Classification of rubber Butadiene rubber (NBR) Advantages: excellent resistance to gasoline and aliphatic oils, second only to polysulfide rubber, acrylate and fluororubber, superior to other rubber. Butadiene rubber has good heat resistance, air seal, abrasion resistance and water resistance. Disadvantages: cold and ozone resistance is poor, strength and elasticity is poor, acid resistance is po...
Rubber seal is a kind of general basic element in the sealing device. The high elasticity of rubber plays an important role in the contradiction between leakage and sealing, and it is widely used in daily life.Common seals in our lives have sealing ring, rubber gasket, rubber o-ring, v-ring, y-ring and so on. Rubber has high elasticity at room temperature. It is the only polymer material with high...
The most important characteristics of EPDM are the ability to resist oxidation, ozone and erosion, as well as excellent vulcanization.Among all the rubber industries, EPDM has the lowest proportion. It can absorb a large amount of fillers and oils with little influence, so it can produce rubber compounds with lower cost. By adding EPDM material, it can have higher tensile and tearing strength, hig...
In many car mat material, rubber and plastic is the most widely used, which mainly benefits from rubber and plastic material itself excellent skid resistance, wear resistance, anti-static, pollution resistance and other properties, an excellent rubber, plastic pad pollution resistance ability, convenient cleaning, by the majority of car owners love and welcome.What need to notice nevertheless is, ...
The structure and materials of automotive rubber hoses vary according to their use, performance, function, medium used, and ambient temperature. The selection of rubber materials plays a decisive role in the performance of hoses. Automobile hoses are in contact with various media, and the use conditions are harsh and technical requirements are harsh. It is a composite rubber product with many vari...
With the application of unleaded gasoline and electrospraying devices in automobiles, the structure of the fuel hose has undergone great changes in the material, and the inner rubber layer has been developed to replace the nitrile rubber with fluororubber, chlorohydrin rubber or acrylate rubber. In order to reduce fuel permeability and further improve heat resistance, the inner layer rubber is mos...
