Description

Polychlorobutadiene CAS NO 9063-70-1 is a synthetic polymer derived from the chlorination of butadiene, characterized by its chlorine content and elastomeric properties. This material is valued for its enhanced chemical resistance, flame retardancy, and weatherability compared to standard hydrocarbon rubbers. It serves as a critical raw material for manufacturers in the elastomer, adhesive, and specialty coating industries, where performance under demanding conditions is essential.

Application

• Flame-Retardant Elastomers: Used as a base polymer or additive in rubber compounds for cables, hoses, and industrial belts requiring fire resistance.
• Adhesive Formulations: Imparts tack, cohesion, and chemical resistance in solvent-based or hot-melt adhesives for construction and automotive applications.
• Specialty Protective Coatings: A key component in corrosion-resistant and weatherproof coatings for marine, industrial, and infrastructure assets.
• Oil & Gas Seals and Gaskets: Formulated into components that must withstand exposure to oils, fuels, and harsh chemicals.
• Polymer Modification: Acts as a compatibilizer or property enhancer when blended with other polymers to improve flame retardancy and chemical stability.
• Wire and Cable Insulation: Provides a halogenated barrier in insulation and jacketing materials for enhanced safety.
