1）UV Resistance Function: One side of the polycarbonate sheet is coated with a UV-resistant layer, while the other side is treated to prevent condensation. This design achieves multiple functions including UV resistance, heat insulation and anti-dripping. It effectively blocks UV transmission, making it ideal for protecting precious artworks and exhibits from UV damage. 2）Light Weight：Its specific gravity is only half that of glass, thereby saving costs on transportation, handling, installation and related supporting structures. 3）Flame Retardancy：According to the Chinese national standard GB50222-95, this polycarbonate sheet is classified as a Class B1 flame-retardant material (first-level fire resistance). Its ignition temperature is 580°C (1076°F). It is self-extinguishing when removed from the ignition source, emits no toxic gases during combustion, and does not promote the spread of fire. 4）Flexibility：In accordance with design drawings, the sheets can be cold-bent on-site to form finished products such as arched structures, semi-circular roofs or windows. The minimum bending radius is 175 times the thickness of the sheet used. Hot bending can also be adopted as an alternative processing method. 5）Sound Insulation Performance：Polycarbonate sheets offer excellent sound insulation. Compared with glass and acrylic sheets of the same thickness, they provide superior sound reduction. At equal thickness, polycarbonate sheets reduce noise by 3–4 dB more than glass. Internationally, polycarbonate is widely used as a material for highway sound barriers. 6）Remarkable Energy Saving Effect：It keeps interiors cool in summer and warm in winter. The thermal conductivity (K-value) of polycarbonate sheets is lower than that of ordinary glass and other plastic materials. Its thermal insulation performance is 7% to 25% higher than glass of the same thickness, greatly reducing heat loss. This material is ideal for heated buildings and is also environmentally friendly. 7）Temperature Resistance：Polycarbonate panels do not become brittle or fragile at temperatures as low as -100°C, nor do they…

Polycarbonate (PC) is a colorless, transparent thermoplastic polymer with carbonate groups in its molecular chain. Classified by structure as aliphatic, aromatic or aliphatic‑aromatic, only aromatic PC is industrially produced, as other types have limited mechanical properties. PC features high transparency, heat resistance, superior impact strength, B1 flame retardancy and good processability. It outperforms PMMA in impact resistance and refractive index; flame‑retardant grades meet UL94 V‑0. PMMA remains lower‑priced, but the gap is narrowing as PC production scales up. Properties: PC has moderate wear resistance (surface treatments available). It withstands −100°C to 135°C with stable mechanical performance, but is not resistant to strong acids, alkalis or long‑term UV exposure. Avoid prolonged contact with water above 60°C. Widely used in construction, electronics, sound barriers and protective applications.

Polycarbonate sheet is a solid panel produced by melting and extruding polycarbonate pellets, with a general thickness ranging from 1 mm to 18 mm. Thanks to the inherent properties of polycarbonate, it features excellent flame retardancy, light transmittance, and temperature adaptability. Compared with other sheets, it has more outstanding advantages, especially superior impact resistance. One may ask: How strong is the impact resistance of polycarbonate sheet? Let’s look at the data: The impact strength of polycarbonate sheet is 250–300 times that of ordinary glass, 30 times that of acrylic sheet of the same thickness, and 2–20 times that of tempered glass. These figures are remarkable. For a clearer comparison, tests were conducted using sheets of the same thickness placed on the ground and impacted by hammers dropped from a height of 2 meters. The maximum bearable weight is as follows: Although not highly precise testing, it is clear that polycarbonate sheet is an excellent choice for applications requiring high impact resistance in outdoor environments. With these properties, polycarbonate sheet is widely used in: road sound barriers, basketball backboards, police riot shields, explosion-proof glass, and even transparent viewing panels in large aquariums. Besides impact resistance, polycarbonate sheet also offers flame retardancy, temperature resistance, anti-aging performance, light weight, and flexibility, opening up broad application possibilities. It can be expected that polycarbonate sheet will become increasingly common in daily life.

When it comes to high-performance building materials, PC polycarbonate sheet has become a top choice for builders, project contractors, and DIY enthusiasts around the world. As a professional PC polycarbonate sheet supplier with 15 years of export experience, we often get asked by overseas customers: What exactly is a PC polycarbonate sheet, and why has it gained such widespread popularity in the global market? Today, we will give you a detailed explanation, combining practical applications and product advantages, to help you fully understand this versatile material. What Is PC Polycarbonate Sheet? PC polycarbonate sheet, referred to as PC sheet for short, is a high-performance thermoplastic engineering material made of polycarbonate resin through extrusion, calendering and other professional processes. It is a kind of sheet material with excellent comprehensive performance, which is different from traditional glass, acrylic and other materials, and has unique advantages that are difficult to replace. To help you understand it more intuitively, we can compare it with common materials: In addition, PC polycarbonate sheet has good transparency (the light transmittance can reach 85%-90%, which is close to glass), and can be processed into various shapes such as hollow, solid, and corrugated according to different application scenarios, meeting the needs of different projects. Why Is PC Polycarbonate Sheet Popular in the Global Market? The reason why PC polycarbonate sheet can stand out in the global building materials market and be widely used in more than 50 countries and regions is closely related to its excellent performance and wide applicability. Here are the core reasons for its popularity: 1. Excellent Weather Resistance, Adapt to Various Climates One of the biggest advantages of PC polycarbonate sheet is its strong weather resistance. It can withstand extreme temperatures from -40℃ to 120℃, whether it is the hot and dry climate in the…

Today, you have most likely used products containing polycarbonate without even realizing it. This is because polycarbonate is nearly everywhere: it is widely used in eyeglasses, medical devices, automotive parts, lighting fixtures, DVDs, Blu-ray discs, and many other products. In fact, polycarbonate sheet is a transparent thermoplastic. It boasts extremely high strength and is nearly non-absorbent, enabling excellent resistance to impact and water erosion. Additionally, it is flame-retardant and chemically resistant. Two of the most remarkable properties of this sheet are its effective heat and cold insulation, with a temperature resistance range from -40°C to 130°C. Furthermore, it has a light transmittance of up to 88% and outstanding UV protection. As a result, PC Lite polycarbonate sheets are widely used in the construction of railway station roofs, greenhouses, pedestrian bridges, walkways, swimming pools, shopping malls, airports, and various other facilities. They are also commonly applied in exterior wall cladding and glazing systems. Why Choose Polycarbonate Sheets? Polycarbonate sheets have a high glass transition temperature (145°C–150°C). Combined with special UV co-extrusion technology that reflects infrared radiation and a multi-wall structure, they effectively reduce thermal conductivity. While similar materials deform at 70°C, polycarbonate sheets maintain structural integrity at temperatures as high as 120°C. Made from 100% virgin raw material and coated with an 80-micron UV-protective layer, these sheets can lower indoor temperatures by 10–15°C and prevent material degradation caused by high heat. They are suitable for nearly all daily applications. Are Polycarbonate Sheets Better Than Glass? At the same thickness, polycarbonate sheets outperform glass in impact resistance, weatherability, and flame retardancy. They are coated with a 50-micron UV-protective layer that effectively shields the sheet from UV damage. Polycarbonate sheets also offer excellent toughness and can be bent, making them adaptable to a wide range of scenarios. How to Maintain Polycarbonate Sheets? Regular…
