What is a Transparent Acrylic (PMMA) Diffuser?
A transparent acrylic (PMMA – Polymethyl Methacrylate) diffuser—also known as acrylic, Plexiglas, or Orgala—is one of the best and most widely used polymer materials for manufacturing lighting diffusers with the highest level of optical clarity. This product is produced using advanced extrusion technology and premium-grade PMMA engineering polymer, serving as a cover and light distributor in high-quality LED lights, architectural lighting, display showcases, and luxury lighting systems.
The transparent acrylic diffuser, with light transmission exceeding 92% and clarity close to glass, is one of the best options for applications where maximum brightness and visual quality are paramount. In addition to providing uniform light distribution, this product eliminates glare and hot spots, delivering a superior visual experience for users.
Advantages of Using Transparent Acrylic (PMMA) Diffusers
1. Highest Clarity and Light Transmission
The acrylic diffuser offers light transmission of 92–94%, making it one of the clearest polymers available on the market. This feature makes it an ideal choice for lights requiring maximum brightness and minimum light loss. Compared to glass, PMMA is much lighter while offering comparable clarity.
2. Excellent UV Resistance and Yellowing Prevention
One of the most important advantages of acrylic diffusers is their high resistance to UV radiation. Unlike some other polymers that turn yellow and lose clarity when exposed to sunlight, PMMA—with specialized stabilizers—maintains its clarity and visual quality for years. This characteristic is critical for outdoor applications, architectural lighting, and high-exposure environments.
3. Superior Appearance with Smooth, Glossy Surface
Acrylic diffusers produced via extrusion feature a smooth, glossy, defect-free surface. This aesthetic quality makes them ideal for applications where product visibility matters, such as retail showcases, luxury lighting, and decorative luminaires.
4. Good Chemical Resistance
Acrylic offers good resistance to many chemicals, including dilute acids, bases, and non-polar solvents. This property makes it suitable for industrial and laboratory environments where contact with chemicals is possible.
5. Light Weight and Easy Installation
The specific gravity of PMMA is approximately 1.19 g/cm³, roughly half that of glass. This light weight makes handling, installation, and transportation of acrylic diffusers much easier, significantly reducing shipping and installation costs.
6. Customizability in Various Sizes and Thicknesses
Transparent acrylic diffusers can be manufactured in custom lengths up to 6 meters, thicknesses from 0.5 to 5 mm, and with smooth, matte, patterned, or corrugated surfaces. This flexibility allows lighting manufacturers to order diffusers precisely tailored to their product designs.
Differences Between Acrylic (PMMA) and Polycarbonate (PC) Diffusers
A common question in the lighting industry concerns the differences between these two materials. Below is a comprehensive comparison:

| Clarity | Very high, near glass | High, but slightly bluish |
| Impact Resistance | Moderate | Very high (~10× PMMA) |
| Heat Resistance | Up to 80°C | Up to 130°C |
| UV Resistance | Excellent (with stabilizers) | Good (with stabilizers) |
| Chemical Resistance | Good | Good |
| Price | Economical | Higher than PMMA |
| Primary Applications | Luxury lighting, showcases, architecture | Industrial environments, impact-prone areas |
| Specific Gravity | ~1.19 g/cm³ | ~1.20 g/cm³ |

Factors Affecting the Price of Transparent Acrylic Diffusers
The price of transparent acrylic diffusers is influenced by several factors:
1. Quality and Brand of Raw Materials – Using top-grade European or Asian raw materials with high purity affects the final price. Faradid Polymer uses the finest PMMA grades available.
2. Thickness and Dimensions – Greater thickness and longer lengths mean more material and higher production costs, thus a higher price.
3. Surface Type (smooth, matte, patterned) – Producing patterned or matte surfaces requires more specialized molds and complex processing, which can increase cost.
4. Order Quantity – High-volume orders typically benefit from lower overhead costs and thus more economical pricing.
5. Special Additives – If specific additives like enhanced UV stabilizers, anti-scratch coatings, or custom colors are required, the final price will increase.
