Insulating high temperature resistant materials tell you the resistance to oil and chemicals from the molecular structure (oil and chemical resistance) is EPM rubber and EPDM rubber is so polarized by light. It is not oil resistant or rubber. Non-polar solvents (such as natural rubber and SBR), but will tolerate polar solvents well. The rubber is resistant to acid, alkali, alcohol, human hydraulic oil on water surface. And contains solvent oxygen composition is good. Oil resistance, animal oil to moderate. But not to solvents containing halogen compounds. Acid concentration of straight chain hydrocarbon solvents (aliphatic hydrocarbon solvents) and cyclic hydrocarbon solvents (aromatic hydrocarbon solvents).

The insulating (insulated) rubber is resistant to power specifications that are very high, so the tire has high dielectric strength and even at high temperatures the tire type maintains the properties of the dielectric well. It has very little water absorption. Very suitable for rubber cables used in cables exposed to water. Tire rubber EPMEPM and EPDM rubber have higher dielectric strength EPDM rubber small comparison.

Through low temperature (low temperature flexibility) tire bending. EPDM is flexible at low temperatures, as well as close to natural rubber.

High temperature applications (high operating temperature) EPDM has been stabilized with sulfur and high temperature in low tires has been repaired with peroxidation in general EPDM can be used. Temperature range from -40℃ to 150℃, usually rubber withstand up to 165℃ to 125℃ or a month and a year at 100℃ for 5 years property heat resistant tire wear a factor. Others such as the amount of anti-aging and diene rubber used in the pivot.

EPDM strip three cars are stabilized by using hydrogen peroxide or sulfur with a highly active catalyst, however, to keep the tires using peroxide EPDM rubber containing enough fractions of a grade. Lima ethylene high due to methyl polypropylene will break the link with peroxide while maintaining it will cause the broken molecule, not applied to the still image with the perry rubber grade chain. The north titanium oxide is the copolymer of ethylene with more than 50% mole number plus diene molecules also affecting the still image with peroxides and rubber DCP-EPDM is the rate. Fixed rate with peroxide. More than rubber ENB-EPDM pies (rubber, although this will have a fixed rate of lower sulphur content than most).

High temperature resistant silica gel strip manufacturers tell you that stable EPDM rubber with peroxide needs to fill in a few substances to increase the density of the link. The stimulation will react with free radicals produced by the decomposition of peroxides. There are many reactions. Stimulants are widely used as sulfur catalysts to decompose sulfur sources such as Crimean modulated quinones.
