Synthetic rubber applications demand materials that can withstand diverse operational conditions, from extreme temperatures to aggressive chemical environments. For rubber compounders and manufacturers, selecting the right additives to enhance performance is a critical aspect of product development. Chlorinated Polyethylene (CPE), particularly grades like CPE 135A, offers a versatile solution as both a base material and a modifier for various synthetic rubbers, providing a significant boost in properties. As a dedicated manufacturer and supplier of advanced chemical raw materials, we are at the forefront of providing these innovative solutions.

CPE is a saturated elastomer produced by the chlorination of high-density polyethylene. This process imbues the polymer with a unique set of characteristics that are highly beneficial when blended with other rubbers:

  • Improved Oil and Chemical Resistance: Many synthetic rubbers benefit from enhanced resistance to oils, fuels, and various chemicals. CPE excels in this regard, acting as a protective barrier that prevents degradation and swelling when exposed to these substances. This is invaluable for applications such as automotive hoses, seals, and industrial gaskets.
  • Enhanced Flame Retardancy: The inherent flame-retardant properties of CPE are a major advantage in rubber formulations where fire safety is a concern. This makes it ideal for conveyor belts, wire and cable jacketing, and other applications where ignitability must be minimized.
  • Excellent Weathering and Ozone Resistance: CPE's saturated polymer backbone provides superior resistance to UV radiation and ozone attack, significantly extending the service life of rubber products used in outdoor or exposed environments, such as roofing membranes or automotive weatherstripping.
  • Good Low-Temperature Flexibility: Unlike some other chlorinated polymers, CPE maintains good flexibility at low temperatures, ensuring that rubber components perform reliably even in cold climates.
  • Impact Strength and Toughness: When used as a modifier, CPE can improve the overall toughness and impact resistance of the base rubber, making the final product more durable.

Our expertise as a manufacturer ensures that we supply consistent, high-quality CPE grades tailored for rubber modification.
