PETG

Polyethylene terephthalate glycol also known as PETG is a thermoplastic polyester providing the characteristics of significant chemical resistance, excellent formability, and durability. The material can be easily vacuumed and bent due to its low forming temperatures.
PETG has a great thermoforming characteristic for applications that needs complex die-cuts and detailed molds without dismantling its original structures. The product is mostly used in fabricating face mask and burn management devices.
The polyester is cost-effective and strong when compared to acrylic or polycarbonate. Its unique characteristics makes it suitable material for high-strength display units. Alongside, PETG can be used as food plastic and are fully recyclable. It is both vacuum-formable and thermoformable and hence can tolerate tremendous amount of pressure.

General PETG Properties

Impact resistance – It is lower-cost alternative to polycarbonate and is less brittle than acrylic.

Thermoforming – It has a thickness up to 0.080 and does not require drying prior to forming. Hence it has a rapid thermoforming cycle.

Chemical resistance – It has superior chemical resistance compared to other transparent plastics.

PETG sheet – For interface evaluation, it is mostly used.
