The ACRYLITE® Advantage: Quality and Consistency

We've got some eye-opening insights for you regarding the cast acrylic sheet market and the quality of materials you use. You may not be aware, but some importers are cutting corners at the expense of your projects, products, and production. POLYVANTIS Sanford LLC is here to shine a light on these practices and offer a better way.


The Risks of Working with Imported Cast Sheet

Some imported cast acrylic sheets are susceptible to a practice known as "down-gauging". It's a cost-cutting measure where thinner sheets are produced, compromising quality and integrity. By offering an exceptionally wide tolerance range, the manufacturer is able to engage in this undesirable practice without consequence.

The results of these cost-cutting measures can have a negative impact on the effectiveness of the acrylic and, in turn, on your product and/or application. Often, down-gauging leads to uneven lighting, reduced structural strength, and even ineffective bonds.

Understanding Thickness Variations in Imported Cast Sheet

Thickness variations can be as high as 1.2 times the desired size.

For example, an imported sheet with a specified thickness of 0.118 inches (3mm) may exhibit thickness ranging from 0.098 inches to 0.138 inches (2.49mm to 3.51mm)*, resulting in ~20 percent difference.

The ACRYLITE® Advantage

At POLYVANTIS Sanford LLC, we uphold the highest standards with our commitment to strict manufacturing standards, including "True Gauge" thickness. ACRYLITE® products maintain consistent thickness tolerances and quality, ensuring your designs and products are the best they can be. No compromises allowed.


With true-gauge material, you can count on:

1. Uniform Light Transmission:
For applications where acrylic is used to diffuse or transmit light, such as light fixtures, signage, or skylights, consistent thickness ensures uniform light transmission. Any variations can cause uneven illumination, shadows, or hotspots, negatively affecting the intended lighting effect.

2. Optical Clarity and Visual Appeal: Uniform thickness ensures consistent optical clarity and visual appeal. Irregularities in thickness can cause distortions, waves, or variations in transparency. In applications like picture frames, museum displays, or architectural elements, any inconsistencies in thickness can detract from the aesthetics and overall quality of the display.

3. Structural Integrity:
Uniform can be critical role in applications where acrylic serves as a structural element, such as windows, signage, or protective barriers. It is of utmost importance in maintaining the material's strength and durability. Irregularities in thickness can lead to weak points and stress concentrations, thereby undermining the material's capacity to withstand external forces or impacts. Furthermore, the correct thickness is frequently mandated to ensure compliance with safety and impact resistance standards.

4. Seamless Joints and Assemblies: In applications that involve joining multiple pieces of acrylic like display cases or intricate artistic installations, uniform thickness is crucial for creating seamless, watertight, or airtight connections. Differences in thickness can result in visible gaps or leaks, jeopardizing the functionality and aesthetics of the final product.

5. Custom Sizes for Better Yields: ACRYLITE® acrylic provides the flexibility to produce custom sizes, improving material yield efficiency. This eliminates limitations based on the manufacturer's glass size, allowing you to optimize your material usage and reduce waste.

ACRYLITE® Premium (FF) is the highest quality extruded acrylic on the market today providing tight thickness tolerances, preventing visible distortions and inconsistencies in fabricated parts.
