O-rings, physical properties of different materials

Product catalog summary

Overview: Shijiazhuang RuiSuo Seal Supplies Co., Ltd. specializes in the production of O-rings, which are essential components in various industries such as automotive, aviation, chemical, petroleum, pharmaceutical, and food. These O-rings are used in applications like engine seals, fuel systems, chemical delivery systems, hydraulic systems, vacuum equipment, and semiconductor manufacturing equipment.

Material Specifications:

NBR (Nitrile Rubber): Suitable for petroleum-based oils and fuels, with a temperature range of -40 to 120°C. Not suitable for polar solvents.
CR (Chloroprene Rubber): Offers good weathering and ozone resistance, with moderate oil resistance. Temperature range: -55 to 120°C.
HNBR (Hydrogenated Nitrile Rubber): Provides excellent heat, ozone, and chemical resistance. Suitable for automotive air conditioning systems. Temperature range: -40 to 150°C.
IIR (Butyl Rubber): Good resistance to sunlight, ozone, and polar solvents. Poor oil resistance. Temperature range: -40 to 110°C.
SIL (Silicone Rubber): Outstanding temperature resistance, suitable for food and medical applications. Poor tensile strength. Temperature range: -55 to 250°C.
ACM (Acrylic Rubber): Good resistance to heat, ozone, and mineral oils. Temperature range: -25 to 170°C.
VITON (Fluorine Rubber): Excellent resistance to high temperatures and chemicals. Not suitable for amines. Temperature range: -20 to 220°C.
NR (Natural Rubber): High elasticity and mechanical strength, poor aging resistance. Temperature range: -20 to 100°C.
FVMQ (Fluorosilicone Rubber): Combines properties of fluorine and silicone, excellent oil and fuel resistance. Temperature range: -50 to 200°C.
PU (Polyurethane Rubber): High wear resistance, not resistant to hot water. Temperature range: -20 to 120°C.
EPDM (Ethylene Propylene Diene Rubber): Excellent weather and chemical resistance, poor petroleum fluid resistance. Temperature range: -55 to 150°C.
FFKM (Perfluoroelastomer): Exceptional chemical resistance, suitable for high temperatures. Temperature range: -25 to 320°C.

Conclusion: The document provides a comprehensive overview of the different types of O-rings available, highlighting their specific material properties, suitable applications, and temperature ranges. This information is crucial for selecting the appropriate O-ring for specific industrial applications.

O-rings, physical properties of different materials-1

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.
