High Temperature Silicone O Rings Red Black Green Brown Color

Product Name:Euro 2 engine repair kit,Euro 2 engine repair O-Ring, Material:NBR+ + Silicon

NBR Advantages:

NBR is the wildly used oil resistance compound nowadays. It has a great resistance to wear. The –CN contains in Acrylonitrile can affect physical characteristics other than oil resistance. The higher the Acrylonitrile content, the better the resistance to oil. However, the lower the acrylonitrile content, the better the resistance to low temperature. NBR is used at temperature between -25°C~100°C. The life time of rubber will shorten when temperature exceeds 100°C.

FKM Advantages:

Fluorocarbon (FKM/FPM) is a well-known rubber with high performance and a co-polymer composed of highly fluorinated hydrocarbons. It shows excellent resistance to high temperature, fuel oil, hydraulic oil, ozone, media and aging. However, it is unstable to polar solvent, such as MEK, acetone and ethyl acetate. The parts made with FKM generally refer to the fluorocarbon contented with 66% of fluorine, which is also known as ®. FKM is used at temperature between -25°C~200°C for long term operation. The instantaneous temperature can reach 250°C, however, the life time of rubber will be shorten.

Silicon Advantages:

1. The formulated tensile strength reached 500PSI and resistance reached 88LBS.

2. Good and with good compression deformation.

3. Good resistance to neutral solvent.

4. Excellent heat resistance.

5. Excellent cold resistance.

6. Excellent resistance to ozone and oxide erosion.
