What are the applications of fluorine rubber in automobiles?
The turbocharger hose is one of the most demanding and costly hoses in the automotive engine. In most cases, aramid fibers are used in the hose structure to maintain the shape and provide the strength of the hose; silicone rubber is used to protect the fiber layer and to make the hose flexible and capable of extremely high temperature. As a result of continuous temperature above 170 DEG C, VMQ (two methyl vinyl silicone rubber) is usually used in the middle and outer layers of the hose. When choosing the elastomeric lining, the manufacturer and / or end user has to choose FVMQ or fluoro rubber FKM.
In recent years, with the improvement of automobile exhaust emission standard, the heat resistance and deterioration resistance of gasoline engine rubber products have been improved accordingly. This is because of changes in the structure of the internal temperature of the engine hood was significantly increased by improving combustion efficiency of oil fuel system leads to the further oxidation of the fuel injection. Therefore, the fuel system, piping, rubber products must be high temperature, heat resistance, oxidation resistance and deterioration of gasoline.
