Building a Better Machine Guard With Plastic
Stiffness, impact resistance, clarity, and chemical resistance are keys to selecting the right plastic for a machine guard.

PETG

Transparent plastic sheet with good impact resistance and outstanding thermoforming characteristics

PETG has outstanding thermoforming characteristics for applications that require deep draws, complex die cuts and precise molded in details, without sacrificing structural integrity. It is used often in the O&P market for fabricating face masks, burn management devices, and check sockets. PETG is FDA compliant.

PETG Properties and Material Options

Thermoforming– PETG does not require drying prior to forming and has rapid thermoforming cycle times. It is brake formable up to 0.080" thickness.

Impact Resistance– PETG is less brittle than acrylic, and is a lower cost alternative to polycarbonate.

Chemical Resistance– PETG offers superior chemical resistance when compared with many other transparent plastics.

PETG Sheet for O&P– is used where transparency is important for evaluation interfaces.

Tech Tip– PETG sheet is a lower cost alternative to polycarbonate.
