Polyethylene terephthalate glycol / PETG
PETG (or copolyesters) are glycol modified PETs; the modification is done by adding a second glycol during polymerization. The resulting molecular structure is irregular and the material is clear and amorphous with a glass transition temperature of 88 C and melting temperature of 290 C. PETGs can be processed over a wider processing range than conventional PETs and offer good combination of properties such as toughness, clarity, and stiffness.
PETG sheets and rods offer a desirable combination of properties such as clarity, toughness, and stiffness. Applications include medical devices (test tubes and bottles), toys, displays and lighting fixtures, face shields, and refrigerator crisper pans.
PETG rods
PETG rods (thermoplastic copolymer polyester) - lightweight transparent plastic, flexible enough, easy to stretch, used for thermoforming and cold forming. Especially PETG sheets have excellent impact strength, including at low temperatures (down to -40 ° C), as well as good resistance to chemicals. PETG sheets are resistant in a wide operating temperature range -40 ° C + 65 ° C. PETG sheets are perfectly amenable to mechanical processing, good for stamping, and can be..

What are the key properties of Polyethylene Terephthalate Glycol (PETG)?
PETG is known for its excellent combination of properties, which include high clarity, good toughness, and sufficient stiffness. It has a glass transition temperature of 88 °C and a melting temperature of 290 °C, which allows it to be processed over a wider range than conventional PET.
How does the processing of PETG compare to other thermoplastics?
PETG can be processed at lower temperatures and has a wider processing range compared to traditional PET, making it more suitable for various applications where temperature sensitivity is a concern. This property allows manufacturers to utilize PETG sheets and PETG rods in diverse fabrication processes.
What applications are best suited for PETG materials?
Due to its remarkable balance of durability and clarity, PETG is widely used in applications such as packaging, displays, and medical devices. Its ability to be easily shaped and formed while maintaining structural integrity makes it a preferred choice for various industrial and consumer products.
