Material: PU
Hardness:90-95 Shore A
Color: Blue/Green
Operation conditions
Pressure: ≤ 400 bar
Temperature: -35~+100℃
Speed: ≤1m/s
Media: almost all media hydraulic oils(mineral oil-based)
High sealing performance under low pressure
Not suitable for sealing singly
Easy installation
1. Sealing performance
The polyurethane seal has a good dust-proof effect, it is not easy to be invaded by external substances, and prevents external interference, even if the surface is sticky and foreign objects can be scraped off
2. Friction performance
High wear resistance and strong extrusion resistance. The polyurethane seal can move back and forth at a speed of 0.05m/s without lubrication or in a pressure environment of 10Mpa.
3. Good oil resistance
Polyurethane seals will not be corroded even in the face of kerosene, gasoline and other fuels or mechanical oils such as hydraulic oil, engine oil and lubricating oil
4. Long service life
Under the same conditions, the service life of polyurethane seals is 50 times more than the seals of NBR materials. Polyurethane seals are more superior in terms of wear resistance, strength and tear resistance.
