Intercooler is one of the important components of turbocharging. When the air is compressed, the air temperature is too high, which will cause the air to expand, which will directly affect the mixed gas volume entering the cylinder. Therefore, it is necessary to cool the compressed air before entering the cylinder to increase the amount of mixture entering the cylinder, so that the inflation efficiency is increased and the engine power is enhanced. The intercooler plays the role of cooling the air, so that the high temperature air is cooled by the intercooler and then enters the engine.

The use temperature of the air inlet hose of the automobile intercooler is as high as 150℃ ~ 275℃, and the material must meet the excellent high and low temperature property, good oil resistance and weather resistance.

In silicone rubber, acrylic rubber, fluorine silicone rubber, fluorine rubber and other materials with excellent high temperature resistance, the material that does not have good oil resistance is silicone rubber, but silicone rubber is the cheapest of these four materials, of which acrylic rubber, fluorine silicone rubber, fluorine rubber prices are 2 times, 17 times, 6 times. In this way, if the rubber material in the intake hose of the intercooler in the closed structure oil and gas separation system is fluorine silicone rubber and fluorine rubber, it does not have a cost advantage, but the high temperature resistance of acrylic rubber is only about 175 ° C, and it is only suitable for the engine with small horsepower or 1.5T displacement.

With the development of the automotive industry, it has been developed from traditional materials to new modified materials, and the application of high reliability and low cost polymer materials has promoted the further development of the automotive industry. I hope that the relevant information about the materials used in the automotive intercooler hose can be helpful to you.
