PETG Properties

Physical, mechanical, thermal, electrical, and optical properties of PETG

PETG is a transparent plastic material with outstanding thermoforming characteristics for applications that require deep draws, complex die cuts and precise molded in details, without sacrificing structural integrity. Due to its low forming temperature, PETG is readily vacuum and pressure-formed, heat bent, and it bonds easily using solvents or adhesives. It displays good clarity, chemical resistance, impact resistance, and is FDA compliant. PETG is widely used for signs, POP displays and store fixtures, machine guards and housings, and thermoformed trays.

PETG is a good choice for O&P fabricators where transparency is important, and is commonly used when fabricating face masks, burn management devices, and check sockets. Please ask your Curbell Plastics representative for more specific information.
