Gwell Machinery is a high-tech enterprise, committed to providing customers with plastic sheet, board, film and other extrusion lines. Gwell can provide turnkey projects, such as stone paper project, EVA solar film project, PP building formwork equipment,etc. Gwell has a strong technical equipment strength and key capacity, committed to high-end product development, international market development. “Realize customer value" is the company's long-term business philosophy.The manufacturing bases of the company are located in Taicang, Suzhou, which is close to the beautiful scenery of Shanghai, Yancheng Dafeng, the hometown of Red-crowned crane, and Nantong, the hometown of Education and longevity in China. It covers a total area about 150,000 square meters. It has an annual production capacity of more than 200 extrusion lines of various types of sheet and board.
2. Introduction of PETG material and board PETG, the full English name Poly (ethylene terephthalate-1, 4-cylclohexylenedimethylene terephthalate), is a transparent, non-crystalline copolyester. The performance of PETG is not the same as PET.
PETG sheet has outstanding toughness and high impact strength. Its impact strength is 3-10 times that of modified polyacrylates. Compared with APET, it has a wide processing range, high mechanical strength excellent flexibility, high transparency, good gloss, easy printing and environmental protection.
While PETG sheet has the characteristics of APET sheet, its major features are outstanding heat sealing performance, easy operation during sealing and reliable heat sealing quality. Compared with APET, PETG won't be crystallized even under a very high molding temperature.For vacuum forming, even clear contours of complex geometric shapes can be obtained. However, due to its relatively high price, the application is subject to certain restrictions.
The chemical stability of PETG is the same as that of APET.
3. Main Features of PETG sheet/board
(1) Chemical resistance
PETG sheet can withstand a variety of chemicals and commonly used cleaning agents.
(2) Environmental friendly
The PETG sheet substrates are all environmentally friendly materials, which meet the requirements of food contact management.
(3) Economy
It is cheaper than PC board and more durable than acrylic.
Thermoformability PETG sheets are easy to produce products with complex shapes and large stretch ratios. Moreover, unlike PC board and impact-modified acrylic, this board does not need to be pre-dried before thermoforming. Compared with PC board or acrylic, its molding cycle is short, the temperature is low, and the yield is higher.
(4) Toughness
The extruded sheet of PETG sheet is usually 15 to 20 times tougher than general acrylic and 5 to 10 times tougher than impact modified acrylic. PETG sheet has sufficient bearing capacity during processing, transportation and use, which helps prevent cracking.
(5) Weather resistance
PETG sheet provides excellent weather resistance. It can maintain the toughness of the product and prevent yellowing. It contains ultraviolet absorbers, which can be co-extruded into a protective layer to protect the board from the harmful effects of ultraviolet rays.
(6) Easy to process
PETG sheet can be sawed, die-cut, drilled, punched, sheared, riveted, milled and cold-formed without breaking. Slight scratches on the surface can be eliminated with a hot air gun. Solvent bonding is also a normal operation. It is easier to process than general acrylic, impact modified acrylic or PC board, and can be processed for flocking, electroplating, static electricity and other processing.
