Chloroprene Rubber (CR), commercially known as Neoprene, is a high-performance synthetic elastomer produced via the emulsion polymerization of chloroprene monomers (2-chloro-1,3-butadiene). It bridges the gap between general-purpose natural rubber and specialized high-cost synthetic polymers, providing a balance of mechanical strength and chemical stability.
Chemical & Oil Resistance: Resists degradation from petroleum oils, grease, fuels, and organic solvents.
Ozone & Weathering Resistance: Exceptional stability against direct sunlight, UV exposure, and environmental aging.
Inherent Flame Retardancy: The chlorine atom in its molecular structure endows it with self-extinguishing properties under heat or flame exposure.
Broad Operating Temperature: Retains flexibility and structural performance across a temperature range of -40ºC to +120ºC.
High Mechanical Durability: High tensile strength, tear strength, and excellent compression set recovery.
Unlike conventional sulfur-cured natural rubber, Chloroprene Rubber is vulcanized using metal oxides:
Zinc Oxide (ZnO): Acts as the primary cross-linking agent for the polymer chains.
Magnesium Oxide (MgO): Functions as an acid scavenger to neutralize chlorine traces during thermal processing, improving heat aging stability.
