PETG - Polyethylene Terephtalate Glycol

PETG is a thermoplastic polyester that provides excellent toughness, chemical resistance and is easy to thermoform

PETG, also known as glycolised polyester. The "G" represents glycol modifiers, which are incorporated to minimize brittleness

PETG is resistant to common cleaning chemicals and the effects of weather

PETG fabricates well using processes like die cutting, drilling, routing, bending and polishing. It bonds easily using solvents or adhesives.

PETG is even FDA compliant, so it can be used in medical and food applications. In medical applications, it stands up to radiation and chemical sterilization techniques without changing color

Can be screen-printed, painted, and hot-stamped   

Common heat gun removes surface scratches and scuff marks

Won't turn white with cleaning solutions   

Resists chipping and cracking, safe to saw and drill  

Can be punched, die-cut, laser-cut, welded, riveted, and bonded  

Routes and edge-polishes smoothly  

Clean the sheet with a solution of lukewarm water and a little neutral soap and rinse with fresh water, using a very softsponge or chamois

PETg has  greater impact resistance than acrylic. And minor surface scratches can be removed with a heat gun
