Peroxide-Cured EPDM Material

Chemical peroxide-cured EPDM (ethylene-propylene-diene monomer rubber) particles are widely used。

Chemical Peroxide-Cured EPDM Mainly Including The Following Aspects

• Automotive industry: used to manufacture various seals, shock absorbers, dust covers, radiator hoses, etc. for automobiles, because these parts need to maintain stable performance in high temperature environments.

• Construction industry: used to produce weather-resistant seals, door and window seals, roof waterproof membranes, etc., which need to be exposed to various climatic conditions outdoors for a long time.

• Wires and cables: used to manufacture high-temperature and chemical-resistant cable insulation layers, especially in situations where flexibility and heat resistance are required.

• Aerospace: In the aerospace field, it is used to manufacture non-structural parts such as seals and gaskets inside aircraft, which need to maintain performance under extreme temperatures and pressures.

• Industrial applications: used to manufacture seals, hoses and protective covers in various industrial equipment, which need to maintain reliability in high temperature and chemical corrosion environments.

• Medical devices: In medical devices, EPDM materials can be used to manufacture parts of certain medical devices due to their biocompatibility and high temperature resistance.

• Sports and leisure: used to manufacture surface materials for sports venues, seals for swimming pools and other outdoor leisure facilities, which require materials to have good weather resistance and aging resistance.

• Power industry: used to manufacture insulating parts in power equipment, such as cable joints and insulating sheaths, which need to work stably under high temperature and high pressure environments.

These applications of peroxide cross-linked EPDM materials demonstrate their diversity and importance in modern industry. Through peroxide cross-linking, the performance of EPDM materials has been significantly improved, enabling them to meet a variety of demanding application requirements.
