The certification rules concerning acrylic sheets bear the number 116. They can be downloaded from the website

CSTB (Scientific and Technical Centre for Building) tests the products and audits the companies within the scope of this certification.

  • A Vicat softening point ≥ 105° C
  • Water absorption ≤ 40 mg
  • Thermal stability during its transformation (no surface deterioration)
  • A tensile strength greater than 60 Mpa
  • Stability of colours to light and hot water
  • Resistance to chemicals, hot water and staining


All of these tests check the fitness of sheets to meet sanitary purposes.

When only a few sheets have been used, make sure that the rest are repacked.

  • it is recommended to store sheet horizontally on their original palettes
  • it is strongly recommended not to stack palettes so as not to create internal stresses and alter the sheet flatness
  • an excessive thermoforming temperature may deteriorate the sheet protective film and make it more difficult to remove

Film guarantee

The thermoforming properties of the film are guaranteed during one year from the manufacturing date which is printed on the sheet.

This guarantee is valid if the sheet have been stored according to the recommendations given above.

An excesive thermoforming temperature may deteriorate the sheet protective film making it more difficult to remove.


  • Do not handle the Altuglas® sheet with bare hands, the edges are sharp and this could pollute the surface. If possible, wear clean leather gloves.
  • Do not wear fluffy, brightly-coloured clothes, the sheet could be polluted by cloth fibers or the cloth colouring could pass through the film, causing stains or marks. Wear white or grey cotton overalls.
  • Do not move the sheet causing them to slide, this could damage the PE protective film and lead to the manufacturing of marked thermoformed products. Two people should carry them or a suction-paddled remover should be used.
