Acrylate rubber hydraulic seals seals use - Xinhua Xu

 

Acrylate rubber seals for all kinds of car accessories dominant, often referred to as car rubber, primarily for high-temperature seal.

 

Xinhua Xu acrylate rubber is widely used in high-temperature, heat oil products. Due to the poor resistance of silicone rubber, nitrile rubber low heat resistance, oil resistance and heat resistance in terms of overall performance, Xinhua Xu acrylate rubber after fluorine rubber, ranked second in the raw rubber varieties, it is to create 180 ? Xu Xinhua rubber seals used at high temperatures, Xinhua Xu O-rings, gaskets and Xinhua Xinhua Xu Xu hose suitable material. In the conditions of use are not very demanding, but with lower fluorine rubber uneconomical situation, acrylate rubber can be selected.

 

Since the speed and processing power of the automobile industry trends appear, for in addition to improving engine cylinder capacity, but focus on the development of high-speed, high compression ratio of modern engines, causing the temperature of the rotating part of the engine increases, furthermore small hydraulic drive system of savings also contributed to increase the heat, so the temperature of the hydraulic oil can be up to 150 ~ 160 ?.

 

Plus countries in energy conservation and environmental protection aspects related to increasingly stringent regulations and restrictions, which are heat resistance and technical performance of the seal fitting new demands. At the same time in order to prevent the decomposition of oil required to join the extreme pressure additive, it has damaging effects on a variety of rubber, thus making use of nitrile rubber is greatly limited. Acrylate rubber as suitable for high temperature extreme pressure lubricant material application rapidly expanded to become one of the materials on the automotive industry indispensable.

 

Xinhua Xu acrylate rubber in the amount of the largest car gearbox seals, rod seals, followed by the spark plug caps, radiator or heater hose, valve stem oil guards and adhesive cork pads, sponges, pads, and other. It compared with the silicone rubber and nitrile rubber, it can be summarized in Table 15-10.

 

In the automotive seal material, currently abroad, about 70% still use nitrile rubber; 30% acrylic ester rubber, mainly due to acrylate rubber processing difficulties, as well as the performance of the compression deformation, good low temperature performance reasons .

 

In addition to the automotive industry, many excellent features Xinhua Xu acrylate rubber has such ozone resistance, air tightness, resistance, flex resistance to sunlight and aging, it has great potential, such as for sponges, oil seal pads, diaphragms, special hose and tape, equipment capacity, the deep exploration rubber products. In the electrical industry, partial replacement of the price of expensive silicone rubber for high temperature in contact with the oil wire, cable sheathing, electrical use washers, casing. In this application will improve with the acrylic rubber cold resistance, and expanding. Further, since the transparency of the acrylic rubber and good adhesion with the fabric, and thus in the adhesive paste and the application of the coating material is gradually increased. In addition, the liquid used for transporting special steel lining, shock absorbers, cushioning pad.
