Description

Polychloroprene Rubber CAS NO 69028-37-1 is a synthetic elastomer renowned for its excellent resistance to oil, weather, ozone, and heat. This material matters for industrial applications requiring a durable, flexible rubber that maintains performance in harsh environmental conditions. It is critically needed by manufacturers in the automotive, construction, marine, and wire & cable industries for components like seals, gaskets, hoses, and adhesives.

Application

• Automotive Components: Used in vibration dampeners, seals, hoses, and belts due to its oil and weather resistance.
• Industrial Seals and Gaskets: Ideal for creating reliable seals in machinery exposed to oils, solvents, and outdoor conditions.
• Construction Materials: Employed in bridge bearing pads, expansion joints, and waterproofing membranes for its durability and flexibility.
• Marine and Diving Gear: A key material for wetsuits, drysuits, and other equipment requiring water and ozone resistance.
• Adhesives and Coatings: Serves as a base for high-strength contact adhesives and protective coatings.
• Wire & Cable Jacketing: Provides excellent insulation and sheathing that resists degradation from sunlight, heat, and chemicals.
• Conveyor Belts and Hoses: Used in manufacturing belts and hoses that handle abrasive materials or operate in demanding environments.
• Vibration Isolation Mounts: Applied in machinery mounts and antivibration pads for its energy absorption properties.

Quality Control

Our Polychloroprene Rubber is manufactured under strict quality management systems to ensure batch-to-batch consistency and performance. Quality is verified through a series of tests including Mooney viscosity, specific gravity, and residual monomer analysis. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from sources of heat, sparks, and open flame. To prevent premature cross-linking or degradation, avoid prolonged storage in high-humidity environments or in direct contact with copper and its alloys.
