What is the difference between PET and PETG?

1、Different definitions
PETG, a transparent, non-crystalline copolyester, PETG commonly used copolymer monomer for 1,4-cyclohexylenedimethylene (CHDM, Cylclohexylenedimethylene), the full name of polyethylene terephthalate-1,4-cyclohexanedimethanol ester.
PET plastic is the abbreviation of Polyethyleneterephthalate (PET or PETP), which means: polyethylene terephthalate plastic, mainly including polyethylene terephthalate PET and polybutylene terephthalate PBT.

2、Different uses
PET is mainly used in the packaging of various beverage containers, such as the pure water bottles like Farmer's Spring and Coke like beverage bottles. Of course I think women who love beauty should not be unfamiliar with petg.
PETG is used for all kinds of long-lasting daily necessities, such as cosmetic bottles, perfume bottles, pharmaceutical packaging containers, etc.

3、Different characteristics
PETG sheet is easy to produce products with complex shape and large stretch ratio. Moreover, unlike PC sheet and impact modified acrylic, this sheet does not require pre-drying treatment before thermoforming processing. Compared with PC sheet or acrylic, the molding cycle time is shorter, the temperature is lower, and the yield is higher.
PET plastic molecular structure is highly symmetrical, has a certain crystalline orientation ability, so it has a high film-forming and into the sexual. PET plastic has good optical properties and weather resistance, amorphous PET plastic has good optical transparency.
