Optical Performance & Diffusion
More Information
Applications
By integrating micro-prism structures with opal or translucent diffusion levels, they reduce glare, improve visual comfort, and maintain high light efficiency. Widely used in:
- Office & Commercial Lighting: Ideal for LED panels, ceiling troffers and downlights.
- Architectural Design: Used in pendant lights, wall panels, and decorative luminaires to create modern, stylish interiors with soft diffusion.
- Public Spaces: Perfect for airports, stations, and schools, where durable, glare-controlled lighting is essential for safety and comfort.
- Healthcare & Laboratories: Provides bright yet gentle illumination, reducing eye strain in sensitive environments.
- Industrial Applications: Delivers wide-area, efficient lighting for factories and warehouses.
Available Widths and Lengths
The standard sheet width is 1220 mm, while for special requirements we can extend the extrusion width up to 1250 mm on request.
We offer standard sheet lengths of 1220 mm, 1830 mm, 2440 mm, and 3050 mm. If your project requires a different size, we can also produce custom lengths tailored to your specifications.

Materials: Comparison of PMMA, PC, and PS
This table helps you understand key differences at a glance, so you can pick the best material.
| Property / Feature | PMMA (Acrylic) | PC (Polycarbonate) | PS (Polystyrene) |
|---|---|---|---|
| Light Transmission | Very high | High | High |
| Impact Resistance | Low – brittle, can crack under stress | Very high – shatter-resistant | Low – brittle |
| Heat Resistance (Continuous Use) | 80–90°C | 120°C | 70°C |
| Maximum Short-Term Heat | ~100°C | ~135°C | ~80°C |
| UV Resistance / Weathering | Good (can yellow over long-term) | Moderate UV stability (However we add UV stabilizer) | Fair (Prone to yellowing)However we add UV stabilizer. |
| Flammability / Safety | Moderate (UL94 HB) | Better (UL94 V-2/V-0 with additives) | Moderate (UL94 HB) |
| Chemical Resistance | Good (resistant to mild acids/alkalis) | Excellent – resists most chemicals | Poor – sensitive to solvents |
| Weight / Density | 1.18 g/cm³ | 1.2 g/cm³ | 1.05 g/cm³ |
| Processing / Fabrication | Thermoforming, laser cutting, CNC. | Good for thermoforming, no laser cutting, CNC. | CNC. |
| Cost | Medium | High | Low |
| Durability / Lifespan | Moderate – good indoor use | Very high – suitable for harsh/industrial environments | Fair – medium-term indoor use |
| Common Applications | Office LED panels | Industrial/warehouse lighting, outdoor luminaires, impact-prone areas | Cost sensitive projects |
Product Tolerances
The three materials — PMMA, PC, and PS — exhibit comparable tolerance levels.
| Property | Value |
| Thickness | ±3% |
| Mother board Length / Width | ±3.0 mm |
| Cut-to-Size Length / Width | ±0.3 mm |
| Light Transmittance & Haze | ±2% |
PMMA has the highest thermal expansion among the three materials. It tends to expand when it’s hot and shrink when it’s cold. To ensure a perfect fit, use our Thermal Expansion Calculator to estimate the final dimensions before installation.
Packing
At Hexatron Technologies, we ensure our diffuser sheets are carefully packed so they arrive in perfect condition.
1. Standard Sheet Packing
- Mother Sheets: Large sheets (up to standard extrusion sizes) are stacked on pallets or crates.
- Final Cut / Cut-to-Size Sheets: Smaller sheets are carefully wrapped and separated with protective films or kraft paper, then bundled to avoid bending or warping.
2. Protection Methods
- Surface Protection Film: All diffuser sheets are supplied with a removable protective film to prevent scratches and contamination.
- Edge Guards / Corner Protectors: To prevent chipping or denting during handling and shipping.
3. Palletization & Securing
- Sheets are stacked on pallets or crates with interleaving layers and secured with straps or stretch film to prevent movement during transit.
- Maximum stack height is calculated based on sheet thickness and material to avoid warping or deformation. A pallet of 1.5 tons is the maximum weight.
4. Shipping & Handling Recommendations
Handling: Use gloves when removing protective film to prevent fingerprints.
Flat Storage: Sheets should be stored flat and supported evenly to maintain flatness.
Climate Considerations: Avoid prolonged exposure to extreme temperatures or humidity, especially for PMMA, to prevent dimensional changes.
