Cast Acrylic Sheets

30mm-480mm thickness | Ship to Worldwide | UV Resistant

Cast acrylic sheets, also referred to as optically glass-like plexiglass, are manufactured from a continuous cast process with extremely high optical clarity thermoplastic material.

Acrylic is used in a wide variety of applications because it can be easily thermoformed and machined, making it an extremely versatile material suitable for a wide range of applications. Excelite® Acrylic is a thermoplastic substrate, can it be further processed through thermoforming into numerous shapes and designs. When heating to the applicable softening temperature, Excelite Acrylic will exhibit a level of shrinkage in length and width of a max.3%.

Compared to all other types of transparent thermoplastics, acrylic has outstanding resistance to the damaging effects of sunlight and outdoor weathering.

Most commercial acrylics have been UV stabilized for good weather ability and resistance to sunlight exposure.

Optical Clarity: Cast acrylic offers extremely high light transmission and clarity, greater than 92% light transmission. This makes it ideal for applications like aquariums, displays, and lighting fixtures.
UV Resistance : UV additives make cell cast acrylic highly resistant to ultraviolet light and solar radiation compared to other thermoplastics. It stands up very well in outdoor applications.
High Strength: Cell cast acrylic has higher tensile and flexural strength than standard extruded acrylic. It has over 12 times the impact strength of glass.
Thermal Stability: The cell cast manufacturing process results in low internal stresses and high dimensional stability over temperature changes. It can withstand 120-170°F continuously.
Ease of Fabrication: Cell cast acrylics can be readily machined, thermoformed, and fabricated to create custom enclosures, displays and more.

Acrylic Sheet Care

Acrylic is a relatively soft material and can scratch easily if not taken care of. It also naturally builds up a static charge and can attract dust easily. We suggest the two most recognized Acrylic cleaners available: Novus and Brillianize.

The differences of Cast Acrylic Sheets Vs. Extruded Acrylic Sheets

Differences in Processing Performance

Continuous Service Temperature: 180° F (Cast Acrylic Sheet) vs. 160° F (Extruded Acrylic Sheet)
Formability Temperature Range: 340° F to 380° F (Cast Acrylic Sheet) vs 290° F to 320° F (Extruded Acrylic Sheet)
Cast acrylic has a higher molecular weight, therefore it will cut, drill and rout cleaner.
Ease of Machining: When machining cast acrylic, shavings will flake off whereas extruded acrylic shavings may gum up on the tool.
Glue-joint effectiveness: It offers stronger glue joints with cast acrylic sheets and performs better in laser cutting.
Higher optical clarity: Cast acrylic typically has light transmission of 90-93% and above and extruded acrylic sheet ranges 85-90% light transmission. This can make a noticeable clarity difference.
Better UV resistance: Additives cast acrylic sheet provides increased protection from yellowing degradation.

Differences In Properties

Properties/ Features	Cast Acrylic	Extruded Acrylic
UV Stability	Excellent	Good: UV resistance, but might not perform as well as cast acrylic sheet while direct sunlight.
Clarity	Superior optical clarity with high light transmittance	Good, suitable for most applications
Wight	Slightly heavier due to its density	Slight lighter than cast acrylic
Chemical Resistance	Resistant to many chemicals but can be affected by strong solvents.	Generally resistant to common chemicals, but specific resistances may vary.
Scratch Resistance	High: More resistant to scratches	Less resistant to scratches, but much better than polycarbonate sheets
Colours	Available in a wide range of colours and thicknesses.	Fewer colours available, primarily under MOQ requirement.
Thickness Tolerance	Varied: +/- 15% thickness variability.	Consistent: +/- 10% thickness variability.
Flame Polishing	Produces cleaner edges, but more time-consuming.	Easier to achieve, but might not result in as clean of an edge.
Cost	Generally more expensive due to its properties and manufacturing process.	More cost-effective, making it a popular choice for projects with budget constraints.
