High Transparent Plastic PETG Sheet for Thermoforming

PETG is a non-crystalline PET resin modified with cyclohexanediol. The performance of PETG is very different from PET and PCT. PETG is an amorphous copolyester. With the increase of CHDM (cyclohexane dimethanol) in the copolymer, the melting point decreases, the glass transition temperature increases, and the crystallinity decreases to form an amorphous polymer. Generally, the content of CHDM in PETG is 30% to 40%. Has excellent optical properties (high light transmission, high smoothness and low halo), has outstanding toughness and impact performance, its impact strength is 3 to 10 times that of modified polyacrylate, excellent molding performance, cold bending is not universal White, no cracks, good sanitation (compliant with FDA), easy to print and modify, can also be processed by various plastic molding, and made into various electronic product packaging materials. PETG sheet is widely used in indoor and outdoor signs, point-of-sale displays, store shelves, game machine panels, vending machine panels, food containers, furniture, construction and mechanical baffles. PETG is a highly transparent engineering plastic, which belongs to a new generation of environmentally friendly plastics.

The main characteristics of PETG

· Excellent thermoforming performance
PETG sheet is easy to produce products with complex shapes and large draw ratios. Unlike PC board and impact-modified acrylic, this board does not require pre-drying before thermoforming. Compared with PC board or acrylic, its molding cycle is shorter, the temperature is lower, and the yield is higher.
· Toughness
The extruded sheet of PETG sheet is generally 15 to 20 times tougher than general-purpose acrylic and 5 to 10 times tougher than impact-resistant acrylic. PETG sheet has sufficient bearing capacity during processing, transportation and use, and is not easy to crack.
· Weather resistance
PETG sheet provides weather resistance. It keeps the product tough and prevents yellowing. It contains a UV absorber that can be co-extruded into a protective layer that protects the board from the harmful effects of UV rays.
· Easy processing
PETG sheet can be sawed, die-cut, drilled, punched, cut, riveted, milled and cold-formed 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 process than general-purpose acrylic, impact modified acrylic or PC board, and can be processed by flocking, electroplating, static electricity and so on.
· Chemical resistance
PETG sheet can withstand many chemicals and commonly used cleaning agents.
· Environmental protection

PETG board substrates are all environmentally friendly materials and meet food contact management requirements.
