What is PETG material? What are the applications?

PETG is a transparent and amorphous copolyester. Compared with PET, there are more 1,4-cyclohexanedimethyl alcohol copolymers and more ethylene glycol copolymers than PCT. Therefore, the properties of PETG are quite different from those of PET and PCT. PETG sheet has outstanding toughness and high impact strength. Its impact strength is 3-10 times that of modified polyacrylates. It has a wide processing range, high mechanical strength and excellent flexibility.
PETG has the same transparency as glass and close to the density of glass. It is easy to process and can be injected, drawn and extruded. It can also produce unique shape, appearance and special effects. Other polyesters, elastic plastics or ABS can also be used for overlapping injection moulding. The order of temperature resistance with other materials is PC > PP > PMMA > ABS > HIPS > PETG > PVC > PE.
Scope of application, for example
1. Plates and sheets: Because of their outstanding toughness, high resistance and excellent formability, cold bending without white cracks, easy printing and decoration, they are widely used in indoor signs, storage shelves, vending machines, etc.
At present, PETG cards and credit cards are mainly used in Europe. They are also used more and more in North America and Asia. For countries requiring more environmentally friendly card materials, PETG may be a substitute for PVC materials. Like the second generation ID card, it's made of PETG film.
2.Pipe material: Because of the good toughness of PETG, the product is hard, transparent, glossy, not white under pressure, easy to form and post-processing. It is widely used in building decoration and materials.
3.Membrane: PETG can be specially applied to high-performance shrinkage film with a final shrinkage rate of more than 70%. It can be packaged into complex containers with high plastic absorption, high transparency and high gloss. The advantages of low natural shrinkage in storage are applied to shrinkage labels of beverage bottles, food, gift packaging and electronic products.
4. Bottle use: PETG has passed the FDA standards on food contact. It can be used to improve the low toughness of traditional polyester beverage bottles. It is highly transparent and not easy to break. It can block light, isolate air, ensure the quality of drinks, and has the explosion-proof function of preventing splashing debris when the bottle body breaks. Especially suitable for manufacturing large capacity thick wall transparent containers, such as beer bottles.
Now Vanky Pack has used PETG to make a variety of cosmetic packaging materials.
