What are the main advantages of polyurethane wheel1. Large adjustable range of performance. A number of physical and mechanical performance indicators can be adjusted through the selection of raw materials and formula, in a certain range of changes, so as to meet the user's different requirements for product performance.2, excellent wear resistance. Especially in the presence of water, oil and other wetting medium working conditions, its wear resistance is often several times to dozens of ordinary rubber materials. Metal materials, such as steel, are hard but not necessarily wear-resistant. However, the mouth ring and protective ring covered by polyurethane wheel elastomer are still not worn after continuous operation of 1800 hours.3. Various processing methods and wide applicability. Polyurethane wheel elastomer can be formed by plastic refining, mixing and vulcanization process as general rubber. Can also be made of liquid rubber, can also be made of granular materials, and ordinary plastic, with injection, extrusion, calendered, blow molding and other processes. Molding or injection molding parts, in a certain range of hardness, can also be cut, grinding, drilling and other mechanical processing. Due to the diversity of processing, polyurethane elastomers have a wide range of applicability and applications.4. Oil resistance, ozone resistance, aging resistance, radiation resistance, low temperature resistance, good sound transmission, strong adhesion, excellent biocompatibility and blood compatibility. These advantages are the reason why polyurethane elastomers are widely used in military industry, aerospace, acoustics, biology and other fields.
