Why does plexiglass crack?

The majority of times you see cracking and crazing in plastics such as Acrylic, Perspex, Plexiglas (PMMA), Polycarbonate (PC) and Ultem (PEI) is due to lack of the correct heat treatment. These such plastics need careful normalising and annealing steps throughout the machining, bonding and polishing process.

What are the disadvantages of plexiglass?

Perspex sheets melt at high temperatures or from exposure to direct flames. The melting point for acrylic plastic is 160 degrees C, so they cannot withstand extreme temperatures. Acrylic is tough and durable, but can also be easily scratched. The manufacturing process of acrylic products can release highly toxic fumes.
