Rectangular ring butadiene rubber, plastic molding (rubber product molding)
The characteristics of nitrile rubber rings are as follows:
1. High temperature resistance.
The most prominent feature of nitrile rubber ring is its high temperature resistance. It can work for a long time under working conditions ranging from 200 ℃ to 250 ℃, and is not limited to this. It can also work for a short time under high temperatures of 300 ℃.
2. Climate aging resistance and ozone resistance performance:
Nitrile rubber rings have excellent aging resistance and ozone resistance.
3. chemical stability/corrosion resistance:
Nitrile rubber rings have excellent corrosion resistance. Generally speaking, its stability against organic liquids (fuel oil, solvents, hydraulic media, etc.), concentrated acids (nitric acid, sulfuric acid, hydrochloric acid), high concentration hydrogen peroxide, and other strong oxidants is superior to other types of rubber.
4. Electrical performance: The electrical insulation performance of nitrile rubber ring is relatively average, and the temperature has a significant impact on its electrical performance, that is, as the temperature increases, the insulation resistance significantly decreases. Therefore, fluororubber is generally not suitable as an insulation material for use at high temperatures.
5. Flame retardancy: the flame retardancy of nitrile rubber ring depends on the halogen content in the molecular structure. The higher the halogen content, the less likely it is to burn. Fluorine rubber can burn when in contact with flames, but it automatically extinguishes after leaving the flame, so it belongs to the self extinguishing type of rubber.
6. Radiation resistance: Nitrile rubber rings are materials that are resistant to moderate doses of radiation. The radiation effect of high-energy rays can cause the cracking and structuring of fluororubber, and the radiation resistance of nitrile rubber rings is one of the relatively poor types of elastomers.
