1. Rubber imported rubber flat gasket
Rubber gaskets are widely used in automotive, electronic, chemical, antistatic, flame retardant, food and other industries, such as oil resistance, acid and alkali resistance, cold resistance, heat resistance and aging resistance. Rubber flat gaskets: laminated rubber products, which are sealed between two static surfaces of various mechanical devices, are collectively referred to as rubber gaskets. It can be made by molding or vulcanized. Play the role of cushion, seal, buffer and so on.
1.NBR advantages: wear resistance, oil resistance, water resistance, heat resistance, high pressure resistant oil, good mechanical properties and tightness.
2.NBR disadvantages: imdurable solvent, high temperature resistance
3. temperature: the limit is -40~120 degrees C. the temperature is -20~100 degrees.
4. hardness: A50-90 degrees. The hardness is 70 degrees, and the acceptable pressure is 100kg =10 MPa MPA
5. suitable medium: hydraulic oil, gas, water, mud, crude oil, emulsion, water glycol and acid.
6. the scope of application: machine tools, cars, ships, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and all kinds of instruments and instruments.
7. color: black, green
Note: the above is the performance of butadiene rubber under the conventional modulation condition for reference only. If there are other requirements, you can call to communicate.
Two, NBR imported rubber flat gasket
Because of its versatile performance, O ring has always been favored by customers. Therefore, the seals made of it are also quite extensive, such as: O rings, star rings, flat gaskets, rubber balls, oil seals and so on. Our rubber raw materials are imported from Germany, with excellent performance and high life. In the case of dynamic pressure, his sealing effect is 5-10 times as high as that of the ordinary rubber seal, and the life can even be the same as that of the machine he installed.
The main properties of three and NBR seals
It is high wear-resistant and oil resistant, so it has small friction resistance under conventional working conditions, and the dynamic and static seal is equal. In relative terms, he will not shift under low speed or high speed. NBR with high wear resistance has an automatic elastic compensation function after wear. Its excellent self-lubricating property can be used for oil-free lubrication. It is mainly used for static seal and dynamic seal. Under the condition of rotary motion seal, it is only limited to low speed rotary. The general installation is sealed in a rectangular groove. Good sealing and damping properties make NBR rubber as the most widely used seal in hydraulic and pneumatic transmission machinery.
