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
