Key Notes

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.

Features
  • FDA approved for contact with food and medical equipment
  • Thermoforming properties for hot line bending and vacuum forming
  • Class 1 UK fire rating “difficult to ignite”
  • High impact strength
  • Excellent weathering and outdoor exposure
  • Optically very good
  • Can be sterilised
  • Good resilience to a range of acid, oils and alcohols.
  • Ideally suited for heat bending and vac forming
  • Easy to cut, machine or paint.
Cutting

There are several solutions for cutting PETG:

  • Manual sawing
    A fine bladed saw is needed and the sheet should be fastened down to avoid any vibrations
  • Knife
    The panel should be scored multiple times before attempting to cut fully through
  • Circular & band saw
    Will produce a better finish than that of manual or knife cutting
  • CNC router
    PETG can be v-grooved to create folding lines for fabrication, at 3mm thickness and above
  • Laser
    Lumex G has been tested and certified by ‘Eurolaser’ for CNC laserability. Anything up to 2mm can be cut Guillotining & punching
  • Die cutting
Weathering

PETG has inbuilt temperature resistance of between -30°C to 65 °C. APET has -20 °C up to 65
°C..

Light Transmission

Up to 84% of visible light is transmitted through clear PETG.

Flammability

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.

Hot Bending

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.

V-Grooving

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.

Drilling

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..

Glues

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.

Vacuum Formed

PETG can in fact be vacuum formed.

Printing

Both silk screen and tampo (gravure) printing techniques are applicable. UV curing inks have also good
keying properties with PETG
