Performance Characteristics and Application Introduction of PC Solid Sheet

There are various building panels in our daily life, among which PC Solid Sheet is a common type. At present, PC Solid Sheet has become a substitute for other building panels and is widely used in various construction projects. Compared with ordinary building panels, PC Solid Sheet boasts prominent advantages. Glass, acrylic boards, PC hollow sheets and PC Solid Sheet differ greatly in application scenarios and performance features. The following introduction may serve as a useful reference. Globally, the application of PC Solid Sheet is developing toward high‑function and specialized directions. Given the production capacity and market demand of PC Solid Sheet in China, together with the establishment of multiple domestic production facilities and the rapid growth of the automobile industry, China’s PC industry will enter a new development phase in the coming years. PC Solid Sheet is extensively adopted in numerous fields of life and production, including construction, healthcare, electronics, electric vehicles and sports equipment, exerting profound influences on people’s daily lives. It has become an indispensable material for social development. From the perspective of development trends, PC Solid Sheet will maintain an irreplaceable important position in multiple industries in the future.

1. What is PC Solid Sheet?

PC Solid Sheet is mainly made of polycarbonate. It is vulnerable to strong acid and strong alkali and prone to aging without UV‑resistant coating. Coated with UV protective layer, this high‑performance engineering polycarbonate (PC) resin panel features high light transmittance, light weight, high impact resistance, sound insulation, thermal insulation, fire resistance and anti‑aging performance. As a comprehensive‑performance energy‑saving plastic panel widely used in plastic building materials, it possesses unique advantages that glass and acrylic cannot match.

2. Performance Characteristics of PC Solid Sheet

Light Transmittance

PC Solid Sheet achieves a light transmittance of up to 89%, comparable to glass. Panels with UV coating will not turn yellow, fog or suffer deteriorated light transmission under sunlight. After ten years of service, its light transmission loss is only 6%, while PVC reaches 15%‑20% and fiberglass ranges from 12%‑20%.

Impact Resistance

Its impact strength is 250‑300 times that of ordinary glass, 30 times that of acrylic boards of the same thickness, and 2‑20 times that of tempered glass. It remains crack‑free when struck by a 3‑kilogram hammer falling from a height of 2 meters, earning it the nickname “unbreakable glass”.

UV‑Resistance

One side of PC Solid Sheet is coated with an anti‑ultraviolet (UV) coating that blocks UV rays, which can protect advertising canvases from UV damage.

Light Weight

Its specific gravity is only half of glass, cutting costs in transportation, handling, installation and supporting frames.

Flame Retardancy

According to the national standard GB50222‑95, PC Solid Sheet reaches Class B1, the first‑grade flame‑retardant standard. Its ignition point is 580℃. It self‑extinguishes once away from fire, produces no toxic gas during combustion and will not accelerate fire spread.

Bendability

It can be cold‑bent on‑site according to design drawings to form arches, semicircular roofs and windows. The minimum bending radius equals 175 times the panel thickness. Thermal bending is also available.

Sound Insulation

PC Solid Sheet delivers remarkable sound‑insulating performance, outperforming glass and acrylic boards of equal thickness. Under the same thickness condition, its sound‑insulation capacity is 3‑4 dB higher than glass. Internationally, it is a preferred material for highway noise barriers.

Energy‑Saving Performance

It keeps interiors cool in summer and warm in winter. PC Solid Sheet has a lower thermal conductivity (K‑value) than ordinary glass and other plastics. Its thermal insulation effect is 7%‑25% higher than glass of the same thickness, with maximum heat‑insulation improvement up to 49%. It greatly reduces heat loss and serves as an eco‑friendly material for buildings with heating facilities.

Temperature Adaptability

PC Solid Sheet will not become brittle at ‑100℃ nor soften at 135℃. Its mechanical properties show no obvious changes under harsh environmental conditions.

3. Differences Between PC Solid Sheet and Other Transparent Panels

Various building panels exist in daily life, and PC Solid Sheet is widely applied as an alternative material. Its advantages compared with other common building materials are listed below.

PC Solid Sheet vs Glass

Compared with glass, PC Solid Sheet features high strength, good plasticity and light weight. It resists violent impacts and hardly cracks for higher safety. Thanks to favorable plasticity, it can be bent into diverse radiances and shapes which are difficult for glass to realize.

PC Solid Sheet vs Acrylic Board

The most notable difference lies in fire performance. Though acrylic boards do not ignite spontaneously, they are highly flammable. In contrast, PC Solid Sheet has a high ignition point and self‑extinguishing property, making it an excellent lighting and fire‑proof panel.

PC Solid Sheet vs PC Hollow Sheet

There are no major property differences except for strength and weight. PC Solid Sheet adopts solid structure, while PC hollow sheet possesses single‑layer or multi‑layer hollow structure, so hollow sheets are not suitable for scenarios requiring high panel strength.

Comparisons above reveal the distinctions between PC Solid Sheet and other building panels. Such differences make PC Solid Sheet an irreplaceable product. The performance and application differences among glass, acrylic boards, PC hollow sheets and PC Solid Sheet are summarized above for industry reference.

4. Applications of PC Solid Sheet

Worldwide, PC Solid Sheet is developing toward high‑performance and specialized usage. Driven by surging domestic production capacity and market demand in China, the construction of large‑scale production lines and the booming automobile industry, China’s PC industry will step into a new development stage in the next few years. PC Solid Sheet is used across numerous sectors including construction, healthcare, electronics & electrical engineering, automobiles and sports equipment, greatly influencing people’s daily life and becoming an essential material for social progress. Its important status in various industries cannot be underestimated in future development.
