Acrylic sheeting is well-known for its wide selection of colors, glossy appearance, durability, and high resistance to various forms of wear and tear. However, acrylic sheets are also available in an extensive range of types and grades, each offering different properties.
Acrylic sheets can be broadly classified, offering a wide array of options based on their manufacturing process, physical properties, and intended applications. This classification helps users select the most suitable type of acrylic sheet for their specific needs, ensuring optimal performance and longevity.
1. By Manufacturing Process
Acrylic sheets are primarily produced through two methods: cast acrylic and extruded acrylic.
Cast Acrylic Sheet
Manufactured by pouring liquid acrylic monomer into molds where it solidifies, cast acrylic sheets are known for their superior optical clarity, excellent weather resistance, high impact resistance, and superior strength.
They are ideal for applications requiring various shapes and customized designs due to their ease of fabrication and ability to maintain structural integrity over time.
Extruded Acrylic Sheets
Produced by continuously pushing acrylic resin through a die, extruded acrylic sheets offer consistent thickness and are generally more affordable.
While they maintain good optical clarity and UV resistance, they tend to be less impact resistant and may turn yellow faster when exposed to prolonged direct sunlight compared to cast acrylic.
2. By Optical and Surface Properties
Acrylic sheets also vary by their surface finish and light transmission characteristics, including clear sheeting as a key category, as well as:
Clear Acrylic Sheet
Clear acrylic sheet, also commonly referred to as clear acrylic sheeting, is known for high optical clarity and light transmission. These clear acrylic sheets are incredibly versatile materials suitable for a wide range of applications, including glazing, display cases, and lighting fixtures.
Compared to other materials such as glass and polycarbonate, clear acrylic sheets offer superior impact resistance, lightweight properties, and enhanced durability, making them a preferred choice for many uses.
Colored Acrylic Sheets
These sheets are infused with vibrant pigments, and acrylic maintains its clarity and translucency even when colored, providing decorative accents without compromising structural integrity.
Textured Acrylic Sheets
Featuring embossed or debossed surfaces, textured surfaces are a defining feature of textured acrylic sheets, offering privacy and unique aesthetic appeal by diffusing light and reducing glare.
Mirrored Acrylic Sheeting
Acrylic mirrors, also known as mirror acrylic, are a durable alternative to traditional mirrors. Combining the reflective properties of glass mirrors with the lightweight and shatter-resistant benefits of acrylic, these sheets are perfect for interior decoration and safety applications.
Light Diffusing Acrylic Sheets
Designed to evenly distribute light, with light diffusion as their primary function, these sheets prevent hot spots and luminance fluctuations, enhancing the visual impact of illuminated signs and displays.
The frosted surface diffuses light, reducing glare and reflection, making it ideal for applications such as privacy screens, partitions, decorative panels, and lighting fixtures.
3. By Functional Coatings and Treatments
Certain acrylic sheets are enhanced with specialized coatings, such as abrasion resistant coating, to improve performance in specific environments:
Abrasion Resistant Acrylic Sheets
