Acrylic
Acrylic is cell-cast sheet made to exacting standards, offering excellent optical characteristics, light stability and low internal stress levels for consistent performance. Sheets are available in a wide range of standard sizes, thicknesses and colours.
Like Polycarbonate, Acrylic is available in a wide range of grades including optical, UV resistant and scratch resistant grades. It is generally a little cheaper than Polycarbonate but even in modified grades does not possess the same impact and scratch resistance.
