Polyethylene terephthalate (PET), chemical formula (C10H8O4) N, is by dimethyl terephthalate and ethylene glycol ester exchange or to terephthalate and ethylene glycol esterification synthesis of dihydroxyethyl terephthalate, and then the condensation reaction. Is a crystalline saturated polyester, milky white or light yellow, highly crystalline polymer, smooth and shiny surface, is a common resin in life, can be divided into APET, RPET and PETG.
In a wide temperature range with excellent physical and mechanical properties, long-term use temperature up to 120ºC, excellent electrical insulation, even at high temperature and high frequency, its electrical properties are still good, but the corona resistance is poor, creep resistance, fatigue resistance, friction resistance, dimensional stability is very good.

PET Resin is cream or pale-yellow crystal, with smooth and shiny surface. Resistance to creep deformation, fatigue resistance, abrasion resistance and dimensional stability are perfect. Small wear and tear but high hardness, its toughness is the largest in thermoplastic. The electrical insulation of PET is perfect and little be affected by temperature, however, poor corona resistance. PET is non-toxic, weather resistance, and anti-chemical stability is very good. PET is low water absorption, resistance to weak acids and organic solvents. Intolerance of hot water immersion and alkali.
Feature:
1.Oil resistant, fat resistant, acid resistant, alkali resistant, resistant to most solvents.
2.Excellent resistance performance of high and low temperature.
3.Non-toxic, tasteless, health and safety.
4.Transparent, UV blocking, good glossiness
