Polyethylene Terephthalate (PET), the G stands for “glycol-modified”, is the most widely used plastic in the world. In fact, if you look around you, you will find that the polymer is used in many different applications such as the creation of water bottles, right up to the fibers of your clothing. It is also widely used in thermoforming processes and can be combined with glass fiber to create resins that are used in the engineering world. Most foods and beverages are delivered and packaged using PET as well. In a nutshell, it is used in so many consumer products, that it is too many to list them all.
PETG offers a high level of durability. This makes it the perfect choice for a wide range of uses such as food containers and tools in the medical profession. Due to the way in which Glycol is added, it removes the brittle properties that come with PET. Therefore, it prevents the material from crystallizing and breaking. PETG’s level of durability also comes with high impact resistant properties and this once again makes it the ideal option for many different uses.
There is no odor with PETG and this is one of the characteristics that make it ideal for domestic use. 3D printing with PETG has a low level of shrinkage. It ensures that the original measurements remain the same, making it perfect for large 3D prints. The filament has a low level of deterioration when it comes to absorption. PETG does not absorb water and that ensures it remains strong. The material is extremely resistant to chemical agents, making PETG perfect for use in the medical profession. This also means that it can be sterilized easily.
PETG is known to be an exceptionally strong material and this makes it ideal for those objects that will be subjected to mechanical stress. It is hard, flexible, and resistant, much of which can be credited to the way it adheres to each layer.
Industries that use PETG
PETG is a good all-around material for 3D printing and that means that it stands out from many of the other filaments that are available. Its flexibility, strength, temperature, and impact resistance make it the first choice for many industries. For those objects that could be put under sustained or sudden stress, such as mechanical parts and protective components, PETG is the perfect option.
Food and Beverage
PETG is popular within the food and beverage industry. It enables food manufacturers to meet the relevant standards of hygiene because the material can be sterilized. It also helps to protect food and beverages because it is impact resistant and is strong and flexible.
Retail Industry
PETG is commonly used in retail and is used to manufacture point-of-purchase stands like exhibition kiosks and displays. Once again, this is down to its flexibility and wide range of colors.
Medical Industry
The medical industry relies heavily on PETG and this is because of its wide range of properties. PETG’s durability makes it perfect for tools, medical equipment, and prosthesis. Of course, also because of the need to remain clean, its sterilization properties make it the perfect choice.
