When choosing materials for outdoor, industrial, or commercial glazing, heat resistance is crucial—especially for businesses in high-temperature regions. Polycarbonate (PC) sheets are a top choice due to their ability to withstand heat without deforming or cracking. This article explains the key reasons behind their heat resistance, core properties, and why they outperform other materials—essential information for buyers and procurement teams. The Science of Polycarbonate’s Heat Resistance Polycarbonate’s heat resistance stems from its unique molecular structure and advanced manufacturing processes, which keep it stable at elevated temperatures. 1. Molecular Structure & Glass Transition Temperature (Tg) Polycarbonate features rigid aromatic rings and strong carbonate linkages in its polymer backbone, which resist heat-induced molecular movement. Its Tg (145°C-150°C/293°F-302°F) means it remains rigid well above the tolerance of most plastics. Unlike crystalline plastics, it softens gradually above its Tg and only becomes fluid for processing at 220°C-250°C, maintaining structural integrity even during short bursts of 130°C. 2. Heat Deflection Temperature (HDT) & Long-Term Stability Polycarbonate’s HDT (130°C-145°C under 1.82 MPa) is significantly higher than that of PVC (85°C) or ABS (60°C). Its Relative Thermal Index (RTI) of 221°F (105°C) allows continuous exposure for thousands of hours, with a long-term service temperature range of -40°C to 120°C—making it suitable for both high and low-temperature environments. 3. UV Coating & Multiwall Structures Outdoor-grade PC sheets are equipped with a co-extruded UV layer (80μm thick) that blocks UV rays and reflects infrared radiation, reducing heat absorption by 10-15°C. Multiwall sheets (twin-wall, triple-wall) have internal air pockets that act as insulation, lowering heat transfer and preventing warping—making them ideal for industrial and commercial applications. Polycarbonate vs. Other Materials Key Applications Polycarbonate sheets are widely used in the following applications: Tips for Maximizing Heat Resistance Choose the Right Polycarbonate Sheets Polycarbonate’s unique properties make it ideal for demanding high-temperature…

Solid polycarbonate (PC) sheets and traditional glass are mainstream transparent materials used in building lighting, equipment protection, and decoration. Both are light-transmitting and aesthetically pleasing but differ significantly in safety, durability, processability, and overall cost. This article simplifies their core differences to provide professional reference for accurate material selection. 1. Core Difference 1: Material Nature and Structure Material properties and structure determine their performance differences: Solid PC sheets are high-performance thermoplastic engineering plastics made from polycarbonate resin via extrusion. They have a solid, pore-free structure, are colorless, tasteless, and non-toxic, and high-quality products feature a UV protective layer for enhanced weather resistance[1][4]. Traditional glass is an inorganic non-metallic material produced by melting quartz sand, soda ash, and limestone. It is transparent but hard and brittle, lacks UV protection, and cannot be flexibly processed—even when tempered[2][5]. 2. Core Difference 2: Key Performance Comparison A simplified comparison of their key performances is provided below: Performance Dimension Solid Polycarbonate (PC) Sheets Traditional Glass Impact Resistance (Safety) Extremely tough and impact-resistant (250–300 times that of ordinary glass), with no sharp fragments when broken[1][5]. Brittle and easy to break, producing sharp fragments; tempered glass still poses safety risks[2][5]. Weather Resistance Excellent, UV-resistant, able to withstand temperatures from -40℃ to 120℃, with a service life of 15–25 years[1][4]. Poor, prone to yellowing and aging, with a service life of 5–8 years[2][5]. Light Transmittance 88%–92%, with soft light and slow transmittance attenuation[1][4]. Approximately 90%, with strong glare and significant transmittance decline over time[2][5].

With the growing demand for roof lighting, energy efficiency, and durability in the construction industry, polycarbonate (PC) lighting tiles and FRP (Fiberglass Reinforced Polyester) roofing materials have become mainstream choices for industrial plants, agricultural greenhouses, public buildings, and other scenarios. Both offer light transmission and light weight, but there are significant differences in material composition, performance, application scenarios, and long-term maintenance. This article briefly compares their core differences to provide professional reference for construction material selection and project procurement. 1. Core Difference 1: Different Material Compositions Differences in material composition are the root cause of all other discrepancies: Polycarbonate (PC) lighting tiles are made from polycarbonate resin through extrusion molding. High-quality products are co-extruded with a 50μm anti-ultraviolet (UV) layer on the surface, and some feature a hollow structure. They belong to the category of high-performance engineering plastics, which are environmentally friendly, durable, and free of toxic and harmful substance emissions[1][4]. FRP roofing materials, commonly known as fiberglass lighting tiles, are mainly composed of a surface film, unsaturated resin, and glass fiber. Unsaturated resin serves as the main base material, while glass fiber acts as a reinforcing agent. Styrene solvent is used in the production process; some inferior products may have slight residues of toxic substances, and the resin itself tends to decompose above 50℃, resulting in poor stability[1][4]. 2. Core Difference 2: Comparison of Key Performances A comprehensive comparison of the two materials across the core performance dimensions of roofing applications is provided below: Performance Dimension Polycarbonate (PC) Lighting Tiles FRP Roofing Materials Impact Resistance Extremely strong, known as “unbreakable plastic”—250 to 300 times stronger than ordinary glass. They are tough, resistant to breakage from hail or heavy impacts, and do not produce sharp fragments when damaged[5]. High in strength but insufficient in toughness, with much lower impact resistance…

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.
