Liaoyang Petrochemical PETG LH690T

A non-crystalline copolyester, as the amount of CHDM in the copolymer increases, the melting point decreases, the glass transition temperature rises, and the crystallinity decreases, eventually forming an amorphous polymer. Generally, a CHDM content of 30%-40% in PETG is most suitable. It has good adhesion, transparency, color retention, chemical resistance, and resistance to stress whitening. It can be quickly thermoformed or extrusion blow molded. Its viscosity is better than acrylic (PMMA). The products made from it are highly transparent with excellent impact resistance, making it particularly suitable for thick-walled transparent products. It has excellent processing properties, allowing for arbitrary shape design according to the designer's intent. Traditional extrusion, injection molding, blow molding, and thermoforming methods can be used. It can be widely applied in sheet materials, high-performance shrink films, bottles, profiles, and other markets. Its secondary processing performance is also excellent, allowing for conventional machining modifications. PETG is an amorphous copolyester, whose products are highly transparent and have excellent impact resistance, making it particularly suitable for thick-walled transparent products. It has excellent processing properties, allowing for arbitrary shape design according to the designer's intent. Traditional extrusion, injection molding, blow molding, and thermoforming methods can be used. It can be widely applied in sheet materials, high-performance shrink films, bottles, profiles, cosmetics packaging, and other markets. Its secondary processing performance is also excellent, allowing for conventional machining modifications. Domestic major agents for products like Eastman PETG and SK PETG include Shanghai Lianmo Chemical, among others. PET resin is produced by polycondensation of diols (ethylene glycol, EG) and dicarboxylic acids (terephthalic acid, TPA) into linear homopolymers, while copolyesters are polyester modified with alcohols or acids, including types such as PETG, PCTG, PCTA, and biodegradable copolyesters. PETG is a non-crystalline copolyester. During its production, a certain amount of ethylene glycol is replaced by 1,4-cyclohexane dimethanol (CHDM), preventing crystallization and improving manufacturability and transparency. Its products are highly transparent and have excellent impact resistance, making them particularly suitable for thick-walled transparent products.

Its secondary processing performance is also excellent, allowing for conventional machining modifications. Key Features: - **Thermoformability**: PETG sheets can easily produce complex and highly stretched products. Unlike PC sheets and impact-modified acrylics, these sheets do not require pre-drying before thermoforming. Compared to PC or acrylic sheets, they have shorter cycle times, lower temperatures, and higher yields. - **Toughness**: Extruded PETG sheets are typically 15 to 20 times tougher than general-purpose acrylic and 5 to 10 times tougher than impact-modified acrylic. This ensures sufficient durability during processing, transportation, and use, helping to prevent breakage. - **Weather Resistance**: PETG sheets offer excellent weather resistance. They maintain toughness and prevent yellowing. Containing UV absorbers, they can be co-extruded into a protective layer, protecting the sheets from harmful UV effects. - **Processing Ease**: PETG sheets can be sawed, die-cut, drilled, punched, sheared, riveted, milled, and cold-bent without breaking. Minor surface scratches can be removed using a heat gun. Solvent bonding is also a common operation. It is easier to process compared to general-purpose acrylic, impact-modified acrylic, or PC sheets, and can undergo flocking, electroplating, static processing, etc. - **Chemical Resistance**: PETG sheets can withstand various chemicals and common cleaning agents. - **Environmental Friendliness**: PETG sheets are made from environmentally friendly materials that meet food contact management requirements. It is cheaper than PC sheets and more durable than acrylic. Main Applications: - Sheets and Films: Using conventional forming methods, transparent materials 1 to 25.4 mm thick can be prepared. These materials have outstanding toughness and high impact strength, which is 3 to 10 times that of modified polymethyl methacrylate. They have excellent forming properties, do not turn white when cold-bent, and do not crack. They are easy to print and modify, widely used in indoor and outdoor signs, storage racks, vending machine panels, furniture, building and mechanical barriers, etc. - PETG Cards: Mainly used in Europe but gaining increasing application in North America and Asia due to their wide processing range, high mechanical strength, and excellent flexibility. Compared to PVC, they offer higher transparency, better gloss, ease of printing, and environmental advantages.
