Professional processing customized mechanical equipment factory wear rubber seal temperature UV-resistant oil

 Professional production and processing seal, seal doors and windows, automotive seals, and other products, welcomed the order! EPDM rubber (EPDM) material properties: A, excellent ozone resistance molecular structure and oxidation resistance in the EPDM backbone contain double bonds, it can be completely resistant to ozone in the air attack. Ozone concentration 100PPHM environment, 2430 hours does not appear cracks (butyl rubber 500 hours cracking, Neoprene 40 hours cracking); in 50PPHM, static pull of 30% for 150 hours without cracking ( Butyl rubber two hours cracking). B, excellent weather resistance EPDM long-term use in the sun, wet, cold environment. Vulcanized rubber containing CB in the sun exposure three years will not be cracking, physical and mechanical properties change is small. C, excellent heat resistance EPDM long-term use at 120 ℃ conditions, the highest temperature 150 ℃, when higher than 150 ℃ begins to decompose, when the addition of a suitable anti-aging agents or peroxide, hydroquinone curing system, its intermittent temperature up to 315 ℃. This feature is its saturated backbone structure of the decision. D, excellent low temperature properties of poly methylene main chain flex provides a good low-temperature properties, glass transition temperature between -35 ℃ --65 ℃, most curing products at -25 ℃ conditions still soft That has good flexibility and less compression permanent deformation, so that it will not reduce the ambient temperature is too low and the sealing performance in cold regions, make it easier in cold regions construction at low temperatures. E, chemical resistance EPDM resistant to many polar solutes, such as brake oil, acids, alkalis, alcohol and the like; poor resistance to non-polar solute properties, such as gasoline and other hydrocarbon solvent, etc., through the use of ultra-high molecular oil filled case available under moderate oil resistance. F, EPDM synthetic rubber in almost all the lightest weight (also below plasticized polyvinyl chloride), so the finished product will have a lighter weight per meter. This also determines that they have a wide range of applications. EPDM has many advantages in addition to the above, only a small density EPDM, has excellent electrical properties, good stress - strain characteristics, good abrasion resistance, excellent moisture resistance and resistance to steam products are widely used in residential buildings, commercial buildings, stadiums and bridges and dock fenders crash and so on ...... strong technical force, advanced production machines as well as ten years of production experience and technology. And a professional installation team, a sound service system. Factories have from product design, material preparation, design mold design and manufacture, physical and chemical testing to the entire process of manufacturing, production, quality assurance system. Through the ISO international quality management system certification
