These material specs should be used as a guide. PETG is found in a variety of sign and display applications including fabricated 3D point of sale display units, medical appliances, flat sheet installations and vacuum forming.
There are several solutions for cutting PETG:
PETG has inbuilt temperature resistance of between -30°C to 65 °C. APET has -20 °C up to 65
°C..
Up to 84% of visible light is transmitted through clear PETG.
PETG has a class 1 fire rating under the UK BS 476 Part 7 regulation, “difficult to ignite” This the same flammability resistance as both polycarbonate and aluminium composite.
In order for PETG to bend, it must be heated to a temperature of between 100°C – 110°C. The material can
then manipulated to shape. Usually PETG is heated on both sides when bending to shape however single
sided bending is possible.
The polymers in the material makeup of PETG allow for it to be v-grooved for fabrication. However PETG
can only folded a certain number of times, before potential fracturing occurs after v-grooving.
Like other stocked substrates, PETG interact best with drill bits especially designed for plastics. Although
metal or woodtwist drills can be used, they require careful application and slower drilling speeds in order to
produce clean results..
Lorem ipsum dolor sit amet, conPETG adheres best with ‘Evo-StikExtru-Fix’ but also works with a range of other bostik glues including,
‘Evo-Stik Mirror Adhesive’, ‘Bostik 7452’, ‘Simson ISR 70-03 & Prep M’and THF (Tetrahydrofuran). Butt, lap
and face joints are all achievable using these adhesives.
PETG can in fact be vacuum formed.
Both silk screen and tampo (gravure) printing techniques are applicable. UV curing inks have also good
keying properties with PETG
