The main purpose

Nitrile rubber

NBR

Excellent oil resistance, high wear resistance, good heat resistance and strong adhesion. The disadvantages are poor low temperature resistance, poor ozone resistance, poor insulation performance and slightly lower elasticity. Nitrile rubber is mainly used in the manufacture of oil-resistant rubber products.

Minimum temperature: -30℃

Maximum temperature: 100℃

Used to manufacture O-rings and oil seals, suitable for general hydraulic and pneumatic series seals

Hydrogenated nitrile rubber

HNBR

It has good resistance to media, heat and oxidative degradation. The heat resistance is between FKM and NBR, and the wear resistance is also better than NBR.

Minimum temperature: -30℃

Maximum temperature: 150℃

It is suitable for sealing of high temperature, chemicals and heat resistant hydraulic oil, and is widely used in metallurgy, electric power and other industries.

fluororubber

FKM

Heat resistance, acid and alkali resistance and other chemicals: oil resistance (including phosphate ester series hydraulic oil) is suitable for all lubricating oil, gasoline, hydraulic oil and synthetic oil.

Minimum temperature: -20℃

Maximum temperature: 230℃

It is suitable for sealing of high temperature resistance, chemicals and fire-resistant hydraulic oil, and is widely used in metallurgy, electric power and other industries.

Silicone Rubber

PMQ or VMQ

Good heat and cold resistance, small compression set, but low mechanical strength.

Minimum temperature: -60℃

Maximum temperature: 200℃

Suitable for high-speed and low-friction rotary seals and food mechanical seals at high and low temperatures.

Ethylene propylene rubber

EPM or EPDM

Good weather resistance, aging resistance in air, general oil resistance, Freon resistance and various refrigerants

Minimum temperature: -50℃

Maximum temperature: 150℃

It is suitable for various automobile oil seals and various gearboxes and gearboxes, and can withstand medium and high temperature.

Teflon

PTFE

Good chemical stability, good heat resistance, good cold resistance, oil, water, steam, chemicals and other media. High mechanical strength, high pressure resistance, good wear resistance, low friction coefficient and excellent self-lubrication.

Minimum temperature: -200℃

Maximum temperature: 260℃

It is used to manufacture O-rings, Y-rings, dust-proof rings, etc., and is used for sealing of construction machinery and high-pressure systems.

Polyurethane

PU

Good mechanical properties, excellent wear and oil resistance, limited working environment temperature

Minimum temperature: -35℃

Maximum temperature: 120℃

Used in refrigerators and refrigeration machinery to seal

Acrylate rubber

AEM
