Material Acrylic - PMMA (plexiglas)
PMMA (polymethyl-methacrylate) is an amorphous thermoplastic material with very good optical properties (as transparent as glass and it allows 92% of the sunlight to pass!).

PMMA is hard, stiff and medium strong, easy to scratch, notch sensitive, but easy to polish.

Exceptional outdoor performance, such as weather and sunlight resistance, without reduction neither of optical nor mechanical properties.

Environmen- tal notes Creation: Production of 1 kg of PMMA requires the equivalent of about 2 kg of oil (raw material and energy).

Use: -

Disposal: Incineration in an incineration plant mainly produces water and carbon dioxide. Heating value is equivalent to 1/2 kg of oil.
Additional Info PMMA tolerates weak acids and bases, but neither strong ones nor solvents or acetone.
