PS is the brand name for Polycasa's extruded Crystal Polystyrene sheets, offering solutions for many indoor applications.

As well as clear, anti-reflex and standard opal white, a variety of colours and designs are also available as a result of the extrusion process Polycasa can offer.

CHARACTERISTICS

Good optical properties and a brilliant surface.

High light transmission (min 88% wavelength: 500 nm, thickness 3 mm).

Low price.

Low density (1.05).

Good chemical resistance and high rigidity.

UV-stabilised - remains colour constant for many years when used indoors. (On special request Polycasa PS sheets can be produced without UV-stabilisation. They then meet all current food contact legislation and can be used in contact with foodstuffs.)

Possibility of corona treatment - process to increase surface tension. (The result after corona treatment is a surface that is unchanged to the naked eye, but in fact is much more receptive to inks, coatings, and adhesives.)

Polycasa PS sheets also combine the following excellent properties:

Excellent transparency.

Good surface hardness.

Good recyclability.

Low water absorption.

APPLICATIONS

Picture frames.

Shower cabin doors (flat and curved).

Indoor glazing.
