In recent years, with the continuous advancement of science and technology and the increasing awareness of environmental protection, various new materials have emerged one after another. Among these new materials, PETG sheets are gradually favored by the market due to their unique advantages and wide range of applications.

So, what exactly is PETG sheet? In what fields can PETG sheets show their talents?

What is PETG sheet?

PETG sheet, the full name is Polyethylene Terephthalate Glycol, is a thermoplastic polymer. Its main components are PET (polyethylene terephthalate) and EG (ethylene glycol). Due to the addition of EG during the manufacturing process, PETG sheets have excellent toughness and transparency, as well as good processing properties and chemical resistance.

What are the characteristics of PETG sheets?

PETG sheets have the remarkable characteristics of high transparency (light transmittance above 90%), strong toughness (not easily broken), chemical resistance, good processability (thermoforming, injection molding, cutting, etc.), and environmental protection.

1. High transparency: PETG sheet has extremely high transparency, with a light transmittance of more than 90%, which makes it excellent in applications requiring high transparency.

2. Strong toughness: Compared with ordinary PET, the toughness of PETG sheets has been significantly improved, and it can withstand large impact forces without being easily broken.

3. Chemical resistance: PETG sheets have strong resistance to a variety of chemicals and can be used in some corrosive environments.

4. Good processability: PETG sheets can be processed through various processing methods such as thermoforming, injection molding, cutting, drilling, etc., and are not prone to cracks or damage during processing.

5. Environmental protection: PETG board is an environmentally friendly material that can be recycled and is in line with the current development trend of green and environmental protection.

What are the main uses of PETG sheets?

With the above superior characteristics, PETG sheets are widely used in the packaging industry (transparent packaging boxes, display cabinets), medical industry (casings of medical devices, pharmaceutical packaging bottles), electronic products (protective covers for electronic equipment, display panels), architectural decoration ( It has been widely used in many fields such as indoor partitions, decorative panels) and industrial manufacturing.

1. Packaging industry:

In the packaging industry, PETG sheets are often used to make transparent packaging boxes, display cabinets, food packaging containers, etc. due to their high transparency and good chemical resistance. These products not only beautifully display the contents inside, but also effectively protect them from the outside environment.

2. Medical industry:

PETG sheets are also widely used in the medical industry. For example, PETG sheets can be used to make shells of medical devices, pharmaceutical packaging bottles, test kits, etc. Its excellent chemical resistance and biocompatibility give it significant advantages in medical applications.

3. Electronic products:

In the manufacturing of electronic products, PETG sheets can be used as protective covers for electronic equipment, display panels, etc. Its high transparency and good impact resistance can effectively protect electronic components and extend the service life of equipment.

4. Architectural decoration:

The high transparency and processability of PETG sheets make them useful in the field of architectural decoration. For example, it can be used as indoor partitions, decorative panels, billboards, etc., which not only meets the aesthetic needs, but also has good practical performance.

5. Industrial manufacturing:

In the field of industrial manufacturing, PETG sheets are often used to produce various mechanical parts, tool handles, protective covers, etc. Its excellent durability and workability make it the best choice for many industrial products.

Market prospects of PETG sheets

With the advancement of science and technology and the continuous expansion of application fields, the market demand for PETG sheets is also increasing year by year. According to data from market research institutions, the average annual growth rate of the global PETG market is expected to reach about 7%. This growth trend is mainly due to the following aspects:

1. Promotion of environmental protection policies: Globally, environmental protection policies are becoming increasingly strict, prompting companies and consumers to be more inclined to choose environmentally friendly materials. As a recyclable material, PETG board caters to this development trend.

2. Expansion of application fields: The application of PETG sheets in many industries continues to expand, especially in the fields of packaging, medical, electronics and architectural decoration, and its market potential is huge.

3. Technological progress: With the continuous improvement of manufacturing processes, the performance of PETG sheets has been further improved, and its application prospects have become broader.

PETG sheet production process

The production of PETG sheets mainly includes: raw material preparation (PET and EG), extrusion molding (extruded into thin sheets), cooling and shaping (forming preliminary PETG sheets), cutting processing, and quality inspection.

1. Raw material preparation: The main raw materials of PETG are PET and EG. Through precise proportioning and mixing, the purity and stability of the raw materials are ensured.

2. Extrusion molding: After the mixed raw materials are melted at high temperature, the molten material is extruded into thin sheets using the extrusion molding process.

3. Cooling and shaping: The extruded sheet is quickly cooled through the cooling device to solidify and shape it, forming a preliminary PETG sheet.

4. Cutting and processing: According to customer needs, the cooled and shaped PETG sheets are cut and processed to obtain finished sheets of the required size and shape.

5. Quality inspection: Strict quality inspection is carried out in all aspects of production to ensure that the performance and quality of the final product meet the standards.

Conclusion

To sum up, PETG sheet, as a new type of material, is becoming an indispensable and important material in various industries with its superior characteristics and wide range of applications. With the continuous advancement of science and technology and the continuous growth of market demand, the application prospects of PETG sheets will be broader.

Whether in the fields of packaging, medical care, electronics, architectural decoration or industrial manufacturing, PETG sheets show strong vitality and unlimited possibilities.
