The main materials for automotive rubber hoses are generally EPDM rubber, nitrile oil resistant rubber, chloroprene rubber, fluororubber, silicone rubber, etc; Automotive rubber hoses require a wide range of environmental temperatures; From -40 to+120, it should be able to function normally, resistant to corrosion and aging.

Automotive pipelines are mainly composed of rubber pipes and metal pipes. It is responsible for the transmission of oil, water, antifreeze, gas, and liquid pressure. Among them, rubber hoses have the most types and are the main components of automobiles. Compared with metal pipes, automotive rubber hoses are soft, have a single prefabricated component, and have a variety of shapes; Therefore, rubber tubes are commonly used for cooling, air conditioning, and power turn signals.

The main materials for automotive rubber hoses are generally EPDM rubber, nitrile oil resistant rubber, chloroprene rubber, fluororubber, silicone rubber, etc; Automotive rubber hoses require a wide range of environmental temperatures; From -40 to+120, it should be able to function normally, resistant to corrosion and aging. At the same time, it also has a certain degree of hardness and tensile strength.

Although the structure of automotive rubber hoses for different purposes is different, they are generally divided into three parts: inner layer, middle reinforcement layer, and outer layer. The inner layer is the layer where the rubber hose comes into direct contact with the conveying medium, playing a role in guiding and sealing. The inner layer should have a certain thickness, temperature resistance, and corrosion resistance. The reinforcement layer is the compressed part of the rubber hose, which has considerable support strength; Can protect the structure of the rubber hose and increase its pressure resistance; The outer layer is the protective layer of the rubber hose, which plays a defensive role. It should have a certain thickness, temperature resistance, corrosion resistance, friction resistance, aging resistance, etc
