Description

Polychloroprene is a versatile synthetic rubber known for its excellent resistance to oil, weather, ozone, and heat, making it a critical material in demanding industrial applications. Its unique balance of properties, including good mechanical strength and moderate flame resistance, provides reliable performance where other elastomers fail. This polymer is essential for manufacturers in the automotive, construction, marine, and adhesive industries seeking durable, weather-resistant components.

Application

• Automotive Components: Used in hoses, belts, vibration dampeners, and seals due to its oil and weather resistance.
• Industrial & Construction Seals and Gaskets: Ideal for weather-stripping, bridge bearing pads, and expansion joints because of its ozone and weathering resistance.
• Adhesives and Coatings: Serves as a base for high-strength contact adhesives, protective coatings, and roof mastics.
• Marine and Diving Gear: Employed in wetsuits, drysuits, and protective covers for its flexibility and water resistance.
• Cable Jacketing and Conveyor Belts: Provides durable, flame-retardant, and abrasion-resistant sheathing and belting.
• Vibration Isolation Mounts: Used in machinery mounts and anti-vibration pads for its good dynamic properties.

Quality Control

Our polychloroprene is manufactured under strict process controls to ensure batch-to-batch consistency and performance reliability. Quality is verified through a series of tests including Mooney viscosity, specific gravity, and residual monomer content. Certificates of Analysis (COA) detailing all relevant 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 away from heat sources and incompatible materials. Recommended storage temperature is 15-25°C. Protect from moisture to prevent premature curing or degradation.
