EPDM Rubber Engine Coolant Hoses

EPDM Rubber Engine Coolant Hoses

Automobile engine hoses mainly consists of rubber hose and metal hose, which is responsible for the transfer of oil, water, antifreeze, gas and liquid pressure. Among them, rubber hose has the most types, which is the main parts on the automobile. Automobile rubber hose is relatively soft compared with metal hose, prefabricated single, variable shape, so it is used in the cooling, air conditioning and power steering lights application. The main material of automobile hose is EPDM rubber, NBR oil resistant rubber, neoprene, fluoro rubber, ethylene propylene rubber and so on. Automobile hose requires a wide range of ambient temperature;From -40 ℃ to +120 ℃ should be used normally, with corrosion resistance and aging resistance;It also has some hardness and tensile strength. Different uses, different structures, but the overall can be roughly divided into three parts: the inner layer, the middle reinforcement layer and the outer layer.The inner layer is the layer where the rubber hose directly contacts the transmission medium and plays the role of flow diversion and sealing. The inner layer should have a certain thickness and be able to withstand temperature and corrosion.The reinforcing layer is the part of the rubber tube under pressure, which has considerable support strength.It can protect the rubber tube structure and increase the pressure resistance.The outer layer is the protective layer of rubber tube, which plays a defensive role, should have a certain thickness, resistant to temperature, corrosion, friction, aging and other functions.
