PETG Resin

PETG Resin is a transparent, non-crystalline copolyester and a thermoplastic PET polymer. PETG resin is a copolymerized product obtained by replacing part of ethylene glycol with other glycols (copolymerization monomer) during synthesis. According to the different proportions of CHDM, the copolyester with more than 50% CHDM is called PCTG, and the copolyester with less than 50% CHDM is called PETG.

Our PETG Resin is produced by replacing a portion of ethylene glycol (MEG) with neopentyl glycol (NPG). For more information, please click https://www.polyestermfg.com/petg-chip/. 

FEATURES

Durability and Impact Resistance
PETG polymer has excellent durability and impact resistance and can remain intact for long periods in high-strength, high-pressure environments. This makes it a suitable material for manufacturing architectural decorative panels, including wall panels, ceilings, partitions, doors, windows, and so on.

High Transparency
PETG material has excellent transparency and light transmittance. Its sheets can be used to make transparent roofs, skylights, partitions, and other structures to bring more natural light indoors.

Fire Resistance
PETG has a high flame-retardant rating and can reach a B1 or higher fire rating. Its decorative panels are widely used in commercial, residential, medical, and public facilities, as well as other fields.

Processability
PETG has good processability. It can be molded and processed in various ways and customized to meet different architectural needs.

Environmental Protection
PETG is a recyclable material that can help reduce environmental pollution and resource waste during recycling and reclamation. Meanwhile, it can also be incinerated without producing harmful substances.

Safety
PETG material will not release harmful substances during use, will not deform under heat, and will not produce toxic gases. Therefore, it is well-suited for use in the construction industry.

Economic
PETG has relatively low manufacturing costs and is easy to process and mold, making it economical and sustainable for construction applications.

In addition to the above characteristics, PETG resin has strong plasticity and flexibility. In addition, PETG materials can be dyed, printed, laminated, and processed to meet a wide range of needs.

Although PETG material has many advantages, it also has some disadvantages. For example, it is not hard enough and scratches easily, which requires attention to maintenance. In addition, it is not strong enough to withstand heavier loads.

Applications

Heat-shrinkable Film
Heat-shrink polyester film is commonly used in convenience food and beverage markets, electronic and electrical appliances, and metal products; shrink labeling is its most important application. Due to growing public concern about environmental protection, local governments are promoting the use of PETG instead of PVC for manufacturing heat-shrinkable film. Well-known domestic and international beverage factories are installing new beverage production lines that use PETG heat-shrinkable film for outer labeling. In the last 10 years, the annual demand for PETG heat-shrinkable film in mainland China has grown by more than 10%.

 

 

 

 

 

 

 

 

 

 

 

 

Optical Film
Optical films are used everywhere, from eyeglass coatings to cell phones, computers, TVs, LCDs, and LED lighting. PETG optical protection film adopts high-end coating technology, with a high-hardness outer surface, scratch resistance, anti-reflectivity, anti-glare, self-cleaning, and non-residual adhesive, among other special features. It can protect the surfaces of various electronic products, such as cell phones, tablets, computers, display screens, and car visual equipment.

Heat-sealing film
Ordinary PET is a crystalline polymer; after stretching and orientation, it can achieve a significant degree of crystallization. For example, when used for heat sealing, it causes shrinkage and deformation, so ordinary PET film lacks heat-sealing performance.
To address heat-sealing issues, we modified the PET resin and used the A/B/C three-layer die structure to develop a three-layer co-extruded heat-sealable PET film. Because the heat-sealable layer has a side, it can be heat-sealed directly, making it very convenient to use.

To sum up, PETG resin offers excellent transparency, chemical resistance, impact resistance, and easy processing. It is widely used in construction, medical, industrial, and other fields, replacing traditional PMMA, PVC, polycarbonate (PC), and other materials. It has become one of the most popular building materials on the market. PETG materials are commonly found in the form of sheets, tubes, rods, films, etc., of which the most common forms are sheets.
