Night Acrylic Sheet

Night Acrylic Sheet is a functional sheet that uniformly disperses long afterglow phosphor in PMMA substrate. After absorbing visible light for 10-30 minutes during the day, it can continuously emit light for 8-12 hours in dark environments, with initial brightness ≥2000 mcd/m² and afterglow decay complying with GB/T 24982 standard. It offers two mainstream luminous colors: yellow-green and blue-green, with thickness ranging from 2mm to 10mm and standard size of 1220×2440mm. The surface can be optionally treated with matte or high-gloss finish, making it an ideal material for emergency indication and decorative lighting.

Core Features

Application Scenarios

Emergency Indication

• Safety Signage: Emergency exit signs, evacuation route indicators, fire passage signs
• Public Facilities: Subway emergency indicators, underground parking lot guidance, tunnel escape signs
• Transportation: Night escape systems for airplanes, ships, high-speed trains

Decorative Lighting

• Interior Design: Wall decoration, furniture inlays, ceiling starry sky effects
• Architectural: Building outline lighting, landscape lights, art installations
• Events: Stage settings, holiday decorations, theme park night scenes

Special Applications

• Military: Night march markers, equipment identification tags
• Industrial: Equipment control panels, instrument dials, night operation guidelines
• Consumer Products: Creative gifts, stationery, home accessories

Technical Parameters

Processing and Installation

• Cutting: Laser cutting (recommended) to avoid high temperature damaging phosphors; mechanical cutting requires fine-tooth saw blades
• Engraving: Can be laser engraved with patterns, engraving depth ≤0.5mm to retain luminous layer
• Thermoforming: Heating temperature 140-160℃, holding time reduced by 30% to minimize phosphor migration
• Bonding: Use acrylic-specific glue, avoid adhesives with excessive solvents
• Installation: Avoid long-term exposure to strong light (may cause temporary saturation), installation gap ≥2mm
