1. Different definitions: PETG, is a transparent, amorphous copolyester, PETG commonly used copolymer is 1, 4-cyclohexane dimethyl alcohol, known as polyethylene terephthalate -1, 4-cyclohexane dimethyl ester. PET plastic is short for Polyethylene terephthalate, or PET or PETP. Polyterephthalate plastics, mainly including polyethylene terephthalate PET and polybutylene terephthalate PBT.
2. Different uses: PET is mainly used for packaging all kinds of beverage containers, such as gongfu Spring pure water bottles, and cola drinks bottles. Of course, I think PETG is familiar to women who love beauty. PETG is used in cosmetics bottles, perfume bottles, pharmaceutical packaging containers, etc.
3. Different characteristics: PETG plate is easy to produce products with complex modeling and large drawing ratio. Moreover, unlike PC board and impact-modified acrylic, this board does not need to be pre-dried prior to thermal forming. Compared with PC board or acrylic, its molding cycle is short, has a low temperature, higher yield. PET plastic molecular structure is highly symmetrical and has a certain crystal orientation ability, so it has high film forming and characteristics. PET plastic has good optical properties and weather resistance, amorphous PET plastic has good optical transparency.
