Can you shatter plexiglass?
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.
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).
Cut or Score to Break Edge
Fit a circular saw or table saw with a fine blade with crosscut teeth to prevent chipping the piece during the cut. Line the plexiglass sheet along the cut line. Use the saw at a slower speed, or keep the material cool by spraying water over the cut point during the saw operation.
Though the benefits of plexiglass are that it is stronger, more shatter-resistant, and resistant to the elements and erosion than glass.
If they were all the same thickness, a small rock could break a sheet of glass, a hammer could break acrylic, and — unless it was swung by Thor — the hammer would bounce off a sheet of polycarbonate. In Coastal Florida, hurricanes with winds up to 150 mph are a part of life.
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.
The biggest difference between Plexiglas® and some traditional acrylic is the way they are manufactured. Acrylic can be manufactured one of two ways: extruded or cell cast. Plexiglas®, however, is manufactured in cell cast only. That is the biggest benefit to purchasing Plexiglas® over other brands of acrylic sheeting.
Plexiglass has approximately 17 times the impact strength of glass, making it ideal for windows, retail displays, and other applications.
Most homeowners settle for ⅛ or ¼ thickness, which is quite clear and allows plenty of light inside your room. However, if you want the glass to be a little thicker, you can opt for 3/16, which is more resistant.
Thicker plexiglass, strangely enough, allows for the simplest of the cutting processes. First, grab a metal ruler and a utility knife (preferably one with a brand new blade). Measure the ruler against the cutting line and then draw the knife repeatedly down its edge, gradually increasing the pressure with each pass.
How do you manually cut plexiglass?
How to Easily Cut Plexiglass and Acrylic Sheets - YouTube
Despite its lower price point, it is 10 times more impact resistant than glass. In the unlikely event that acrylic plastic does break, it will fracture into dull-edged pieces instead of sharp, dangerous shards. These properties contribute to acrylic's popularity as windows for commercial buildings.
The coated acrylic sheet, Plexiglas® SBAR, offers 40 times the abrasion resistance of uncoated bullet resistant acrylic sheets. Bulletproof acrylic sheet is commonly used in applications such as banks, convenience stores, ATMS, taxicabs, prisons, and more.
| UNITS | ACRYLIC | |
|---|---|---|
| Tensile strength (73°F) | psi | 10,000 |
| Tensile modulus of elasticity (73°F) | psi | 400,000 |
| Tensile elongation (73°F) | % | 4.5 |
| Flexural strength (73°F) | psi | 17,000 |
Plexiglass is stronger than glass
Regular plexiglass is much more impact resistant than annealed glass and also stronger than tempered (heat-strengthened) glass.
To cut plexiglass, a circular or table saw that has carbide-tipped teeth is the best tool.
Its ultimate tensile strength of 9500 psi and yield tensile strength of 9000 psi means that it would be able to withstand the pressure of being approximately 20,000 feet underwater before suffering permanent deformation or breakage.
When installing plexiglass, it will be necessary to cut it to size to fit a certain opening. There are a variety of ways to cut plexiglass, and one of the least expensive methods is to use a hacksaw, especially if you only have a few pieces of plexiglass to cut.

Harmless when burned
Every disadvantage has its corresponding advantage, and with Plexiglass the advantage is that when burned it burns away completely to water vapour and carbon dioxide, completely harmless substances. When burned, it will also hardly form any smoke, the flue gases are completely harmless.
At what temperature does plexiglass soften?
When Perspex sheet is heated to 140° - 170° it becomes flexible and can be formed into complex shapes by the application of force such as air pressure or mechanical press clamping. If held to that shape and cooled below 90°C it will retain the shape and if re-heated will return to its original flat condition.
Polycarbonate is the stronger material at 250 times the impact resistance of standard glass. Polycarbonate offers much more resilience than acrylic, making it ideal for highly demanding applications like bullet-resistant windows.
Plexiglass and Lexan are brand names for the plastics commonly known as acrylic and polycarbonate. Acrylic is less expensive and easier to fabricate, but can shatter if impacted with enough force.
We can give a short answer to this: there is absolutely no difference. This is because acrylic is the usual abbreviation for polymethyl methacrylate, and Plexiglas® is one of the many brand names of this plastic.
- Keep the plastic film on. As mentioned above, plexiglass usually comes with a thin layer of plastic film intended to prevent scratches as the material travels from manufacturer to retailer to your workshop. ...
- Score deep. ...
- Use the right blade. ...
- Keep the blade cool.
Both have benefits and drawbacks. Generally speaking, acrylic sheeting is shinier and polycarbonate sheet is stronger.
Plexiglass is 10 times stronger than glass and half the weight. It also has exceptional weathering characteristics, and can withstand exposure to sunlight and cold weather. Nominal 1/4" Thick (actual thickness will be approximately . 189" to .
Acrylic plastic is a lightweight, shatter resistant, transparent plastic that is often used as an alternative to glass.

Is plexiglass bullet proof?
Bullet resistant plexiglass is the most commonly bought bulletproof material as it can be drilled, cut, routed, and mounted seamlessly to any structure without cracking or shattering.
