Compact copolyester and glycol sheet
PET-G UV sheets are compact, thermoplastic polyester sheets characterised by high impact resistance, good reaction to
combustion, and good resistance to weathering.
The high performances of the material are confirmed by a 10-year guarantee on mechanical and optical properties.
PET-G UV sheets are quickly thermoformed, with low energy consumption and in extreme deep drawing conditions, and the forms are easy to reproduce and do not require pre-drying.
PET-G UV sheets are available in transparent version offering outstanding transparency and great brightness, or in Opal 30 white version with
good light diffusion and a pleasant hue.
BENEFITS OFFERED BY SHEETS
- Good resistance to weathering
- Very good thermoformability
- Good impact resistance
- Good rating thanks to their fire reaction properties
APPLICATIONS
PET-G UV is the ideal material for all protective glass types installed outdoors, displays, point of sale displays, advertising boards, vending machines, poster framing, and backlit images.

AVAILABLE SIZES
Transparent PET-G UV sheets are available in thickness from 2 mm to 6 mm and in standard size, i.e. 2050x3050 mm.
Other sizes are supplied upon request and/or based on minimum order volumes.
WORKING TEMPERATURE
The maximum working temperature without load is approx. +65 °C.
THERMOPLASTICITY
Thanks to outstanding properties such as fluidity and moulded-in detail reproducibility, PET-G UV sheets can be thermoformed at low temperatures without the need for pre-drying.
Thanks to their poor specific thermal capacity, PET-G UV sheets can be thermoformed with low energy consumption, including when complex 3D forms have to be manufactured.
SUITABLE FOR FOODSTUFFS
PET-G UV sheets are not suitable for applications in contact with foodstuffs.
