Fluted Boards (eg. Corflute™)
Almost comes under the heading of papers and boards. An extruded plastic sheet similar in construction to fluted card. Has a flat outer surface on both sides, separated by flutes of plastic running the length of the sheet. Thicknesses generally range from 1.5mm to 10mm. Widely used for low cost outdoor signage, and for high strength in folded indoor displays.

H.I.P.S. (High Impact Polystyrene)
In its thinner varieties (0.25 - 0.50 mm) used widely in the printing of images for back-lighting. Thicker sheets (1.0 to 5.0 mm) used for vacuum-forming, laser cutting and fabrication in the construction of permanent and semi-permanent indoor product displays due the economical pricing. Not generally used outdoors due to low UV resistance which can result in the material yellowing and becoming brittle over time.

A.B.S. (Acrylonitrile Butadiene Styrene)
Similar in appearance to HIPS, but more opaque and far less liable to cracking and splitting. Excellent UV resistance. Commonly used for vacuum-forming, laser cutting and fabrication in the construction of permanent point-of-sale displays. Thicknesses generally range from 1.0 to 6.0 mm.

Acrylic (eg. Perspex™, Lexan™)
Available in clear and any number of other colours, although clear, opal(translucent) and black are the most commonly used. Various different types available having different properties, such as high impact resistance right through to poly-carbonate acrylic which is used in security and other applications requiring very high resistance to impact. Acrylic sheeting is primarily used in the fabrication of permanent, indoor point-of-sale displays. Thicknesses generally range from 1.5 to 8.0 mm.

P.V.C. (Poly Vinyl Chloride)
Used as a material for extruded sections for its high rigidity even in small material thicknesses - although with rigidity comes brittleness. Clear material in sheet form is used as a low cost material in temporary point-of-sale units - although the material can have a slightly "milky" tinge (where high clarity is required P.E.T.G. is usually substituted).

P.E.T.G. (Polyethylene Terepthalate, Glycol Modified - eg. VIVAK™)
A clear material with excellent UV resistance (available), high impact resistance and excellent clarity. A premium material for use in permanent indoor and outdoor point-of-sale units.

Polypropylene
An extruded sheet material with excellent flexibility and impact resistance, at the expense of rigidity. Not available in clear. Can be printed, has high chemical resistance and recyclable. Used in both indoor and outdoor displays, as well as die cut presentation wallets and dump bins. Thicknesses generally range from 0.4 to 2.0 mm.
