Characteristics: the elastomer of Pu caster has good properties such as abrasion resistance, chemical erosion resistance, high strength, high elasticity, low pressure resistance, strong shock absorption, tear resistance, radiation resistance, high load-bearing, shock absorption and cushioning. PU wheel also has a wide hardness range. In addition, PU wheel has excellent sound absorption characteristics. The wheel does not produce noise during movement, which can achieve the effect of silence. Scope of application It is mainly used in industrial heavy-duty trolley, logistics, storage equipment, heavy machinery supporting equipment and other industries. It is widely used.
