.
- Modifying Agent: Typically xanthogen or dodecyl mercaptan.
- Properties: Offers superior flexibility, high tensile strength, good compression set resistance, and high-performance aging stability.
- Processing: Known for good storage stability and ease of processing, including being easy to bond.
