PS (polystyrene) is a thermoplastic material with extremely good hot forming properties and a favourable price. The electrical properties are also very good. PS is initially transparent and at that point demonstrates poor impact strength. Impact-resistant sheets are always densely coloured. Its processing properties are good, and the material is able to be bonded, welded and hot formed.
PS is available as semi-finished products such as clear/patterned sheets, densely coloured sheets and films.
