PETG's Bright Future: Transforming the Thermoplastic Landscape


Polyethylene terephthalate glycol, or PETG, is a transparent copolyester with excellent development potential as a thermoplastic material.

1.     What is PETG?

Transparent thermoplastic with exceptional chemical and physical properties is PETG (polyethylene terephthalate glycol). It is a modified form of PET (Polyethylene Terephthalate) that has glycol structures added to the molecular chain to increase toughness, ductility, and heat resistance. PETG is a material with good electrical insulation qualities, low water absorption, wear resistance, gloss, and chemical corrosion resistance.


2. PETG material offers a lot of great qualities.

The following characteristics of PETG (Polyethylene Terephthalate Glycol), a transparent and amorphous copolyester, are present:

1) High transparency: Products have a pleasing visual effect thanks to PETG's outstanding transparency and high gloss.

2) Outstanding resilience to impact and durability: PETG demonstrates exceptional resilience to impact and durability, remaining intact in high-intensity and high-pressure settings. Three to ten times as strong as modified acrylic esters is its impact strength.

3) Processability: PETG can be processed through a variety of conventional techniques, including extrusion, injection molding, blow molding, and thermoforming. It is also easily shaped.

4) High mechanical strength: PETG can withstand the demands of a range of application scenarios thanks to its high mechanical strength.

5) Outstanding flexibility and minimal water absorption: PETG's exceptional flexibility makes it simple to create products with intricate shapes, including folding and bending. Furthermore, PETG absorbs less water, which helps to preserve the performance and dimensional stability of products.

6) Environmental safety: PETG is easier to recycle and offers greater environmental benefits than PVC. PETG is appropriate for use in the construction industry because it doesn't release any hazardous materials when in use and doesn't deform or produce toxic gases when heated.

7) Good electrical insulation qualities and resistance to chemical corrosion: PETG is a good choice for a variety of applications, including chemical packaging. PETG can be used to make electronic components because of its superior electrical insulation qualities.

8) Biocompatibility: PETG is biocompatible and can be used to make medical devices and other products.

In summary, PETG has excellent impact resistance, a wide processing range, high mechanical strength, good flexibility, environmental friendliness, chemical corrosion resistance, low water absorption, excellent electrical insulation properties, and biocompatibility. Furthermore, PETG has low manufacturing costs and is simple to process and shape, making it cost effective and environmentally friendly in the construction industry. Furthermore, PETG has numerous applications in packaging, medical devices, electronics, automotive components, and optical components.

2.     PETG materials are used in a variety of applications.

The application range of PETG is relatively wide and gradually expanding:

1)Packaging material: PETG has a high degree of transparency and glossiness, making it an excellent choice for high-quality products. It is widely used in food, beverage, cosmetic, and pharmaceutical packaging, among other things.


2) Medical devices: Because of its biocompatibility and heat resistance, PETG is an excellent material for medical devices. It can be used to make syringes, infusion bags, blood bags, and other medical devices.

3) Electronics and appliances: Because PETG has good insulation and heat resistance, it can be used to make electronic components, insulation materials, heat sinks, and so on.

4) Automotive parts: Due to its abrasion and heat resistance, PETG is widely used in the automotive industry, such as bumpers, dashboards, and interiors.

5) Building materials: Because PETG is UV and weather resistant, it is ideal for producing architectural decoration materials such as doors and windows.

6PETG can be used to make high-performance textile fibers such as polyester fibers, spandex, and so on.

7PETG has excellent optical properties and can be used to make optical components such as eyeglass lenses, lenses, and so on.

8) Printed circuit boards and 3D printing: PETG materials are suitable for the 3D printing industry and can be used to improve the heat resistance, abrasion resistance, and UV resistance of printed circuit boards (PCBs).

9) Film materials: PETG has excellent chemical resistance and low water absorption, making it suitable for producing breathable films, waterproof films, heat-sealing films, and so on.

10) PETG can be used to make packaging for personal care products such as cosmetic bottles, shampoo bottles, and so on.

PETG's application in various fields is still expanding as science and technology continue to advance. Simultaneously, in order to meet the needs of various applications, PETG production technology and product performance are constantly optimized and improved.

4. The development of PETG materials has great prospects

PETG has great development prospects, which can be analyzed from the following aspects:

1) Market demand: As the global emphasis on environmental protection and sustainable development grows, so does market demand for PETG as an environmentally friendly and recyclable plastic material. PETG has a wide range of applications, including packaging, food, beverages, cosmetics, medical devices, and so on. Visa, one of the world's largest credit card companies, has issued over 580 million credit cards made of PETG material.

2) Expansion of application fields: As technology advances, the application fields of PETG will expand further. PETG has enormous market potential in the fields of new energy vehicles, 5G communication, high-end electronics, and so on.

3) Policy support: The government attaches great importance to environmental protection and sustainable development and provides policy support for environmentally friendly new materials like PETG. With the continuous release of policy dividends, the development of the PETG industry will receive more policy support.

4) Technological development: With the continuous advancement of technology, the production process and product quality of PETG will be further improved. Research and development of new PETG products will bring new opportunities for industry development.

5) Industry competition: The PETG industry is highly competitive, which will drive enterprises to increase R&D investment, improve product quality, reduce costs, and enhance market competitiveness. After the baptism of market competition, the industry will present a healthier and more orderly development trend.

Wankai New Materials Co., Ltd. established a wholly-owned subsidiary, ZheJiang KaiPuQi New Materials Technology Co., Ltd., in 2022. The company is committed to building a new material technology enterprise with polyester innovative applications as its core. In order to meet market demands, the company has developed high-transparency PETG sheets (CPT-3906) specifically designed for injection molding. It has excellent processing performance, good flowability, high transparency, good stress whitening resistance, and can be shaped according to designers' intentions.


Overall, the PETG industry has broad prospects for development. With the growth of market demand, expansion of application areas, policy support, and technological progress, the PETG industry will enter a stage of rapid development. At the same time, industry competition will also promote the improvement of PETG product quality and the expansion of the market.
