*Service Temperature
For NBR the service temperature can be designed from -55 °C to 100°C or up to 130 °C depending on differenacrylonitrile content
and formula.https://ruihebearing.en.made-in-china.com/product-list-1.html
*Application
NBR compounds have excellent resistance to abrasion, non-polar oils and solvent, water and permeation (higher acrylonitrile
content will be better). NBR also can be used in conditions of dilute acids, alkalis and salt solution at low temperatures.
For general type the service temperature is better limited to approximately from -26 to 232°C in static applications, though
the service temperature can arrive to 275°C at short time In dynamic applications, it is suitable between -15°C and 200 °C.
*Application
Because FKM has excellent resistance of high temperature, oil, solvent, flame, chemicals and weathering, it is usually applied in
automotive, chemical processing, aerospace and many other industries
*Service Temperature
For Silicones the service temperatures are from -60 C to 225°C. Some special types can be used in extrehttps://ruihebearing.en.made-in-china.com/product-list-1.htmlme temperature up to 300°C
and down to -100°C.
*Application
Silicone rubber performs well under environmental and temperature extremes. It is usually applied in automotive and aerospace
industries where flexibility and longevity are important. It is also a suitable material for parts that need food grade for food
handling equipment and appliances.
Fluorosilicone rubber has good physical and mechanical properties and chemical stability, and can work for a long time at -60 to
200°C, and short-term use below 250°C*Application Mainly used in the preparation of heat-resistant, oil-resistant, acid-resistant rubber products. Such as seals,
rubber hoses, rubber pads, tapes, tapes, films, fuel tanks and impregnated products, etc., can also be used as outer sheaths of
wires and anti-corrosion linings of equipment, etc., widely used in aviation industry, petroleum industry, automobile industry,
chemical industry Industry and other fields
PTFE's mechanical properties are low compared to other plastics, but its properties remain at a useful level over a wide
temperature range of -100°F to +400°F (-73°C to 204°C).
*Application
PTFE is the common sealing material used for making wear ring, backing-up ring, o ring, gasket, etc. It can be found in metallurgy
machinery, petrochemical machinery, engineering machinery, and light industrial machinery.
For EPDM the service temperature can be designed from -55 C to 125 C or up to 150 C (for peroxide cured systems).
*Application
In phosphate-ester based hydraulic fluids and glycol based brake fluids systems Ethylene Propylene Rubber is good choice for
sealing parts. EPDM is also is usually used in hot water or steam applications up to 150 C.
other polymers, it can better meet the requirements of the automotive industry.*Application Hydrogenated nitrile rubber is widely used in oil fields, automobile industry, etc.
