This GEM reference has been achieved with Roctool technology which has improved surface quality, compared to conventional technology, in several aspects :

Cette référence de GEM a été réalisée avec la technologie Roctool qui a permis d’améliorer la qualité de surface, par rapport à la technologie conventionnelle, sous plusieurs aspects :

The GEM integrates a nano-structuring surface technology that allows the creation of very fine patterns and thus the fight against counterfeiting, either in a discreet and non-reproducible way, or

Styrene acrylonitrile (SAN) is a copolymer of styrene and acrylonitrile.

It is used as a replacement for polystyrene when better chemical resistance is required.

Thermoplastic of the Polyolefin family. High-density polyethylene is a widely used polymer. Food grade, it has excellent shock resistance and is a good electrical insulator.
