Optical plastics

Optical plastics include clear and coloured amorphous thermoplastics. Optical plastics can be coated to make them more resistant to chemicals or abrasion.

Optical plastics include PC (polycarbonate or plexiglass), PMMA (polymethyl methacrylate or plexiglass), clear PS (polystyrene), PETG (amorphous polyester) and clear PVC (polyvinyl chloride).

Optical plastics can typically withstand temperatures of less than 100°C but there are exceptions, such as PC.

Read more about specific optical plastics below.

Our product range includes optical plastics as sheets, bars, pipes and as special products in some materials.
