Physical properties Excellent wear resistance Strong PU material has excellent wear resistance, its wear resistance is several times that of ordinary rubber. This feature makes products made of PU, such as soles, tires, etc., able to maintain a good condition during long-term use and friction, extending the service life of the product. The elasticity of PU is very prominent, the tensile strength is high, and it can be stretched to several times the original length and quickly restored to the original state. This high elasticity makes PU material suitable for a variety of products that need good elasticity, such as sports shoes, sofas, mattresses, etc., which can provide good cushioning and support and improve the comfort of the product. Soft and comfortable PU material feels soft, and can bring a comfortable touch when in contact with human skin. This feature makes PU widely used in clothing, household goods and other fields, such as the production of underwear, home wear, sofa cushions, etc., to provide people with comfortable wearing and use experience. Second, stable chemical properties and good oil resistance PU has strong resistance to oil substances and is not easy to be eroded by oil substances. This advantage makes PU material perform well in applications in automotive, machinery and other fields, such as for making automotive interiors, seals and other products, which can maintain stable performance in the oil pollution environment for a long time. Good solvent resistance PU has good tolerance to many common solvents, such as alcohols, esters, ketones, etc. This makes PU material in contact with these solvents, will not be as easy as some other materials to dissolve, expand and other phenomena, to ensure the structure and performance of the product is stable. PU material has good anti-aging performance and can be used for a long time under harsh environmental conditions without aging. Whether in high temperature, low temperature or wet environment, PU can maintain good physical and chemical properties, extending the service life of the product. Third, good air permeability Good air permeability PU material has a certain permeability, can allow air circulation, help heat dissipation and keep dry. This feature is particularly important in areas such as clothing and footwear to improve comfort and reduce discomfort caused by heat and humidity. Good moisture permeability PU can effectively discharge water vapor through the material to keep the interior dry. This function makes PU material widely used in sports clothing, outdoor goods and other fields, can help the human body to keep dry, improve the comfort and safety of sports. Fourth, good appearance and processing performance Beautiful appearance PU material can be made into various colors and textures of products through different formulas and processes to meet the needs of different consumers. Its surface can show a smooth, delicate effect, but also can simulate the texture of different materials such as leather, with high aesthetics. The processing performance of PU is good, and products of various shapes and sizes can be made by injection, extrusion, calendering and other processes. This allows PU materials to meet the needs of different fields of application, providing more flexibility for product design and manufacturing.
