What Material Is PET？
Jun 28, 2022
1.Pet is commonly known as polyester resin, also known as polyethylene terephthalate, which is the most important variety in thermoplastic polyester. It is a polycondensate of terephthalic acid and ethylene glycol. Thermoplastic polyester or saturated polyester.
2.Pet is a milky white or light* highly crystalline polymer, its surface is smooth and shiny, characterized by creep resistance, fatigue resistance, friction resistance and good dimensional stability, etc.
3.Pet has the best toughness among thermoplastics, that is, it has good electrical insulation performance and is less affected by temperature, but has poor corona resistance. It is non-toxic, has weather resistance, good chemical resistance, good stability, and water absorption. Low rate, resistant to weak acids and organic solvents, but not resistant to hot water immersion and alkali.
4. The glass transition temperature of pet resin is relatively high, the crystallization speed is slow, the molding cycle is long, the molding cycle is long, the molding shrinkage rate is large, the dimensional stability is relatively poor, the crystallization molding is brittle, and the heat resistance is low.
