Since 2002, the world’s major regions of the automobile industry gradually rise, and the number of cars the increasing, which also means that the automobile industry in a variety of parts, repair, and maintenance in the proper further advantages, the application of silicone products in the automobile industry skyrocketed, and with the deterioration of the environment, more enterprises choose natural synthetic silicone to replace plastic products, such as auto parts, pipes and so on. So in the next few decades, synthetic silicone will occupy the field of auto parts and will be worth our attention.

In the automobile field from 2017 to 2020 statistics, the average demand for natural silicone rubber in a car is 120 kg/ car, which is only for silicone products. The average consumption of polyurethane glue, acrylic ester, and anaerobic glue on the car adhesive can reach 280G. For the automobile natural silicone products industry in 2020, the nationwide application can be up to 5579 tons, and the total vehicle has nearly risen to nearly 300 million. In the face of large and small auto parts, so silicone products manufacturers are conscientious in the design of auto parts. Why silicone rubber is chosen for auto parts and products? This is because silicone products have unique properties and advantages enough to replace other products!

Faced with the huge demand in the automotive field, silicone products manufacturers for automotive sealing products, shock absorption products, and other auto silicone parts have exquisite production technologies, now auto parts for the appearance and performance of the product have higher requirements, so now manufacturers will deliberately to make the material of the product has the corresponding requirements. For example, the hardness and elasticity of the above requirements are relatively high, so the selection of material will look for reasonable raw materials and curing agents, the production process of mold development and mold line adjustment will do the customer’s needs to meet the standards!

 Automotive Silicone Products

• Brake Hose

Due to the emergence of the maintenance cost-free car, the increase of the working temperature of the brake fluid, and the use of high boiling point brake fluid, there is a trend of replacing butadiene silicone rubber with EPDM inside and outside the brake rubber hose. The brake rubber hose’s external and internal rubber layer is mostly EPDM silicone, and the reinforced layer uses polyester, polyethanol, or rayon fiber. The inner adhesive layer can be pressure-resistant polyamide, and the outer adhesive layer can be chloro-sulfonated polyethylene.

• Oil Hose

Due to the use of unleaded gasoline and the development of the direction of high oxidation value, resulting in the corrosion of fuel to silicone, the inner layer of the fuel hose must have good fuel resistance. The inner rubber layer has been developed to use fluorine silicone, chloroethene silicone, or acrylate silicone instead of nitrile silicone to reduce the permeability of fuel and further improve the heat resistance of silicone rubber.

• Power Steering Hose

The development of automobiles has put forward the requirements of high heat resistance and high durability for the silicone rubber hose. The inner silicone rubber layer should have good oil resistance, and the outer layer should have wear resistance, heat resistance, weather resistance, and other characteristics. At present, the inner and outer layers of the hose have been converted from nitrile silicone and chloroprene silicone to hydrogenated nitrile silicone, chlorosulfonated polyethylene silicone, chlorinated polyethylene silicone, and acrylic silicone, and the reinforced layer is mainly nylon 66.
