Sunroom Polycarbonate Sheet with 2mm Thickness and 5-Year Warranty

What is a **polycarbonate sheet**? Chemically, polycarbonate sheets are a new type of material made primarily from polycarbonate resin. Because polycarbonate sheets are often hollow, they are also referred to as hollow sheets. They were first used in the building decoration industry in the 1980s. Later, as domestic architectural aesthetics and other requirements improved, more and more construction projects began to use polycarbonate sheets, leading to wider recognition and understanding among customers. Polycarbonate sheets can be categorized into various types, including double-layer polycarbonate sheets, four-layer polycarbonate sheets, diamond-patterned polycarbonate sheets, locking polycarbonate sheets, honeycomb polycarbonate sheets, and more. These sheets are used in different fields, such as greenhouse roofs, unique decorations in amusement venues, city curtain walls, windshields, transparent containers, and several other areas. 1. **Light Transmission**: The light transmittance of polycarbonate sheets can reach 89%, comparable to that of glass. UV-coated sheets will not yellow, fog, or lose transparency under prolonged sunlight exposure; after ten years, the light loss is only 6%, whereas PVC has a loss rate of 15%-20%, and fiberglass is 12%-20%. 2. **Impact Resistance**: The impact strength is 250-300 times that of ordinary glass, 30 times that of acrylic sheets of the same thickness, and 2-20 times that of tempered glass. Even when dropped from two meters using a hammer weighing 3kg, there are no cracks, earning it the nickname "shatterproof glass" and "sound steel." 3. **UV Protection**: One side of the polycarbonate sheet is coated with UV-resistant (UV) coating, while the other side has anti-condensation treatment, combining UV protection, heat insulation, and drip prevention functionalities. It can block ultraviolet rays from passing through, making it suitable for protecting valuable artworks and exhibits from UV damage. 4. **Lightweight**: Its specific gravity is only half that of glass, thereby saving costs on transportation, handling, installation, and support frames. 5. **Flame Retardant**: According to national standard GB50222-95, polycarbonate sheets are classified as difficult to ignite, level B1. The burning point of polycarbonate sheets is 580℃, and they self-extinguish after the flame is removed. They do not produce toxic gases during combustion and do not promote the spread of fire. 6. **Flexibility**: They can be cold bent on-site according to design plans to create arch-shaped, semi-circular roofs and windows. The minimum bending radius is 175 times the thickness of the sheet, and they can also be hot bent. 7. **Sound Insulation**: The sound insulation effect of polycarbonate sheets is significant, providing better sound insulation than glass and acrylic sheets of the same thickness. Under the same thickness conditions, the sound insulation of polycarbonate sheets is improved by 3-4 dB compared to glass. They are used internationally as materials for sound barriers on highways. 8. **Energy Efficiency**: They keep cool in summer and warm in winter. Polycarbonate sheets have a thermal conductivity (K value) lower than that of ordinary glass and other plastics, with insulation effectiveness higher by 7%-25% compared to equivalent glass, achieving insulation efficiency of up to 49%. This greatly reduces heat loss, making them an environmentally friendly material for buildings with heating equipment. 9. **Temperature Adaptability**: Polycarbonate sheets do not become brittle at -100℃ and do not soften at 135℃. Their mechanical properties remain stable even in harsh environments. 10. **Weather Resistance**: Polycarbonate sheets can maintain the stability of physical indicators within the range of -40℃ to 120℃. After 4000 hours of artificial climate aging tests, the yellowing degree is 2, and the reduction in light transmittance is only 0.6%. 11. **Anti-Condensation**: When the outdoor temperature is 0℃ and the indoor temperature is 23℃, with indoor relative humidity below 80%, there is no condensation on the inner surface of the material. **Application Areas of Polycarbonate Sheets**: 1. Skylights in office buildings, department stores, hotels, villas, schools, sports venues, entertainment centers, and public facilities. 2. Sound barriers on highways, subways, and urban elevated roads. 3. Roofs for agricultural greenhouses, flower greenhouses, and indoor swimming pools. 4. Canopies at subway entrances, stations, parking lots, shopping malls, pavilions, lounges, corridors, etc. 5. Anti-theft counters in banks, anti-theft display windows in jewelry stores. 6. Advertising lightboxes, bus station panels, advertising displays. 7. Indoor partitions for offices and homes, pedestrian passages, guardrails, balconies, shower rooms, etc. The polycarbonate sheets produced by our company are of high quality and low price.
