PET Plastic



PET is an opalescent or light yellow highly crystalline polymer with smooth and glossy surface. It has good creep resistance, fatigue resistance, friction resistance, low wear and high hardness, and has the largest toughness in thermoplastic plastics; it has good electrical insulation performance, little influence by temperature, but poor corona resistance. Non toxic, weather resistant, chemical resistant, good stability, high moisture absorption, drying before molding is necessary. It is resistant to weak acids and organic solvents, but not to hot water immersion and alkali.

The molecular structure of pet plastics is highly symmetrical, and it has a certain ability of crystal orientation, so it has high film-forming and forming properties. Pet plastics have good optical properties and weatherability. Amorphous pet plastics have good optical transparency. In addition, pet plastics have excellent wear resistance, friction, dimensional stability and electrical insulation. PET bottles are widely used because of their high strength, good transparency, non-toxic, impermeable, light weight and high production efficiency.
