What is the difference between PET and PETG?
PET (polyethylene terephthalate)
Polyethylene terephthalate (PETG) is a crystalline polyester.
PETG (ethylene glycol modified polyethylene terephthalate)
PETG is modified by adding ethylene glycol to prevent partial crystallization, making it softer and easier to process.
1. Environmental performance: PET and PETG are both recyclable environmentally friendly new materials.
2. Production process: Our PET is a two-way stretch PET (BOPET), which adopts a two-way stretch production process; while PETG is extruded and coated, so PET has better scratch resistance.
3. Our PET is a two-way stretch PET (BOPET). PET is stretched vertically and horizontally during the production process, and its scratch resistance is slightly better than that of PETG. PETG is stretched and extruded longitudinally before coating. PETG adopts a three-layer GAG structure, so it can better control the color difference.
4. Application: Our PET is usually processed into a transparent film with a hardness of 3-4H, and PETG is processed into a color film. The chromatic aberration control rate between different batches can reach ΔE<1, and there is almost no chromatic aberration.
