EPDM is ethylene, propylene, mix a small amount of the conjugate olefin copolymer, is one of the types of ethylene propylene rubber, expressed in EPDM, because its main chain is made up of chemical stability of saturated hydrocarbon, and only in the side chain containing unsaturated double bond, so the ozone resistance, heat resistance, excellent weather resistance and aging resistance, can be wid...
Nitrile rubber is mainly produced by low-temperature emulsion polymerization, with excellent oil resistance, high wear resistance, good heat resistance and strong adhesion. NBR contains acrylonitrile, the more acrylonitrile content, the better oil resistance, but the corresponding cold resistance will decline.It can be 150 ℃ 120 ℃ in air or in the oil medium and long term use. It can be widely use...
With the development of aerospace, automotive parts and medical devices, the requirements for precision and dimensional stability of rubber products in harsh environment are becoming higher and higher.For example, the radiator coolant hose of heavy truck needs to withstand high temperature and high pressure, and the diameter of the hose is generally large, most of which are made of silicone compos...
The rubber hose mainly has the automatic hose and the tubing, mainly USES for the liquid and the gas transportation.The pipe must be well sealed. Products heat resistance, aging resistance, durable requirements determine the need for high quality production, so we should carefully choose partners.Factories more than ten years, partners to maintain long-term cooperation, factory management is in pl...
Rubber is a kind of polymer material with high elasticity, different products have different requirements for different rubber, these requirements have resistance to strength, aging, high and low temperature, oil and so on.The properties of rubber mainly depend on the types of raw rubber used and the different formulations of rubber materials. Natural rubber (NR) has excellent resilience and is ma...
1.Type O sealing ring: type O sealing ring are widely used in all kinds of machinery, all kinds of petroleum base oil and various chemical medium resistance: don't use analysing can meet - 60 c ~ + 200 degrees Celsius (double fluoro rubber FFKM after vulcanization in a certain way can reach more than 300 degrees), the temperature of the area, using the pressure range: < 10 mpa (hydraulic), <...
