Stiff and brittle easily broken.
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
High-density PVC foam
Stiff, hard, tough and lightweight, with a good resistance to chemicals
Polystyrene sheet (or styrene sheet)
Lightweight, hard, stiff, transparent [transparent: Able to be seen through; clear. ] and brittle. Good water resistance
Lightweight and tough. Stiff, but not very strong. Hard but scratches easily. Resistant to chemicals.
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.
Polystyrene foam (Styrofoam)
Brittle in tension, lightweight, with good heat and sound insulation
Tough, hard, stiff, lightweight, transparent, and non-flammable [non-flammable: Not easily ignited or burnt. NB: inflammable has the opposite meaning - ie, easily ignited. ]
