Acrylic

Stiff and brittle easily broken.

2

Polyvinyl sheet (PVC)

Stiff, strong [strong: Able to withstand a force without breaking or bending. ], tough [tough: Able to withstand blows or sudden shocks without breaking. ] and resists scratching

3

High-density PVC foam

Stiff, hard, tough and lightweight, with a good resistance to chemicals

4

Polystyrene sheet (or styrene sheet)

Lightweight, hard, stiff, transparent [transparent: Able to be seen through; clear. ] and brittle. Good water resistance

5

Corrugated polypropylene

Lightweight and tough. Stiff, but not very strong. Hard but scratches easily. Resistant to chemicals.

6

Acrylonitrile butadiene styrene (ABS)

Strong, tough, hard, lightweight, and durable [durability: The ability of a material to withstand wear, especially as a result of weathering. ]. A good surface finish and resistant to chemicals.

7

Polystyrene foam (Styrofoam)

Brittle in tension, lightweight, with good heat and sound insulation

8

Cellophane

Tough, hard, stiff, lightweight, transparent, and non-flammable [non-flammable: Not easily ignited or burnt. NB: inflammable has the opposite meaning - ie, easily ignited. ]

9

Polythene

Hard, stiff and able to be sterilised
