Polyethylene Terephthalate Glycol (PETG)
PETG is a clear and durable amorphous thermoplastic material that is excellent for tubing or profiles.
What is Polyethylene Terephthalate Glycol (PETG)?
Polyethylene Terephthalate Glycol is the glycol modifier and when introduced to polyethylene terephthalate, it strengthens and enhances its durability.
PETG is FDA-certified, which means it can be used to construct food storage containers, packaging, and even water bottles. For clear, disposable food and beverage containers, PETG is a natural choice because of its ability to handle impacts and its strong barriers to the compounds commonly present in beverages.
PETG has a light and pliable build, while also being resistant to impact. Due to its high light transparency, PETG is widely used in storefronts. However, its main downside is its lack of UV resistance. For example, leaving PETG sitting out in the sun for long periods can cause it to melt and warp.
PETG has the ability to form various shapes and maintain a rigid structure once it has dried. It is also very easy to sterilize. For this reason, PETG implants and devices are commonly used in the medical field. PETG is more cost-effective than polycarbonate.
PETG is stronger than acrylic and because it is a thermoplastic, it is highly sought after as a recyclable material.
