quality Import rubber o-rings manufacturers believe that rubber O-rings used in automobiles are deformed by pressure during use and have a sealing effect. Must have good elasticity and low compression set and ageing resistance. In different parts of the car and the sealing medium is different, the O-ring is required to have good oil resistance, high and low temperature resistance, low compression set and certain tensile strength. If it is used as a dynamic seal, wear resistance and Tear resistance.

　　quality Import rubber o-rings manufacturers suggest that the sealing rubber O-rings for automobiles must be adapted to various conditions such as the working conditions of the automobile, the type of medium, the operating temperature, the working pressure and the application state. Judging from the rubber O-rings currently required for various parts of automobile assembly, such as the O-rings of fuel injection devices, they are mainly made of FKM (fluororubber). Ordinary rubber parts can meet the requirements with nitrile butadiene rubber (NBR) with different acrylonitrile content.

　　quality Import rubber o-rings manufacturers found that some parts of the car, such as under the hood, the temperature continued to rise, must be changed to fluorine rubber, the use of ordinary rubber can no longer meet the requirements. In addition to paying attention to the selection of rubber materials, the sealing O-rings for automobiles are also continuously improved in mold development and mold processing accuracy, such as 45-degree parting surface molds, flash-free molds, and injection molding technology. Efforts in research and development, to catch up with the international advanced level.
