What material is PETG?
Among the hot topics in the past 10 days, PETG, as a high-performance plastic material, has received widespread attention due to its environmental protection and wide range of application fields. This article will introduce in detail the definition, characteristics, application scenarios and market data of PETG to help readers fully understand this material.
1. Definition of PETG
PETG (Polyethylene Terephthalate Glycol) is an amorphous copolyester material, which is modified from PET (polyethylene terephthalate) by adding cyclohexanedimethanol (CHDM). This modification makes PETG combine high transparency, high toughness and easy processability, making it a popular material in the plastics industry in recent years.
2. Characteristics of PETG
PETG has the following salient properties that make it stand out in multiple fields:
| Features | Description |
|---|---|
| Transparency | Up to more than 90%, close to the light transmittance of glass |
| Resilience | Excellent impact resistance and not easy to break |
| chemical resistance | Good resistance to most chemical solvents and oils |
| Environmental protection | Recyclable and meets environmental protection requirements |
| Processing performance | Easy to thermoform, cut and bond |
3. Application scenarios of PETG
Due to its excellent performance, PETG is widely used in the following fields:
| Application areas | Specific use |
|---|---|
| Packaging industry | Food packaging, cosmetic bottles, pharmaceutical containers, etc. |
