CAST is the brand name for cast polymethylmethacrylate sheets from Polycasa® .

The composition of the final product is 90-95% PMMA + additives (stabilisers, plasticisers, dyes and pigments, and release agents).

CHARACTERISTICS

Optical transparency of 93% light transmission for transparent sheets — significantly lighter and far more impact-resistant than glass of the equivalent thickness.

Resistant to UV rays, good thermal stability and low water absorption.

Easy to handle — most fabricating and moulding techniques are applicable to it, allowing attractive designs.

APPLICATIONS

Signs.

Displays.

Furniture.

Sanitary fittings.

Gift articles.

Shopfittings.

Solariums.

Boat windows.

Projection screens.

Skylights.

Barrel vaults.

Partitions.

Doors.
