What is petg material
PETG is a kind of transparent plastic, is a kind of amorphous polyester. A total monomer 1, 4 - of PETG Cyclohexane 2 methyl alcohol ( CHDM) , called polyethylene terephthalate 1, 4 - Cyclohexane dimethyl ester. PETG is a kind of amorphous polyester. In the process of production, was 1, 4 - with a certain amount of ethylene glycol Cyclohexane 2 and ( CHDM) To replace, so can prevent crystallization, and can improve the method and transparency. Its products are highly transparent, excellent impact resistance, especially suitable for thick wall molding transparent products. Processing and shaping its good performance. Can design according to the design intent of arbitrary shape. It can be used in a traditional extrusion, injection, blow molding and blister method. Can be widely used in sheet metal, metal plate, high-performance shrinkable film, bottle, profile and other markets. At the same time, the second time the processing performance is good, can be achieved. Conventional processing modification. PETG products with high transparency, good toughness, suitable for forming of thick wall transparent products, PETG processing forming performance, can be designed according to the intention of the designers, can adopt the traditional extrusion, injection molding, blow molding and plastic absorption and modeling method, which can be widely applied in markets such as plate, high-performance shrinkage film, bottle, at the same time, the second time processing performance, can carry on processing and reformation of conventional. Extension data of PETG main use: 1, production plate, sheet, adopt the traditional forming method can thickness of 1 - preparation 25. 4 mm transparent material, has excellent toughness and high impact strength. The impact strength is 3 - modified polyacrylate 10 times. It has excellent formability, cold bending, not white, no crack, printing and modified easily. Widely used in indoor and outdoor signs, shelves and other vending machine panel, furniture, construction and mechanical damper, etc. PCTG card is mainly used in Europe, but in North America, Asia, the application of more and more. The reason is that the processing range, high mechanical strength, good flexibility. Compared with polyvinyl chloride (PVC), it has high transparency, good gloss, easy to printing, environmental protection, etc. 2, the production profiles: pipe forming or various materials, its products quality of a material is solid, transparency, good gloss, compression is not white, easy molding and post-processing, conforms to the requirements of environmental protection, and comply with FDA food contact standards, widely used in architectural decoration and materials. 。 Film: dedicated to high performance shrink film, shrinkage rate over 70%. Can be used to complex container packaging. With high suction plastic, high transparency, high gloss, low degree of fog, easy to printing, not easy to fall off, when storing the natural advantages of low shrinkage rate. Apply to the contraction of beverage bottle, food, cosmetics packaging. Electronic product shrink labels, etc. Bottle with: to improve the traditional polyester beverage bottle low temperature toughness, especially suitable for large capacity of thick wall transparent container manufacturing, highly transparent, is not easy to break, easy to surface modification, accord with standard of American FDA food contact, can be used in food, pharmaceutical products and other fields. 3, production of cosmetics packaging: the transparency of PETG is the same as the glass, close to the glass density, good gloss, resistance to chemical corrosion, impact resistance, easy processing. It can be a injection molding, injection blow molding and extrusion blow molding. It can also produce unique shape, appearance and special effects, such as bright color, grinding, marble texture, metallic luster, and so on. Other polyester, elastic plastic or ABS overlapping can also be used for injection molding.
