The characteristics of PC endurance boards have made them one of the more popular building materials today. Their application scope has expanded to many fields. In practical use, some projects require processes such as forming and bending of endurance boards, which also highlights the many advantages of these boards. Since PC endurance boards are materials with high water absorption, they need to undergo drying treatment before forming. Additionally, their temperature must be strictly controlled due to the tendency of endurance boards to experience stress cracking, so stress must be prevented. Only through such forming can endurance boards achieve optimal performance and play an important role in various applications.

Bending endurance boards commonly involves two methods: hot bending and cold bending. Hot bending does not require high-quality boards, but its efficiency still needs improvement. Cold bending becomes more difficult with thicker boards and demands higher board quality, but it is more efficient. Through the above introduction, you should now have a deeper understanding of endurance boards.

Sunlight Panel Product Characteristics:
(1) Light Transmittance: PC sunlight panels can achieve up to about 89% light transmittance, comparable to glass. UV-coated panels do not easily yellow, fog, or lose transmittance when exposed to sunlight. After ten years, the transmittance loss is about 10%, while PVC loss is 15–20%, and fiberglass is about 12–20%.
(2) Impact Resistance: The impact strength is about 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. They are known as "unbreakable glass" and "ringing steel."
(3) UV Protection: One side of the PC panel is co-extruded with an anti-UV coating, and the other side has anti-condensation treatment, combining UV resistance, heat insulation, and anti-fogging functions. It blocks ultraviolet rays, making it suitable for protecting valuable artworks and exhibits from UV damage.
(4) Lightweight: The density is about half that of glass, reducing costs for transportation, handling, installation, and support structures.
(5) Flame Retardant: According to the GB50222—95 standard, PC sunlight panels are classified as flame-retardant (B1 grade). The self-ignition point of PC panels is about 580°C, and they self-extinguish after removal from fire. They do not produce toxic gases when burning and do not contribute to the spread of flames.
(6) Bendability: They can be cold-bent on-site according to design drawings to form arches, semi-circular roofs, and windows. The bending radius is about 175 times the panel thickness, and they can also be hot-bent.
(7) Sound Insulation: PC sunlight panels provide significant sound insulation, outperforming glass and acrylic sheets of the same thickness in acoustic insulation. Under the same thickness conditions, the sound insulation of PC sunlight panels is 5–9 dB higher than that of glass, making them the preferred material for highway sound barriers.
(8) Energy Efficiency: They keep interiors cool in summer and warm in winter. PC sunlight panels have a lower thermal conductivity (K-value) than ordinary glass and other plastics, with insulation efficiency 7–25% higher than that of glass. The insulation efficiency of PC sunlight panels can reach up to 49%, significantly reducing heat loss, making them ideal for buildings with heating systems.
(9) Temperature Adaptability: PC panels do not become brittle at -40°C and do not deform at 125°C. Their mechanical and physical properties remain largely unchanged even in harsh environments.
(10) Weather Resistance: PC sunlight panels maintain stable physical properties within a temperature range of -40°C to 120°C. After 4,000 hours of artificial weathering tests, the yellowing degree is 2, and the transmittance reduction is about 0.6%.
(11) Anti-Condensation: At an outdoor temperature of 0°C and an indoor temperature of 23°C with indoor relative humidity below 80%, the inner surface of the material does not condense. Condensation flows along the surface of the panel without dripping.
