PET-G - clear, transparent

0.020 inches

What is it

Thermoplastic polyester PET is absolutely colourless and has very high light transmission. The sheets are not really suitable for long term use outdoors because they will yellow under the influence of UV. The polyester sheets made of PET-G as a rule conform to the standards of the German testing norm DIN 4102 Class B1, i.e. they are flame resistant. Polyester sheets from PET-G are food compatible as per FDA and BGA regulations.

Design notes

Thermoplastic polyester PET is distinguished by its impact resistance (comparable to polycarbonate). The really special attribute of PET is its ability to be bent “cold”. It can be bent in any angle you want without breaking at the bending point or showing any colouration (crazing) – the 0.5 mm thick sheet will tear after being bent a 100 times to 180° in both directions.

The best temperature for heat shaping the PET-G lies between 120 and 160°. You should try to allow for a long cooling off period after the hot shaping so that the material can hold its form without any stress being put on it. PET reacts extremely well to deep drawing as well.

The laser cuts the material with a nice smooth edge; engraving is recommended only with the settings for heavy vector / raster engraving.

Adhesives, joints & fastenings

PET-G can be glued to itself by using ACETONE or DICHLOROMETHANE; UHU HARD creates a thoroughly satisfactory bond but even better are RUDERER L530, contact adhesives like PATTEX TRANSPARENT, cyanoacrylate adhesive (SUPER GLUE) and reaction adhesives like ACRIFIX. Transparent, acrylate-based DOUBLE-SIDED ADHESIVE TAPES and TRANSFER ADHESIVE TAPES also provide a good means for joining work.

Because of its impact resistance, PET can also be nailed or riveted. Fastenings made with screws come out extremely well but note that counter sunk screws should not be used.
