A technical guide to injection molded light guide plates — covering the manufacturing process, mold design, PC vs PMMA material selection, dot pattern integration, and when injection molding is the right production route for your LGP application.
A complete technical comparison of PMMA, polycarbonate (PC), and polystyrene (PS) for LED diffusers and optical sheets. Covers optical transmittance, impact resistance, fire ratings, UV stability, thermal behaviour, and application-by-application guidance to help engineers and buyers specify the right material first time.
Complete guide to specifying custom graphic overlays and industrial front panels. Compare polycarbonate vs acrylic, screen vs digital printing, hardcoat finishing, and environmental ratings for any application.
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 […]
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.
