Primary USES of PETG
(1) board and sheet
Using conventional methods of molding, can be prepared 1 ~ 25.4 mm thick transparent material, outstanding toughness and high impact strength, the impact strength is modified polyacrylic ester 3 ~ 10 times, excellent formability, cold bending is not white, no crack, easy to printing and decorate, widely used in indoor and outdoor signs, store content wearing, vending machine panel, furniture, construction and mechanical damper, etc.
The PCTG card is mainly used in Europe, but it is also used more and more in North America and Asia. The reason is that it has a wide range of processing, high mechanical strength and excellent flexibility. Compared with PVC, it is transparent, glossy, easy to print and has environmental advantages.PETG materials are used in credit CARDS. Visa, one of the world's largest credit card companies, issued 580 million CARDS worldwide in 1998. The company has approved glycol modified polyester (PETG) as its credit card material. For countries requiring more environmentally friendly card materials, PETG can replace PVC materials. Visa also notes that results from three different test plants show that PETG meets all requirements of the international credit card standard (150/IEC7810), so PETG CARDS may be widely used here.
(2) different profile
It can be shaped tube material or all kinds of profiles, its products are hard, transparent, shiny, not bleached under pressure, easy to shape and post-processing, in line with environmental protection requirements, and in line with food contact standards of the us FDA, widely used in building decoration and materials.
Film use: it is specially applied in high-performance shrinking film, with 70% ultimate shrinkage of great dry, and can be made into the packaging of complex contour containers. It has the advantages of high plasticity, high transparency, high gloss, low fogging, easy to print, easy to fall off, and low natural shrinkage when stored, which can be applied to beverage bottles, food and chemical. Shrink packaging of ling pin and shrink label of electronic products. Of which two - way stretching. PETG film is suitable for high grade packaging, printing, electronic appliances, cable wrapping, insulation materials and high quality base materials in various industrial fields. Unidirectional stretch PET, heat shrink film applicable to a variety of cans, polyester bottles, containers, and other external labels. Compared with PVC shrink film, PETG shrink film also has the advantages of environmental protection.
Bottle use: improve the deficiency of low toughness of traditional polyester beverage bottle, especially suitable for manufacturing large-capacity thick wall transparent container, highly transparent, not easily broken, easy to surface modification, which can meet the food contact standards of the us FDA, and can be applied in food and medical products and other fields. In terms of beer plastic packaging, EASTMAN company for asahi company production of new environmental protection plastic packaging bottles, is Eastal copolymer polyester film used as packing material, its appearance is silver black, block in the neck ribbon TAB with black hole type, can block the light, cut off the air, ensure the quality of beer, and have in the bottle burst to prevent debris scattered explosion-proof function, superior performance. Sales of Super Dry and Dunk have soared since asahi adopted the packaging material.
(3) cosmetic packaging
PETG has the same transparency as glass and the density close to glass. It has good gloss, chemical resistance, impact resistance, and easy to process. It can also produce unique shapes, appearances and special effects, such as bright colors, sanding, marble textures, metallic luster, and so on. And can also use other polyester, elastic plastic or ABS for overlap injection plastic molding.
Products include bottle and bottle, cosmetic bottle and bottle, lipstick tube, cosmetic box, deodorant pack, powder bottle and eyeliner. PETG injection products include medical instruments such as filters, eustachian tubes, pipe fittings, pumps, clamps and dialysis equipment. Household utensils such as cups, salad bowls, salt and pepper POTS, etc., have excellent transparency, gloss, toughness, processing and coloring
PETG
PETG is a noncrystalline copolyester. During its production, a certain amount of ethylene glycol was replaced by 1, 4-cyclohexane dimethanol(CHDM), which prevented crystallization and thus improved processing and manufacturing and transparency. Its products are highly transparent, excellent impact resistance, especially suitable for thick wall molding transparent products, processing and shaping its excellent performance and can be carried out in accordance with the intention of the designers of any shape design, may adopt the traditional extrusion, injection molding, blow molding, blister, molding method, can be widely used in high-performance shrinkable film, plate, sheet, bottle and profiles etc in the market, at the same time, the second time processing performance is good, can be modified conventional machining
PET resin is linear homogeneous polyester formed by polycondensation of dibasic alcohol (ethylene glycol, EG) and dibasic acid (TPA), while copolymer polyester is a polyester modified by alcohol or acid, including PETG, PCTG and PCTA as well as biodegradable copolymer polyester.
Main features of PETG:
1. Outstanding thermal molding performance
PETG sheet is easy to produce products with complex shape and large tensile ratio. Furthermore, unlike PC board and punching - resistant compression force, this board does not need to be predried before hot forming. Compared with PC board or acrylic force, it has short forming cycle, low temperature and higher yield.
2. The toughness
The extruded sheets of PETG sheets are typically 15 to 20 times tougher than the universal compressive strength and 5 to 10 times tougher than the impact resistant properties. PETG plates have sufficient bearing capacity during processing, transportation and use to help prevent breakage.
3. The weather
The PETG sheet provides excellent weather resistance. It keeps the product tough and prevents it from turning yellow. It contains uv absorbent, can be squeezed together into a protective layer, protecting the plate from the harmful effects of uv.
4. Simple processing
PETG sheet can be cut, die cut, drilling, punching, shearing, riveting, milling and cold bending without breaking. Slight scratches on the surface can be removed with a hot air gun. Solvent bonding is also a routine operation. It is easier to be processed than general strength, anti-impact modified strength or PC board, and can be processed by flocking, electroplating and static electricity.
5. Excellent chemical resistance
PETG sheets are resistant to a variety of chemicals and common cleaning agents.
6. The environmental protection
The base material of PETG plate is environmentally friendly and meets the requirements of food contact management.
Economy 7.
It is cheaper than PC board and more durable than acrylic
