Description
MPU/EPU (Polyurethane rubber) is a high-performance elastomer that combines the elasticity of rubber with the abrasion resistance of plastic. This material offers excellent mechanical strength,tear strength, and wear resistance, far exceeding that of conventional rubber materials.
Applications
Oil-resistant and emulsion-resistant seals
Rubber rollers
Shock absorbers
Conveyor belts, tracks

Advantage
1.Excellent abrasion resistance: 3-10 times that of natural rubber, and more than 5 times that of conventional rubber.
2.Very high mechanical strength
3.Excellent oil and solvent resistance
4.Very low compression set: Quickly returns to original shape after compression, ensuring long lasting sealing performance.
5.Good low-temperature flexibility: Maintains good flexibility and elasticity even at -40°C.
