Ce marking
A translucent material
A key feature of polycarbonate is its transparency. The use of natural lighting, achieved by installing translucent polycarbonate roofing and walls, creates a more comfortable ambience while also ensuring good thermal insulation. Polycarbonate can be suitably tinted to modulate light transmission, optimise shading and thus reduce overheating inside the building. Coloured pigments are used to achieve pleasant colour effects to satisfy the most demanding aesthetic and architectural requirements.
A versatile material
A safe material
Polycarbonate has a particularly high impact strength. Our products are therefore highly resistant to accidental impacts and hail and meet the requirements of safety standards for translucent glazing in public and work environments.
An environmentally friendly material
The various phases of polycarbonate processing involve very low energy consumption and environmental impact. Polycarbonate is an energy-efficient solution and is totally recyclable at the end of its life.
A light material
Its Properties
Chemical Resistence
The polycarbonate has good resistance to most chemicals with which it is likely to come into contact during normal use. Specific tests are recommended for applications where the material is likely to come into contact with aggressive chemicals. It is essential to verify their compatibility prior to use. The table at the side provides a summary of reactions with some of the main products used.
