1. Material Quality:

The quality of the acrylic resin used to manufacture the sheets significantly affects their price. High-quality acrylic sheets are made from premium-grade resins that offer enhanced clarity, durability, and weather resistance. Lower-quality acrylic sheets may contain impurities or inferior additives, resulting in reduced performance and a lower price point.

2. Thickness:

The thickness of acrylic sheets is another key determinant of price. Thicker sheets require more raw material and undergo additional processing, resulting in higher production costs. While thicker sheets offer increased durability and impact resistance, they also come at a higher price compared to thinner options.

3. Transparency and Clarity:

Acrylic sheets are prized for their optical clarity, but achieving a high level of transparency often requires additional processing steps and quality control measures. Sheets with superior transparency and clarity command a higher price due to the added manufacturing complexity and improved visual appeal.

4. Surface Finish:

Acrylic sheets are available in various surface finishes, including glossy, matte, textured, and mirrored. Sheets with specialized finishes or coatings may cost more than standard clear acrylic due to the additional processing involved and the aesthetic value they offer.

5. Color and Pigmentation:

Colored acrylic sheets or those with added pigments typically cost more than standard clear acrylic. The cost of pigments and dyes, as well as the complexity of the manufacturing process to ensure color consistency and uniformity, contribute to the higher price of colored acrylic sheets.

6. Size and Customization:

The size of acrylic sheets and any customization or fabrication requirements can also impact their price. Larger sheets and custom-cut sizes may incur additional handling and transportation costs. Similarly, specialized fabrication techniques such as laser cutting or engraving can increase the overall price of acrylic sheets.

7. Brand Reputation and Warranty:

Acrylic sheets from reputable brands with a proven track record of quality and reliability may come at a premium price. However, investing in a trusted brand often ensures superior product performance and customer support. Additionally, acrylic sheets with comprehensive warranties may cost more upfront but offer long-term peace of mind and cost savings.

8. Market Demand and Supply:

Fluctuations in market demand and supply can influence the price of acrylic sheets. During periods of high demand or limited supply, prices may increase due to supply chain constraints or production costs. Conversely, lower demand or increased supply may result in price reductions or promotions.

In conclusion, when evaluating the price of acrylic sheets, it's essential to consider factors such as material quality, thickness, transparency, surface finish, color, size, brand reputation, and market dynamics. While opting for lower-priced acrylic sheets may seem cost-effective initially, investing in higher-quality options often pays off in terms of durability, performance, and long-term value. By understanding the balance between quality and cost, you can make informed decisions and select acrylic sheets that meet your project requirements and budget constraints.

What's The Difference Between Cast and Extruded Acrylic Sheets?

Cast vs extruded acrylic sheets. What is better for your upcoming project? Here is a guide to help you decide which is the best one for your project.

Cast Acrylic is created when the acrylic liquid is pumped in between a mold of two pieces of glass and submerged in warm water.

This manufacturing method allows for smaller batches than the extruded material. Therefore, most of the colored or textured acrylic that you see is probably cast acrylic. When comparing cast and extruded acrylic, cast acrylic is usually deemed the higher quality of the two even though they both have benefits over the other. Here are some benefits of cast over extruded acrylic sheets:

  • More scratch resistant
  • Higher chemical resistance
  • Cleaner edge after being cut or CNC machined (less time polishing)
  • Can be produced in many different colors and thicknesses

Extruded Acrylic is created when the acrylic liquid is pushed through a form. The direction in which it is extruded can later affect fabrication.

  • More cost effective
  • Easier to flame polish
  • Lower thickness tolerance

In general, cast acrylic is recommended for fabrication projects. The uniformity of the sheet creates a better end result with CNC machining, polishing, and gluing. If you are using the material with limited fabrication involved, like windows, extruded acrylic is a great option. It is more cost effective than cast acrylic and still has better clarity than glass. Here is a side by side comparison:

Which is better cast or extruded acrylic?

Determining whether cast or extruded acrylic is better depends on the specific requirements and preferences of your project. Here are some key points to consider:

Cast Acrylic:

  • Higher optical clarity and transparency
  • Greater dimensional stability and resistance to warping
  • Better impact resistance, less prone to shattering
  • Superior surface finish and polish
  • Offers a wider range of thickness options
  • Typically more expensive than extruded acrylic

Extruded Acrylic:

  • Lower cost compared to cast acrylic
  • Good dimensional stability, less susceptible to expansion and contraction
  • Excellent weatherability, suitable for outdoor applications
  • Available in a variety of colors and finishes
  • Can be easier to fabricate and process
  • Generally has lower optical clarity compared to cast acrylic

Ultimately, the choice between cast and extruded acrylic depends on your specific needs, budget, and desired properties for your project.

Paper vs Plastic Film

Paper vs plastic film? Every sheet of acrylic comes with a protective film or paper covering it, and depending on your project, one option can be preferable over the other. Our fabrication department and customers prefer paper backing with CNC machining or fabricating acrylic. The paper gives you the option to peel it back a few inches or remove the paper from different sections that you are working on while leaving the rest of the material protected against damage. If you are CNC machining, paper is a necessity as film can become caught on the CNC machine and cause damage.

Here is a prime example of our fabrication department removing or peeling back the paper from areas they are flame polishing. The rest of the material stays covered and protected from damage.

Anyone that has ever had to peel the paper off several sheets of acrylic can attest to how much time it can take. Removing film is much easier and less time-consuming. This makes it a better option for people handling a large number of acrylic sheets that will be installed with minimal fabrication.
