Problems solved by technology

Since polyethylene terephthalate has the characteristics of crystallinity and high temperature resistance, the molding compound produced by it has good temperature resistance and ideal strength, but due to high crystallinity, the product shrinkage is large, resulting in Product deformation is its lack,
[0003] With the continuous improvement of the level of science and technology, the quality, flame retardancy, high temperature resistance, mechanical strength, hardness and other aspects of the existing polyethylene terephthalate plastics for heaters have gradually been unable to meet the needs of the product. The production cost of the product seriously restricts the development of polyethylene terephthalate

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a high-temperature-resistant modified polyethylene terephthalate. Background technique [0002] Polyethylene terephthalate is a milky white or light yellow, highly crystalline polymer with a smooth and shiny surface. It has excellent physical and mechanical properties in a wide temperature range. The long-term use temperature can reach 120 ° C. It has excellent electrical insulation. Even at high temperature and high frequency, its electrical properties are still good, but its corona resistance is poor. Creep resistance, fatigue resistance, friction resistance and dimensional stability are all very good. Because polyethylene terephthalate has the characteristics of crystallinity and high temperature resistance, the molding compound produced by it has good temperature resistance and ideal strength, but due to high crystallinity, the product shrinkage is large, resulting in Produ...
