As industries turn to sustainable and low-energy alternatives, new materials like this photoluminescent acrylic resin have gained traction, providing a reliable substitute for traditional lighting systems that rely on electricity. According to the report of the global specialty acrylic materials industry in 2025, the photoluminescent acrylic resin market is growing at a compound annual growth rate of 6.2%, and now 78% of commercial and public infrastructure projects give priority to self-luminous security materials (source: Global Acrylic Materials Industry Association). This comprehensive guide breaks down everything you need to know about this innovative product—from its core functionality to its real-world applications—optimized to help buyers and designers make informed decisions.
Night acrylic sheet is a kind of high-performance photoluminescence acrylic board, which is designed to provide continuous lighting in a dark environment without an external power supply. Different from the standard acrylic panels, it is characterized by long afterglow phosphor particles uniformly dispersed throughout the original PMMA (polymethyl methacrylate) matrix, rather than a surface coating. This structural integration ensures durability and longevity, eliminating the risk of the luminous layer peeling or fading over time—a common issue with surface-treated luminous materials. The working principle is simple: this sheet can absorb the visible light of sunlight or indoor lighting (400-700nm) within 10-30 minutes, and then emits soft and uniform light for 8-12 hours in complete darkness. Its initial brightness reaches ≥2000 mcd/m², fully complying with the Chinese national standard GB/T 24982, making it a reliable choice for safety and decorative applications alike.
In recent years, new materials have completely changed the construction and lighting industries, with the emphasis on sustainability, durability and functionality. Traditional emergency lighting systems rely on batteries or an external power supply, which can fail in case of power failure, thus causing security risks in key environments such as subway stations, tunnels and high-rise buildings. This gap leads to the adoption of self-luminous materials, and the night acrylic board stands out because of its unique combination of performance and versatility. Different from other photoluminescence materials, it maintains excellent optical clarity during the day, seamlessly blends with architectural designs, and provides reliable lighting at night. According to the Global Acrylic Material Industry Association, the use of this functional acrylic material reduces the emergency lighting maintenance costs of commercial buildings by an average of 40% (source: Global Acrylic Material Industry Association).
Day and night acrylic (the dual-functional counterpart of night acrylic sheet) is defined by its ability to perform two key roles: it acts as a standard transparent acrylic panel during the day, allowing light to pass through and maintaining a clean, modern appearance, while transforming into a self-luminous source at night. This dual function makes it different from traditional luminescent materials, which usually appear dim or faded in the daytime. Unlike surface-coated luminous boards, day-and-night acrylic resin maintains its transparency (60–80% transmittance according to ASTM D1003) and aesthetic appeal during the day, making it suitable for both functional and decorative applications. Its uniform luminous color (yellow-green (520nm) and blue-green (490nm) can be selected) can ensure no bright spots and provide consistent lighting in a dark environment.
1. Excellent luminous performance: the excitation time of the luminous acrylic board is 10-30 minutes, and the continuous luminous time is 8-12 hours (≥ 0.32 mcd/m²), which conforms to DIN 67510 photoluminescence safety material standard. This ensures reliable lighting in case of power failure or low light, which is very important for emergency evacuation.
2. Durable & Long-Lasting: the uniform dispersion of phosphors within the PMMA matrix prevents the luminous layer from peeling off, even after years of use. It boasts a service life of ≥ 10 years, with ≥80% of initial brightness retained over time, outperforming surface-coated alternatives that often degrade within 3–5 years.
3. Superior Physical Strength: With an impact strength of ≥ 12 kJ/m² (ASTM D256) and flexural strength of 75 MPa, night acrylic sheet is resistant to breakage and damage, making it suitable for high-traffic public areas. Its d 85 Shore hardness ensures scratch resistance and long-term durability, even in busy commercial or industrial environments.
4. Excellent weather ability: it keeps stable performance in temperatures range of -20℃ to 60℃, and it still keeps 80% or higher performance after 500 hours of ultraviolet aging test (source: Global Acrylic Materials Industry Association). This makes it suitable for indoor and outdoor applications, from underground parking lots to outdoor landscape lighting.
5. Easy to process: the acrylic sheet for night use can be cut, drilled, thermoformed, and laser-carved without damaging the luminescent layer. Laser cutting is recommended to avoid high temperatures that could affect phosphor performance, while mechanical cutting requires fine-tooth saw blades for clean edges. This flexibility makes it easy to integrate into all kinds of project designs.
6. Safe & Eco-Friendly: It contains no radioactive substances, complies with RoHS and REACH standards, and has no heavy metal pollution. This makes it safe for use in residential, commercial and public places, including schools, hospitals and child care institutions, where safety is the most important.
