Advantages of Polycarbonate (PC) Sheets for Lighting Boxes, Advertisements & Signage
1. Ultra-high Light Transmittance & Uniform Light Diffusion
Clear PC solid sheets achieve light transmittance up to 90%, comparable to glass. Diffused frosted PC panels evenly scatter LED light sources without dazzling bright spots, eliminating uneven lighting inside light boxes. They deliver soft, uniform backlit display effects for billboards, store signs and channel letters.
2. Super High Impact Resistance & Anti-breakage Safety
PC sheets are 200 times more impact-resistant than glass. They withstand external collisions, hail, accidental knocks and vandalism without cracking or splintering into sharp fragments. Outdoor roadside signs, high-rise advertising light boxes and street signage avoid broken glass hazards, greatly lowering maintenance risks.
3. UV Coating Prevents Yellowing, Long Service Life
Premium PC sheets adopt integrated co-extruded UV protective layers to block ultraviolet rays. Long-term outdoor exposure will not cause yellowing, fogging or discoloration, keeping the color and brightness of advertising patterns stable. Resistant to acid rain, dust and coastal salt mist, with stable performance all year round.
4. Lightweight Material Reduces Installation & Frame Costs
PC weighs only half the weight of glass of the same thickness. It eases handling and transportation for large-format light boxes and oversized advertising signs. Lighter loads simplify aluminum or metal support frames, cutting material costs and lowering the risk of wall or hanging structure overload.
5. Easy Processing & Rich Customization
PC sheets support laser cutting, saw cutting, thermoforming and cold bending. They can be made into curved, arched, three-dimensional shaped signage and special-shaped light box covers. Printing, screen printing and UV inkjet printing can be directly applied on the surface, satisfying diverse personalized advertising design demands.
6. Low Rain Noise & Weather Adaptability
PC panels absorb the impact sound of raindrops much better than glass. For outdoor hanging light boxes, tapping noise during rainy days is greatly reduced. The material withstands extreme temperatures from -40°C to 120°C, free from cracking in cold winters or softening under high-temperature sunlight.
7. Flame Retardant & Safe for Commercial Use
PC reaches Class B1 flame retardant grade. It self-extinguishes after leaving fire sources and produces no molten burning drips. Ideal for shopping mall indoor light boxes, storefront signage and crowded public area advertisements, complying with building fire safety regulations.
8. Good Chemical & Corrosion Resistance
PC resists weak acids, alkaline dust and daily atmospheric contaminants. It will not be corroded by vehicle exhaust, industrial dust or coastal salt spray, requiring minimal regular cleaning and maintenance for long-term outdoor advertising facilities.
