What is the role of silicone hose in the automotive industry

Silica gel is a new type of polymer elastic material, which has excellent high temperature resistance (250 ~ 300 ℃) and low temperature resistance (- 40 ~ 60 ℃), good physiological stability, can withstand repeated and harsh disinfection conditions, excellent resilience and permanent deformation (no more than 50% after 48 hours at 200 ℃), breakdown voltage (20 ~ 25 kV / mm), ozone resistance and ultraviolet resistance. Special silica gel has radiation resistance and oil resistance. Silicone tube is widely used, and steam work will become the future development direction of silicone tube.

Automobile silicone hose is used to transport gas and liquid silica gel products. It is composed of inner and outer rubber layers and skeleton layers. The skeleton layer materials can be made of polyester cloth, aramid cloth, polyester cloth, etc. the inner and outer bonding layer materials of automobile silicone hose are made of ordinary silica gel raw materials, oil resistant rubber pipes, acid resistant, alkali resistant and other materials. Fluorosilicone is used in high temperature resistant automobile pipes.

As an important part of automobile, automobile silicone hose is distributed on the engine, chassis and body. It plays a role in oil, gas, water and power transmission for the safety and performance of automobile. At present, a car should use at least 20 meters of hose, and the number of hose combinations used on luxury cars has reached more than 80 h, and there are at least 10 kinds. Automotive hose has the characteristics of straight pipe, special-shaped pipe, high pressure, low pressure, pressure vacuum, oil and gas, heat dissipation, refrigeration and cooling, braking, driving, pressurization and transportation, and has become the representative of today’s advanced technology of rubber hose. The display field of various new rubber hoses is constantly developing to the field of high and new technology. Structurally, it has coexisted in many forms, such as cloth, weaving, rolling and so on.
