Polyester (PET) offers high impact strength, a good fire rating and is suitable for food contact applications, with the exception of the UV grades.
PET is a relatively new thermoplastic sheet material. It can be used as an alternative to Acrylic, Polycarbonate and PVC in many flat sheet applications, but it is not the easiest material to thermoform or hot-wire bend since it can lose its transparency if not processed correctly.
Applications for PET include point of sale displays, price tag holders, shelf partitions, poster glazing, poster boards, food containers and trays, decorative inserts etc. Available in thicknesses from 0.8mm up to 6.0mm.
Copolyester (PETG) (PolyEthylen Terephtalate Glycol modified). PETG is a Glycol modified APET version, which cannot be crystallized as the APET.
The main benefit of this glycol modification is easier processing (thermoforming, welding) that makes it very much easier to process by thermoforming or hot-wire bend. In fact, PETG sheet is one of the easiest of all sheet materials to fabricate.
Unlike PET, PETG can also be successfully solvent bonded. Other properties are similar to PET. Both PET and PETG sheet do not need to be pre-dried before forming.
PETG offers the following features:
- Excellent Impact Resistance
- High Transparency / Shine
- Excellent Fire Resistance
- Food Contact Approved (FDA/BGA)
- Easy To Print – Does Not Require pre-treatment
- Cold & Warm Folds Possible
- Ideal For Medical Applications (can be sterilized)
It offers high impact strength, a good fire rating, are suitable for food contact applications, theroformable and fully recyclable. Available in thicknesses from 0.50mm up to 12.0mm.
