Precautions when you use chemical composite hose
According to incomplete statistics, more than 20 rubber hoses and hundreds of rubber parts are needed in a car. The changes of develop concept and the requirements of environment protection make special rubber more and more popular. In vehicle, the rubber should be high temperature, oil and abrasion resistant besides excellent performance.
Fluorinated silicone rubber
This kind of rubber has excellent oil and chemical corrosion resistance. It can be used at the temperature from -68-230℃ remaining good seal and liner performance. It has huge advantage when being used in extremely cold or heat conditions. It’s commonly used as fuel oil system sealing, O-ring of engine and speed change system, hose of cooling and heating system and turbocharge system.
Fluoro rubber
It’s reported that over 60% of the fluoro rubber is used in vehicle because its excellent performance in high temperature and complex chemical environment. Because of the oil, oxidation and corrosion resistance, fluoro rubber is used as engine stem sealing, cylinder sleeve sealing and used in many hoses like fuel hose. After being added bisphenol crosslinking, the fluoro will get good performance in alkali resistance, which improve its mechanical capacity contacting with engine oil.
HNBR
Recent years, mixed fuels like ethanol fuel develop rapidly, which is a challenge to automotive rubber. But HNBR can adapt these mixed fuels and remains stable in variety of additives. Because of the oxidation resistance, it’s used as the seal in fuel oil system and carriage. It’s also widely used in various of hoses like oil hose fuel hose in vehicle, especially luxury cars.
