【 Pu castor 】 Why have a pu castor castor? Polyurethane (pu) commonly known as optimal force glue, rubber spring, called: carbamic acid polyester or polymer isocyanate resin. Polyurethane is a kind of between plastic and rubber elastomer, its good comprehensive performance is common plastic and rubber. Polyurethane wheel polyurethane wheel according to the features of elastomer with good wear resistance, resistance to chemical attack, high strength, high elasticity, strong resistance to low pressure, shock absorption, tear resistance, radiation resistance, high load and shock absorption, etc. Good performance. Polyurethane wheels at the same time have a wide range of hardness, from shaw A10 & ndash; 100. Currently on the market has been beyond the shaw A100 or above products. In addition, the superior sound-absorbing properties of the polyurethane wheel, the wheels in motion process does not produce noise, can be silent. These characteristics of PU wheel, very suitable for as castor material. Polyurethane wheels can adopt many kinds of processing methods ( 1) , polyurethane wheels can be like common plastic, use process such as injection, extrusion, calendering, blow molding, The CPU) ; ( 2) With general rubber, polyurethane elastomer can take plasticate, mixing and vulcanization process molding ( The MPU) ; ( 3) , polyurethane wheel can also be made into liquid rubber, mould pressing or spraying, sealing, centrifugal casting molding ( The CPU) 。 【 Pu castor 】 Why have a pu castor castor? 新闻/ 126。 html
