Advantages of Polyurethane Over Rubber
1. Excellent wear resistance:
Among the known wear-resistant rubbers, it enjoys the reputation of "wear-resistant rubber". In the case of wet wear, its wear resistance is more than 10 times that of ordinary rubber.
2. Wide range of hardness:
It can produce a variety of products between A20 and A98, and can still maintain high elasticity under high hardness, which is not available in other materials.
3. Excellent mechanical properties:
The tensile strength of ordinary natural rubber and neoprene adhesive is generally less than 30Mpa, and that of polyurethane elastomer reaches 40~70Mpa. Its tear resistance is much higher than that of ordinary rubber, and its load capacity is very high.
4. Excellent oil resistance:
Similar to the oil resistance of nitrile rubber in traditional rubber; excellent oxygen resistance and ozone resistance.
5. High surface finish.
6. The adhesion to the metal core is much higher than that of ordinary rubber, and it is suitable for high-speed and high-pressure applications.
7. Polyurethane rubber roller has excellent physical properties, aging resistance, crack resistance, rebound, wear resistance, chemical solvent resistance, compression is not easy to deform, good rebound, long service life; can withstand high pressure, high speed, high temperature, high humidity production environment.
