How strong is 3mm acrylic?
If you're looking for the perfect kitchen or bathroom splashback, you've found it. Our 3mm acrylic sheeting has unique physical properties and delivers great performance. It's as much as ten times more impact resistant than glass, outstandingly weatherproof, and can be formed into a million shapes.
3mm seems to be a good compromise between weight/stability. One thing you should remember is that lexan is “softer” which means it doesn't crack as easily, but it's not as “clear” as acrylic. From what I hear it's easier to work with though. 5mm should be enough.
A jigsaw is one preferred tool for cutting acrylic sheets. It is a small handheld tool that can cut the sheet with the straight blade by function up and down in fast motion. However, if you intend to cut acrylic into a nonlinear fashion, a jigsaw is the right option for you.
If there's a lot of support underneath the acrylic, you can choose a thinner sheet – although we would still advise a minimum thickness of 5mm – whereas if there is minimal support, we would recommend that you choose a minimum of 8mm in thickness to ensure that it stays stable.
The tensile strength of acrylic is around 8000 psi (it takes 8000 pounds per square inch to break acrylic), while the tensile strength of polycarbonate is around 7000 psi.
3mm acrylic sheets are somewhat flexible when working with large sheets, but smaller panes will be more rigid and so are perfectly suitable as a stronger alternative to glass and so is perfect for replacement picture frame glass.
You can make bends of all types in very thin sheet acrylic, provided you work out the heat and time required for bending thin material and do not pass that point. Thin sheets are easily warped quite far away from the bend. For thinner sheets, you need to apply heat evenly to a very narrow line of the material.

Whether using a hand tool or a power saw to cut plexiglass, it's important to use a sharp blade. A dull blade will fight against the material, potentially causing cracks and breaks—not to mention an overly rough cut edge. Keep the blade cool.

Does acrylic sheet break easily?
When you use acrylic sheeting as your window panes, you no longer need to worry about someone getting injured if a pane is to break. 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.
While not as rigid as the equivalent thickness of glass and so allowing it to be bent to shape simply by hand, it is just as clear and 10x stronger.
Acrylic can scratch easily, so avoid contact with sharp or abrasive items. If you want to place a metal or similarly hard-edged object on top of an acrylic table or tray, Von Furstenberg suggests adhering felt pads to the underside of the piece to prevent it from scraping against the delicate surface.
Acrylic isn't very strong and experiences brittle failure, meaning it cracks immediately without much bending.
Carrying capacity versus impact
Suppose a pane of glass 1 metre wide and 3 millimetres thick breaks at a weight of 1 kilo, then a three-millimetre thick acrylic sheet will break at a weight of 30 kilos.
How Acrylic Compares to Glass. Impact Resistance: Acrylic has a higher impact resistance than glass. It is also 10 times more shatter resistant than glass.
Whether fabricated in cast or extruded forms, acrylic is less expensive while remaining 10 times more impact-resistant than glass. Due to its incredible durability, acrylic can be used over a broad temperature range and has superior weather resistance compared to glass and other forms of plastic.
4mm acrylic sheets are rigid and so are perfectly suitable as a stronger alternative to glass, that is unless using sheets larger than 2m², which may bend slightly if unsupported. If you plan to use a large sheet of acrylic unsupported, we recommend you use a thickness of 5mm or greater.
If you want a 0-12 inches high fish tank, the thickness of the sheets should be ¼ inches. For 13-19 inches height, the acrylic glass should be ⅜ inches thick. For a 20-24 inches aquarium, the thickness of plexiglass should be ½ inches.

How thick does plexiglass need to be to not bend?
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.
OPTIX acrylic sheet begins to soften between 210-220°F and starts to melt between 300-315°F.
Use a pocket knife or Stanley knife with a very sharp edge and score firmly down your sheet using a ruler or straight edge. If the plastic is fairly thin (4mm or thinner) then this should be enough to outline where you want to cut. Score the plastic a few times back and forth and then make the cut.

Acrylic is typically glued using solvent-based glues, such as Weld-On 4. Unlike many other gluing processes, acrylic glue softens the surfaces of the acrylic and welds them together, chemically bonding the two pieces into one.

Circular saws can be used on acrylic sheets of all thicknesses. Use jigsaws with metal cutting blades of reduced depth and sharp teeth (5-6 teeth per cm) - use the finest blade you can. Be sure to allow the blade to stop before withdrawing from the cut.
Acrylic is a transparent plastic material with outstanding strength, stiffness, and optical clarity. Acrylic sheet is easy to fabricate, bonds well with adhesives and solvents, and is easy to thermoform. It has superior weathering properties compared to many other transparent plastics.
We've covered the gluing, now how about the screwing? Yep, that's right, fasteners (in the case of acrylic, almost always screws) are the next biggest method of joining acrylic.
While you can glue acrylic mirrors in place, they can also be screwed into the wall.
What is the difference between acrylic and plexiglass?
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.
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 main advantages | The main disadvantages |
|---|---|
| 30x as strong as glass 2x lighter than glass Less expensive Easier to work with Durable More translucent Safer than glass | More liable to scratching than glass Not heat-resistant |
Light and clarity
UV resistant polycarbonate sheet has a typical product outdoor guarantee of up to 10 years whereas clear cast Perspex® acrylic sheet is guaranteed for 30 years outdoors.
All sheets are protected on both surfaces by a protective peal off layer and are approximately 1/8" thick for quality framing.
If you want a 0-12 inches high fish tank, the thickness of the sheets should be ¼ inches. For 13-19 inches height, the acrylic glass should be ⅜ inches thick. For a 20-24 inches aquarium, the thickness of plexiglass should be ½ inches.
Plexiglass comes in a variety of thickness, typically thicknesses are 1/16", 1/8", 3/16", 1/4", 3/8", 1/4", 1/2", 1", 1.25", 1.5", 2", 2.5", 3", and 4".
