Acrylic plastic sheets have 17 times the impact strength of glass, meaning, it takes a lot more force to shatter acrylic than glass. Plexiglass sheeting is unique in that while it is extremely difficult to shatter, it can be broken, however, it doesn't break into a thousand tiny, dangerous shards.
How much force does it take to break acrylic?
In most applications, acrylic is shatterproof with "six to 17 times greater impact resistance than normal glass" reports rplastics.com, able to withstand a compressive impact equal to 18,000 lbs per square inch (psi).17 Jul 2017
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 is plexiglass crazing?
Plexiglas is a durable, corrosion resistant material made from a composite of plastics and used in place of glass. While plexiglass will not break under the same force as glass, it is susceptible to other harm such as crazing, which is a scuffed haze on the plexiglass that limits visibility.26 Sept 2017
Does vinegar harm plexiglass?
Never use vinegar to clean your acrylic windows. While vinegar is a strong and powerful cleaning tool that can safely be used on traditional glass or Plexiglas windows, it is too acidic for acrylic surfaces and will quickly damage your windows.
Will rubbing alcohol damage plexiglass?
Avoid using products with alcohol, ammonia, or aromatics. Products like Windex, which contain alcohol, will significantly damage plexiglass. Also avoid solvents such as acetone, dry-cleaning fluid, or any gritty cleanser or polish, as they will damage the surface of the plexiglass.
Does plexiglass melt easily?
A: While acrylic softens at higher temperatures, it does not actually melt until it reaches 320 °F (160 °C). Therefore, normal household use does not risk melting acrylic. As a safety precaution, never place acrylic directly on or next to an open flame or hot surface.
Does WD-40 ruin plexiglass?

Is plexiglass shatter resistant?
Plexiglass can be used to create beautiful and safer bathroom enclosures, making them more slip-resistant and shatterproof. Even when cracked, plexiglass doesn't shatter, so more extensive fall injuries may be avoided.
