10 advantages of heavy duty polyurethane casters
Heavy duty polyurethane plastic is widely used in heavy duty casters. Many manufacturers use this material in their products. It is a thermoplastic polyurethane elastomer with light weight, impact resistance, wear resistance and corrosion resistance made by pouring production process.
Why did you choose this material? Because it has some unique features:
1. Good wear resistance, 5-8 times that of nitrile butadiene rubber;
2. Good bending strength, good elasticity;
3.Tensile strength and fracture elongation;
4. Strong tear resistance;
5.Moderate temperature resistance (-50℃ ~ 85℃) up to 120℃;
6.Oil resistance, water resistance, mildew resistance, good solvent resistance;
7. Good aging resistance;
8.Hardness adjustable range (Shao 15A ~ 98A);
9.Compression permanent deformation rate is low;
10. The bearing capacity of cast iron polyurethane casters is relatively large.
Of course, this material also has certain limitations, in some special types of universal wheel can not be used, but in general, this material can be widely used.
