Polyurethane wheels Benefits:
1, polyurethane wheels processing methods varied, broad applicability. Polyurethane wheels with universal rubber elastomer can use as mastication, mixing, curing molding process; also be made of liquid rubber pellets can also be made with ordinary plastic, as by injection, extrusion, calendering, blow molding and other molding process. Molding or injection molded parts, within a certain range of hardness, but also can be cut, grinding, drilling and other machining. Processing of diversity, the applicability of the polyurethane elastomer is very extensive, applications continue to expand.
2, oil resistance, ozone resistance, aging resistance, radiation resistance, low temperature, transparent sound good, strong adhesion, excellent biocompatibility and blood compatibility. It is these advantages of polyurethane elastomer widely used in military, aerospace, acoustics, biology and other reasons.
3, the performance can be adjusted range. A number of physical and mechanical performance indicators can be selected and adjusted by the formulation of raw materials, changes within a certain range to meet the different requirements of users of the product properties.
4, superior wear resistance. Particularly where there is water, oil wetting medium existing working conditions, the wear resistance is often several times to several times the ordinary rubber materials. Metallic materials such as steel, although very hard, but not necessarily wear, while the use of polyurethane elastomer coated round orifice ring and the protection ring 1800 consecutive run into yet little wear.

    Due to the excellent performance elastomeric polyurethane wheels and extensive use of polyurethane elastomer body study abroad in the ascendant, and constantly improve the polyurethane elastomer processing and application performance through technical means.
1, the high thermal stability of polyurethane elastomer. Domestic dawn Chemical Research Institute and other units for the poor performance of the polyurethane elastomer temperature and other shortcomings easy hydrolysis, by improving the elastomer molecules crosslink density, improve micro-phase separation and selection of the isocyanate and chain extender agent of raw materials to improve the properties of the polyurethane elastomer , also by the addition of an antioxidant, a heat stabilizer, and some fillers to improve thermal stability of polyurethane elastomer.
2, the antistatic polyurethane elastomer. Many applications, especially some of the newly developed electronics, medical, automotive, packaging and other industries for antistatic high demand, so antistatic polyurethane elastomer development has become an important direction of development. Domestic research institutions by adding a cationic antistatic agent, carbon black filled, means a metallic material, metal fibers, and hydrophilic polymers or intrinsically conductive polymer blends and other prepared antistatic polyurethane elastomer.
