PETG sheet – cut to size

PET-G sheets transparent, food-safe

PETG sheets are used in many areas, including advertising, mechanical engineering and medical technology. They are ideal for applications such as signs, displays, protective covers and medical device housings. This versatility makes the PETG sheet a popular choice in many industrial and commercial areas.

PETG sheets are robust plastic sheets with high impact resistance and transparency. They combine flexibility, ease of machining and resistance, which makes them ideal for numerous industrial applications.

Thanks to their outstanding properties, they are very popular in various areas of industry and the trades. PETG (polyethylene terephthalate glycol*) is often regarded as the perfect choice when it comes to ease of machining and excellent mechanical properties.

*Polyethylene terephthalate glycol: A thermoplastic material with high transparency and impact resistance. PETG combines flexibility, stability and durability in one material, making it a reliable solution for a wide range of requirements.

Although PETG sheets are often used for the production of signs and displays, they are also a cost-effective alternative to materials such as acrylic glass. Compared with acrylic glass, PETG sheets offer higher impact strength and better flexibility, while being less prone to breakage.

They are also easier to machine and more resistant to chemicals, which makes PETG more versatile in many areas of application. They not only offer high resistance to mechanical loads, but can also be processed very well using various techniques. These plastic sheets are known for their resistance to UV rays and chemicals, which makes them particularly attractive for use in demanding environments. They are also lighter than many other transparent plastics, which is a significant advantage in areas where weight matters.

Processing and advantages of PETG sheets

Easy machining and versatility

Machining PETG sheets is particularly easy. The material can be sawed, milled, drilled and even thermoformed. Due to its thermoformability, PETG is ideal for applications where adaptation to special shapes is required. Unlike acrylic glass, PETG can also be cold-cut, which means less heat exposure is necessary. This property is particularly advantageous because it minimises deformation of the material and improves the final quality of the machined sheets.

Another advantage lies in the possibility of easy bonding. PETG sheets can be processed well both with special adhesives and by welding, which facilitates assembly and further processing. This enables flexible design, making PETG suitable for a wide range of construction projects and technical applications. The option of laser processing also ensures precise and clean edges, which is important in areas such as shopfitting and advertising technology.

Chemical and weather resistance

Thanks to their outstanding chemical resistance, PETG sheets are ideal for use in environments where contact with acids and alkalis plays a role, such as chemical laboratories, industrial production facilities or food processing. Outdoors, they impress with their UV stability, meaning they show no yellowing or material change even after a longer period. This resistance to weather influences is crucial for outdoor applications, such as protective covers and transparent façade elements.

PETG also remains dimensionally stable under fluctuating temperatures and changes neither its colour nor its structural properties. The material is resistant to mechanical wear, which makes it ideal for heavily stressed applications that require a long service life. Due to this combination of resistance, flexibility and transparency, PETG is the perfect material for many technical solutions.

Properties

PETG sheets are characterised by their high impact resistance. Unlike acrylic glass, which can be relatively brittle, PETG sheets offer a flexible yet stable structure that can withstand greater loads without breaking. This makes them particularly suitable for applications where high safety and robustness matter. They also offer an exceptionally good balance between strength and formability, which means they are both durable and versatile.

PETG sheets are transparent, which makes them an ideal choice for applications where a clear view or a visually appealing surface is required. They also have good resistance to various chemicals and a low moisture absorption rate, which makes them ideal especially for technical applications. Due to these properties, PETG is often used in areas where precision and high optical clarity are crucial.

Applications

Use in industry

PETG sheets are widely used in industry, particularly in mechanical engineering, where robust and easy-to-machine plastic parts are required. The material is also valued in the automotive industry due to its high impact resistance and formability. The high resistance to mechanical loads makes PETG the preferred choice for machine parts, protective cladding and covers.

Another area of application for PETG sheets is the packaging industry, particularly when it comes to durable and safe packaging solutions, such as food packaging or blister packaging. Here, PETG is used because of its food suitability, which ensures that no harmful chemicals transfer into packaged products. PETG combines robustness with the ability to be formed into precise shapes, which makes it ideal for customised packaging.

Advertising and display construction

Thanks to their optical clarity and brilliance, PETG sheets are outstandingly suitable for use in advertising, for example for signs, displays and point-of-sale stands. The high transparency ensures an appealing presentation of the content and makes PETG sheets the ideal choice for shopfitting. Illuminated displays and protective covers for advertising boards are also often made from PETG, as the material is not only visually attractive but also extremely robust and durable.

Another advantage in the field of advertising technology is the option of printing. PETG sheets can be printed directly, which opens up a wide range of design possibilities. The combination of resistance and printability makes them the preferred choice for both indoor and outdoor applications. These properties ensure that PETG signs retain their quality and colour brilliance for a long time even under challenging weather conditions.

Applications in medical technology

PETG sheets are also widespread in medical technology, as they meet the strict requirements regarding hygiene and resistance. They are used, for example, for protective devices for medical equipment, covers for medical work areas and transparent barriers. Due to their chemical neutrality and the possibility of easy cleaning, they are used among other things for protective cladding and covers. Medical device housings and transparent protective devices are also frequently made from PETG to ensure safe and durable use.

PETG sheets are also used in laboratories, as they are both resistant to most chemicals and easy to sterilise. The combination of resistance, easy processing and hygienic advantages makes PETG an ideal material for a wide range of medical applications where reliability and safety matter.

For applications with lower mechanical requirements, PETG is an economical choice. The material can be formed well, is crystal clear and easy to machine. However, if there are increased requirements for impact resistance or temperature resistance, for example for roofing, protective glazing or technical covers, it is worth looking at an alternative: Polycarbonate sheets for higher demands on strength.

Are PETG sheets weather-resistant?

Yes, thanks to their UV stability and weather resistance, PETG sheets are very well suited for outdoor use. They retain their transparency even under prolonged sunlight and do not discolour. The high resistance to external influences ensures that PETG remains stable and clear even under challenging climatic conditions. Further information on: Weather-resistant sheets for outdoors

How can PETG sheets be machined?

PETG sheets can be machined in a variety of ways. They can be sawed, drilled, milled and even formed by thermoforming. Bonding or welding PETG is also possible without problems. In addition, the material is outstandingly suitable for laser processing, which allows precise contours and smooth surfaces to be achieved, which is an advantage in the manufacture of high-quality products.

What are PETG sheets particularly suitable for?

Due to their high impact strength and easy processing, PETG sheets are particularly suitable for applications in mechanical engineering, advertising and medical technology. They are ideal when robust, formable and at the same time transparent plastic materials are required. Other typical fields of application are shopfitting, protective devices in the automotive industry and medical covers.
