Special urethane elastomer materials

polyurethane is one of the six synthetic materials in the world, of which polyurethane elastomers have been widely used in metallurgy, drilling, shoemaking and chemical fiber machinery due to their unique propertiesHowever, due to the poor heat resistance and endogenous heat, polyurethanes have limited their application in some special areasForeign countries have done a lot of work in its development, and there are many commercial productsIn contrast, domestic development is relatively backward, nearly blank, still need to import a large number of polyurethane products with special properties each yearthe Shanxi Institute of Coal Chemistry of the Chinese Academy of Sciences has accumulated a lot of experience in the field of polyurethane research and development over the yearsThe institute's researchers have developed functional-enhanced special urethane products by introducing heat-resistant organic heterocyclic compounds into the polymer molecular chain structure, improving microphase separation and adding inorganic fillers (whiskey, fiber, nanomaterials)Compared with ordinary polyurethane elastomers, these special urethane products, while maintaining the original excellent comprehensive performance, especially highlight certain properties such as high hardness, high strength, heat resistance, solvent resistance, etcto adapt to the requirements of special applicationssuch as the development of special polyurethane elastomer temperature resistance has been improved, the use of temperature from 80 degrees C to 130 degrees C, the current polyurethane elastomer has been successfully applied to oil field drilling drill pipe anti-grinding sleeve, high-pressure sealing ring and textile machinery, growth wheel, friction plate, etc., to fill the domestic blank
