Application
NBR compounds have excellent wear resistance, non-polar oils and solvents, water and permeability (higher acrylonitrile)
The content will be better). NBR can also be used at low temperatures under conditions of dilute acid, base and salt solutions.

O-ring material
Service temperature
For NBR, the service temperature can be designed from -55 °C to 100 °C or up to 130 °C, depending on the acrylonitrile content
And the formula.
Service temperature
For the general type of Viton, in static applications, the use temperature is best limited to between -26 and 232 °C, but
In dynamic applications, the use temperature can reach 275 °C in a short time, and it is suitable for between -15 °C and 200 °C.
Application
Because FKM has excellent resistance to high temperature, oil, solvent, flame, chemical and weather resistance, it is usually applied
Automotive, chemical processing, aerospace and many other industries
Silicone O-ring (Q, MQ, VMQ, PVMQ)
*Service temperature
For silicone, the use temperature is -60 °C to 225 °C. Some special types can be used for extreme temperatures up to 300 °C
Down to -100 °C.
Application
Silicone rubber performs well in environmental and temperature extremes. It is commonly used in automotive and aerospace
Industries where flexibility and longevity are important. It is also a suitable material for parts that require food grade
Handling equipment and appliances.
Application
PU has high mechanical strength, high wear resistance, abrasion resistance and extrusion resistance, high pressure load capacity, and high elongation against tearing and breaking.
PU is suitable for mineral oils and greases, hydraulic oils, silicone oils and greases, highly non-flammable hydraulic oils HFA and HFB and water up to 50 ° C.
Service temperature
Compared to other plastics, PTFE has lower mechanical properties, but its properties remain at useful levels over a wide temperature range of -100 °F to + 400 °F (-73 °C to 204 °C).
Application
PTFE is a commonly used sealing material for the manufacture of wear rings, gaskets, O-rings, washers, etc., which can be found in metallurgy
Machinery, petrochemical machinery, engineering machinery, light industry machinery.
Ethylene propylene rubber (EPM, EPDM)
Service temperature
For EPDM, the operating temperature can be designed from -55 °c to 125 °c or up to 150 °c (for peroxide curing systems).
Application
In phosphate based hydraulic fluids and glycol based brake fluid systems, ethylene-propylene rubber is used
The seal. EPDM is also commonly used in hot water or steam applications up to 150 °c.
Fluorosilicone rubber
Service temperature
Fluorosilicone rubber has good physical and mechanical properties and chemical stability, can be in -60 ~
200 °C and short term use below 250 °C.
Application
It is mainly used for the preparation of heat-resistant, oil-resistant and acid-resistant rubber products. Like seals,
Rubber hoses, rubber MATS, tapes, films, fuel tanks and impregnating products are also used
Wire and equipment anticorrosive lining, etc., widely used in aviation industry, petroleum industry, automotive industry,
Chemical industry and other fields.
FFKM oring (Perfluoroelastomer)
Service temperature
It has the elasticity and thermal and chemical stability of teflon. Long-term operating temperature -39 ~ 288 ℃, short-term up to 315 ℃.
Application
Makes the seal resistant to various media, such as rocket fuel, navel orange, oxidizer, nitrous oxide, fuming nitric acid
Acid, etc., used in aerospace, aviation, chemical, petroleum, nuclear energy and other industrial sectors.
Hydrogenated nitrile butadiene rubber
Application
Hydrogenated nitrile butadiene rubber is widely used in oil field, automobile industry and so on
Service temperature
For ACM, the operating temperature can be designed from -10 to 150 °C.
Application
It is used for diaphragms and hoses in automotive applications. Good heat resistance, ozone resistance and oil resistance. It is usually attacked by water, alcohols, dialcohols and aromatics. The molecular structure consists of ethyl acrylate (EA), butyl acrylate (BA) and methoxyethyl
Acrylic ester (MEA). High BA content improves low temperature resistance and high MEA content improves oil resistance.
