PETG, also known as Poly (ethylene terephthalate co-1,4-cyclohexylene terephthalate), is a kind of transparent, amorphous copolyester.
The commonly-used comonomer for PETG is 1,4-cyclohexanedimethanol (CHDM), which is also known as polyethylene terephthalate 1,4-cyclohexanedimethanol ester. It is a product of ester exchange polymerization of three monomers, terephthalic acid (PTA), ethylene glycol (EG), and 1,4-cyclohexanedimethanol (CHDM), with more 1,4-cyclohexanedimethanol comonomers compared to PET and more ethylene glycol comonomers compared to PCT. Therefore, the performance of PETG is significantly different from that of PET and PCT. PETG has outstanding toughness and high impact strength, with an impact strength of 3-10 times that of modified polyacrylates. It has a wide processing range, high mechanical strength, and good flexibility. In addition, PETG has higher transparency and better gloss, and is easier to print,compared to PVC.
Introduction of the Main Advantages of PETG
|
Advantages |
Description |
|
Outstanding hot-forming performance |
It is easy to use PETG to produce products with complex shapes and high stretching ratios. In addition, compared to PC materials or acrylic, it has shorter forming cycles, lower temperatures, higher yield, and does not require pre-drying treatment before hot forming processing. |
|
Excellent chemical resistance |
PETG can withstand various chemicals and commonly-used cleaning agents. |
|
Weather resistance |
PETG has excellent weather resistance. It can maintain the toughness of the product and prevent yellowing; It contains ultraviolet absorbers that can be extruded into a protective layer to protect the board from the influence of ultraviolet rays. |
|
Environmental protection performance |
PETG substrates are all environmental-friendly materials that comply with food contact management requirements. |
|
Economic performance |
It is cheaper than PC boards and more durable than acrylic. |
|
Easy to process |
PETG can be sawn, die-cut, drilled, punched, sheared, riveted, milled, and cold bent without breaking, and slight scratches on the surface can also be eliminated with a hot air gun. It is easier to process than general acrylic, impact resistant modified acrylic, or PC board. |
