Success Case

Application product display
   
     Ethylene Diene Monomer has excellent ozone resistance, weather resistance, heat aging resistance, good chemical corrosion resistance, electrical insulation performance, hot water and steam resistance, and low temperature resistance. Therefore, EPDM is mainly used in automotive parts (scrapers, seals, dustproof rubber sleeves and other sealed shock-absorbing products), chemical-resistant hoses, rubber rollers, gaskets, etc., as well as high, medium and low voltage insulation Rubber material

 

SBR styrene butadiene rubber compound

"Polymerized Styrene Butadiene Rubber (SBR) has physical and mechanical properties, processing properties, and product performance similar to natural rubber. Some properties, such as wear resistance, heat resistance, aging resistance, and vulcanization reversion, are superior to natural rubber. It can be used in combination with natural rubber and a variety of synthetic rubbers, and is widely used in the production of tires, tapes, rubber tubes, wires and cables, medical devices, and various rubber products.", It is a larger general-purpose synthetic rubber variety and one of the earliest rubber varieties to achieve industrial production.
