What kind of plastic is PETG?

PETG is a transparent plastic and an amorphous polyester. The common monomer of PETG is 1, 4- cyclohexanedimethanol (CHDM), which is called polyethylene terephthalate-1, 4- cyclohexanedimethanol ester.

PETG is an amorphous polyester. In the production process, a certain amount of ethylene glycol is replaced by 1, 4- cyclohexanediamine (CHD), which can prevent crystallization and improve the manufacturability and transparency. Its product has high transparency and excellent impact resistance, and is especially suitable for molding thick-walled transparent products.

It has excellent processability and can be designed into any shape according to the designer's intention. Traditional molding methods such as extrusion, injection molding, blow molding and plastic absorption can be adopted, which can be widely used in the market of plates, sheets, high-performance shrink films, bottles and special-shaped materials. At the same time, it has excellent secondary processing performance and can be modified by conventional processing.

Extended data

Main uses of PETG:

1, production plate, plate:

Transparent materials with a thickness of 1~25.4mm can be prepared by conventional molding method, which has outstanding toughness and high impact strength. Its impact strength is 3~ 10 times that of modified polyacrylate, and it has excellent formability, no whitening and cracking during cold bending, easy to print and decorate, and is widely used in indoor and outdoor signs, shelves, vending machine panels, furniture and buildings.

PCTG cards are mainly used in Europe, but they are also used more and more in North America and Asia. The reason is that it has a wide processing range, high mechanical strength and good flexibility. Compared with PVC, it has the advantages of high transparency, good luster, easy printing and environmental protection.

2, the production of profiles:

Plastic pipes or various profiles, whose products are hard, transparent, good gloss, non-whitening under pressure, easy to form and post-process, meet the requirements of environmental protection, meet the food contact standards of FDA, and are widely used in architectural decoration and materials.

Application of film: It is specially used for high-performance shrink film, and the shrinkage rate is over 70%, so it can be made into the packaging of complex containers. It has the advantages of high suction, high transparency, high gloss, low haze, easy printing, difficult shedding and small natural shrinkage during storage. Used for shrink packaging of beverage bottles, food, cosmetics and shrink labels of electronic products.

Bottle use: It can improve the problem of low toughness of traditional polyester beverage bottles, and is especially suitable for manufacturing large-capacity thick-walled transparent containers. High transparency, not easy to break, easy to modify the surface, reaching the FDA food contact standard, and can be used in the field of food and medical products.

3, the production of cosmetic packaging:

PETG has the same transparency and density as glass, good luster, chemical corrosion resistance, impact resistance, easy processing, injection molding, injection molding and extrusion molding. You can also make unique shapes, appearances and special effects, such as bright colors, frosting, marble texture, metallic luster and so on. However, other polyesters, elastic plastics or ABS can also be used for overmolding.
