A comprehensive guide to light blocking films — also known as black PET films, blackout films, optical density films, and light shielding materials. Explore applications, specifications, and how to choose the right opaque film for your LED, display, or electronics project.
Both Polycarbonate and Polystyrene prismatic diffusers can achieve TP(a) rigid fire classification under UK Building Regulations Approved Document B. See our SGS-certified test results and learn what TP(a) means when specifying UGR<19 lighting for commercial, educational, and public spaces.
Learn how IK ratings measure LED diffuser durability — and how Polystyrene, PMMA, and Polycarbonate compare across impact resistance, transmittance, and UV stability. A practical guide to specifying vandal-resistant, UGR<19 compliant lighting for any environment.
In lighting design, materials need to do more than just look good — they must perform, adapt, and last. At Hexatron, we’ve worked with optical-grade materials for years, and when it comes to thermoformed diffusers, one material stands out: PMMA (Polymethyl Methacrylate). Why PMMA Is Ideal for Thermoforming PMMA, also known as acrylic, offers several advantages that make it […]
In critical environments like hospitals, laboratories, and cleanrooms, lighting plays an essential role not only in visibility and aesthetics but also in hygiene, safety, and human well-being. In such places, every component of the lighting system—from the housing to the diffuser—must meet strict standards for durability, optical quality, and chemical resistance. One of the most […]
How optical diffuser films and prismatic sheets combine to achieve UGR<19 in LED panels. Covers prism profiles (Honeycomb, Hexagon, Pyramid), diffuser film grades, assembly methods, and optical stack design for commercial lighting.
LED diffusers are at the heart of every luminaire — from office ceiling panels and retail displays to street lights and medical equipment. But not all diffusers are equal when it comes to chemical safety. The materials used — polycarbonate (PC), PMMA, and polystyrene (PS) — often contain additives for UV protection, flame resistance, and […]
When designing LED lighting, engineers must balance optical performance, thermal stability, and fire safety. One critical indicator for safe material selection is the Glow-Wire Flammability Index (GWFI), a global standard used to evaluate a plastic’s resistance to ignition. At Hexatron, our optical-grade materials are tested and certified to meet IEC 60695-2-12 standards, ensuring both optical […]
Thermal Expansion Calculator: Easily Predict Heat & Linear Expansion of PMMA Sheets Materials like PMMA (acrylic) don’t stay the same size when temperatures change. They expand when heated and contract when cooled, which is why understanding thermal linear expansion is essential in lighting, display, and architectural applications. To make this process simple, we created an easy thermal expansion calculator that […]
A complete guide to black LED diffusers — how they work, material options (PS, PMMA, PC), transmittance levels, UGR compliance, and applications in architectural, retail, pendant, and industrial lighting design.
