PU Castors

• PU Castors     
• Hardness : shore A 90- Shore D 85  
• High strength  Under rubber hardness, its strength and loading capacity is much better than rubber. Under high hardness, its impact resistance and flexibility are much better than plastic.  
• Excellent anti-abrasion performance  it is about 3-5 times of rubber. 
• Oil resistance  Polyurethane is a strong polar polymer compound。Its affinity with non-polar oil is very slim, so there is almost no erosion in fuel oil and mechanical oil.
• Good elasticity, it could be as buffering or dampers.
• The metal part strongly bonds with PU. It won’t break out. It could also be oil resistance, water-proof or anti-solvent.
