Shijiazhuang RuiSuo Seal Supplies Co., Ltd. www.ruisuoseal.com O-rings are widely used in the automotive, aviation, chemical, petroleum, pharmaceutical, food and other industries. Common applications include: Engine seals Fuel system seals Chemical delivery systems Hydraulic systems Vacuum equipment Semiconductor manufacturing equipment Because O-rings are used in different scenarios, the requirements for the products vary greatly. In order to meet these different requirements, our laboratory needs to conduct multiple proportioning and experiments on the materials before we can start molding and manufacturing. To provide a clearer and more intuitive view of the characteristics of O-rings in different materials, we have compiled a table to represent the material properties.

NBR Nitrile Rubber Sealing Ring Suitable for use in environments involving petroleum-based oils and fuels. It has excellent resistance to petroleum oils and aliphatic hydrocarbons, but is not suitable for polar solvents such as ketones, ozone, nitro-hydrocarbons, and chlorinated hydrocarbons. Common temperature range: -40~120°C. CR Chloroprene Rubber Sealing Ring Has good resistance to weathering and ozone, with moderate oil resistance. It shows good mechanical strength and abrasion resistance, and is stable under sunlight and ozone exposure. Not suitable for aromatic hydrocarbons or strong acids....
