What ’s PETG?

Do you know PETG? What is its use and application? Let's follow this article to find the answer.

Introduction of PETG 

PET resin is a linear homopolyester formed by the polycondensation of a diol and a dibasic acid. There are PETG, PCTG and PCTA, and degradable copolyester. PETG is a non-crystalline copolyester, which prevents crystallization and improves processing and transparency. Its products are highly transparent and excellent in impact resistance. It is especially suitable for forming thick-walled transparent products. Its processing and forming properties are excellent. It can be designed in any shape according to the designer's intention.

The main uses of PETG 

Building materials

PETG has a wide processing range, high mechanical strength and excellent flexibility. Compared with PVC, it has high transparency, good gloss, easy printing and environmental protection advantages.

By using conventional molding methods, transparent materials with a thickness of 1 to 25.4 mm can be prepared, which has outstanding toughness and high impact strength. Its impact strength is 3 to 10 times that of modified polyacrylates. It does not turn white, has no cracks, and is easy to print and modify. It is widely used in indoor and outdoor signs, storage racks, vending machine panels, furniture, construction and mechanical baffles.

Shaped products

PETG can be formed into various types of pipes. Its products are hard, transparent, and shiny. They are not whitened under pressure, easy to be molded and post-processed. It meets environmental protection requirements and meets FDA food contact standards. It can be used in food and medical treatment. Products and other fields. There are different shapes of plastic packaging, such as IC plastic packaging tube, plastic packaging circular tube, plastic packing circular pipe and tube are widely used in electronic components, precision parts, medical supplies, sports accessories, plastic parts, etc. It improves the low toughness of traditional polyester beverage bottles, and is especially suitable for manufacturing large-capacity thick-walled transparent containers. 

Cosmetic packaging

PETG has the same transparency as glass and a density close to glass, with good gloss, chemical resistance, impact resistance, and easy processing. It can be injection molded, injection stretch blow molded, and extrusion blow molded. It can also produce unique shapes, appearances, and special effects, such as bright colors, matte, marble textures, metallic luster, and more. Moreover, other polyester, elastic plastic or ABS can be used for overmolding.

Products with eco friendly cosmetic packaging include perfume bottles and caps, cosmetic bottles and caps, lipstick tubes, cosmetic boxes, deodorant packaging, talcum powder bottles and eyeliner covers. PETG injection products include medical devices such as filters, Eustachian tubes, tube connectors, pumps, clips, and dialysis equipment. Household utensils such as cups, salad bowls, salt shakers, pepper shakers, etc. These materials have excellent transparency, gloss, good toughness, processability, and excellent colorability. PETG can also be applied in biodegradable food packaging, food packaging containers,cardboard food packaging and so on.
