Chloroprene Rubber CC2442: High-Strength, Fast-Crystallizing Neoprene for Industrial Applications
Chloroprene Rubber CC2442 is a specialized grade of synthetic rubber made from chloroprene (2-chloro-1,3-butadiene). Belonging to the broader family of chloroprene rubbers (CR), CC2442 is a sulfur-modified, crystallizing type known for its fast crystallization, high tensile strength, and excellent adhesive properties. It is widely used in the adhesive industry, automotive parts, rubber product manufacturing, and industrial applications where durability and bonding strength are critical.
CC2442 is formulated to offer enhanced tack, strong initial bonding, and durability under stress. Due to its superior resistance to ozone, weathering, oil, and aging, this chloroprene rubber grade is highly sought-after for solvent-based adhesives, especially in leather goods, footwear, and construction laminates.
