Problems solved by technology

[0002] Polyethylene terephthalate (PET) is a crystalline polymer with high melting temperature and glass transition temperature, which maintains excellent physical and mechanical properties in a certain temperature range, and its fatigue resistance , friction resistance, aging resistance, and electrical insulation are extremely prominent, relatively stable to most organic solvents and acids, and have low production energy consumption, so they are widely used in the fields of synthetic fibers, films, and engineering plastics; but because PET Strong rigidity leads to poor toughness of the material, slow crystallization speed, high mold temperature and long molding cycle, etc., which greatly limit its application range
Polytrimethylene terephthalate (PTT) is a crystalline polymer with fast crystallization speed, low melting temperature and glass transition temperature. It has particularly excellent softness, elastic recovery, processability, electrical properties, and mechanical properties. and dimensional stability; however, PTT has defects such as low notched impact strength, high notch sensitivity, low dimensional stability, poor heat resistance, and poor flame retardancy, which will limit its application field
