PETG

PETG – Amorphous polyester

PETG

PETG is a clear, amorphous thermoplastic. Its best qualities include good impact strength and resistance to low temperatures. It is well suited to thermoforming and machining, which makes it a popular material in vacuum‑forming. PETG is available as bio-compatible version, making it suitable for use in the food and drinks industry. We deliver PETG as plastic sheets.
