| The strength of polyamide-imide is unmatched by any industrial unreinforced plastic in the world. Its tensile strength exceeds 172 MPa, and the heat distortion temperature is 274 ¡ã C under a load of 1.8 MPa. Torlon polymers may also be subjected to solid polymers after manufacture, which provides better performance by post-cure to increase molecular weight. Post-cure occurs at 260 ¡ã C. The time and temperature required for curing depends primarily on the thickness and shape of the part. It can be used for a long time at 260 ¡ã C, without losing weight at 300 ¡ã C. Decomposition begins around 450 ¡ãC. It has better adhesion, flexibility and alkali resistance, can be cross-linked and cured with epoxy resin, and has good wear resistance. The polyamide-imide has excellent mechanical properties, and the tensile strength of the color material is 190 MPa. Molded plastics are mainly used for gear rollers, bearings and copier separation claws. It has good ablation resistance and electromagnetic properties at high temperature and high frequency. It can be used as ablation material, magnetic permeability material and structural material for aircraft. It has good adhesion to metals and other materials and is suitable for use in wire enamels, impregnating varnishes, films, laminates, coatings and adhesives. For example, the enameled wire made with it has been used in the H-class deep-water submersible motor upper plate for printed circuit boards and sockets; the film is used as an insulation wrap material. PAI polyamide-imide (PAI) profiles are fully versatile, proven and proven in both extrusion and molding grades. In high temperature applications, this advanced material combines excellent mechanical properties with exceptional dimensional stability. PAI is a high performance, meltable plastic. It has outstanding high temperature resistance. It can still work at high load pressure and continuous temperature up to 260 ¡ãC. Compared to most advanced engineering plastics, parts made from profiles have higher compressive strength and impact strength. PAI's extremely low linear thermal expansion coefficient and high creep resistance give it excellent dimensional stability. PAI is an amorphous material with a glass transition temperature of 280 ¡ãC. |
