1/4" x 18" x 24" - Clear Acrylic Plexiglass Sheet - Cast - (Paper Mask) features:

  • Laser cuttable and can be engraved
  • Remarkable clarity
  • Shatter resistance relative to traditional glass
  • Light weight and easy to handle

Plexiglass Acrylic (PMMA - Polymethyl Methacrylate) is a versatile plastic material that has great impact strength yet is light weight with exceptional optical quality. Our clear plexiglass sheets can be used for a number of applications such as signage, glazing, displays, picture framing, aquarium tanks, and much more. It also has exceptional weathering characteristics, and can withstand exposure to sunlight and cold weather. Plexiglass can be sawed, drilled, routed, painted, decorated, silkscreened, formed, and laser cut. Plexiglass is 10 times stronger than glass and half the weight.


Nominal 1/4" Thick (actual thickness will be approximately .189" to .250").

Allow + or - 1/8" tolerance in width and length.

Paper masking on both sides.

Cell cast plexiglass acrylic.

All four edges are saw cut.

Cell Cast Acrylic Plexiglass - Key Characteristics & Properties:

  • Made by pouring liquid acrylic monomer into a glass mold.

  • Cell cast sheets can be laser cut and laser engraved. Extruded sheets can also be laser cut, but its not recommended for laser engraving.

  • Slightly better optical clarity than extruded.

  • Wider range of thickness available compared to extruded.

  • Cell cast sheets have a higher resistance to impact than extruded sheets by virtue of the manufacturing process. Basically, when acrylic is extruded, the force of the rollers squeezing the material to make it thinner introduces stress during the extrusion process. With cell cast, there is no stress introduced during the manufacturing process, producing a stronger molecular structure of the sheet.

  • Cell cast sheets have a higher thickness tolerance compared to extruded sheets. The thickness can vary throughout a cell cast sheet. For example, in a nominal 1/8" (.118" or 3mm) cell cast sheet, some sections of the sheet may be .100" thick while other sections of the sheet may be .120".

  • Machines better than extruded sheets (cutting, drilling, routing). Less melting during machining than extruded sheets.

  • Cell cast sheets are relatively more scratch resistant than extruded sheets.

  • Generally better at chemical resistance than extruded sheets.

Is plexiglass and acrylic the same thing?

Plexiglass, plexi-glass, lucite, acrylite or acrylic glass are often used interchangeable with acrylic (similar to the way Kleenex® and tissue paper are used interchangeable). When spelled Plexiglas® (spelled with one s), it refers to the Röhm brand name. When spelled as plexiglass (spelled with two s's) it is in reference to generic acrylic sheets. There are several manufacturers of acrylic sheets. The actual brand we ship out will depend on current stock. Plexiglas® is a registered trade name of Röhm GmbH and is not a brand we typically stock.


What is the difference between paper masking and film masking?

All of our plexiglass acrylic sheets come with a protective masking on both sides. Our clear cell cast pre-cut pieces will come with a paper masking. We also have clear extruded pre-cut pieces in both film masking and paper masking. The plastic film masking is typically blue in color or clear.

Paper masking is thicker than film masking and thus offers more protection when handling, especially when machining. However, film masking is easier to peel off than paper masking.


What is the difference between plexiglass/acrylic and polycarbonate (aka lexan)?

Plexiglass/acrylic and polycarbonate are both polymers and two of the most popular plastic materials. Both have clear visibility and are stronger than typical glass. However, one of the main differences between the two is that polycarbonate is significantly more impact resistant than plexiglass/acrylic and resist cracking and chipping much better. To give you an idea of the difference in strength between the two, if you were to throw a plexiglass sheet down on a concrete driveway, it would most likely crack and break. A polycarbonate sheet would just bounce off the driveway.

Plexiglass/acrylic is easier to machine and form. Polycarbonate is much more expensive than plexiglass. Polycarbonate offers more corrosion resistance when used in chemical applications, but it is less scratch-resistant than plexiglass. Plexiglass/acrylic has less degradation over time than polycarbonate.

Polycarbonate (aka lexan) is a material that should not be used for laser cutting projects. Polycarbonate sheets will release toxic and dangerous fumes when laser cut that will cause serious health damage. These fumes can also damage your laser machine.

Examples of polycarbonate applications: protective windows, protective visors, machine guards, and other high risk applications.


Acrylic Plexiglass Care Instructions

DUSTING: We like to use micro-fiber cloths, but you can also use a soft damp cotton cloth or chamois to remove dust..

CLEANING: Use a small quantity of soap and lukewarm water, rinse well with clean water, and dry with a micro-fiber cloth, chamois, or soft cotton cloth. Never use ammonia-based glass cleaners, solvents or alcohol. We recommend a product called BRILLIANIZE.

FOR SCRATCH REMOVAL: After years of use and cleaning, plexiglass may develop fine surface scratches. We recommend using NOVUS 2 with a 100% cotton clothe to buff out fine scratches.

CAUTION – DO NOT USE: Window cleaning fluids, scouring compounds, gritty cloths, household scouring compounds, lacquer thinner, benzene, leaded or ethyl gasoline, strong solvents containing alcohol, acetone, or carbon tetrachloride, or ammonia.


We also offer custom cut-to-size, hole drilling, edge polishing, CNC cutting, circle, and shape cutting. Request a quote for these services.
