10mm / 16mm / 20mm High Light Transmission Polycarbonate Hollow Sheet SGS Tested Polycarbonate Hollow Sheet

1.Innovative Hollow-Core Design: The internal multi-cell (2-layer, 3-layer, 4-layer, or even more) structure not only reduces the sheet’s weight by 30%-50% compared to solid sheets of the same thickness but also creates air-filled cavities that act as excellent thermal insulators. This design effectively blocks heat transfer, keeping indoor spaces cooler in summer and warmer in winter, thus lowering energy consumption for heating and cooling.

​

2.Superior Impact Resistance: Especially for polycarbonate (PC) hollow sheets, the material boasts impact strength 250-300 times that of ordinary glass and 30 times that of acrylic sheets. It is shatterproof and can withstand harsh conditions like hail, strong winds, or accidental impacts, ensuring long-term structural integrity.​

3.Excellent Light Transmittance: Transparent or translucent hollow sheets (e.g., PC variants) offer 70%-90% light transmittance, comparable to glass. They diffuse sunlight evenly, avoiding glare while providing sufficient natural illumination—ideal for applications requiring bright, soft lighting.​

4.Strong Weather Resistance: With UV-resistant coating (often co-extruded on one or both sides), hollow sheets resist yellowing, aging, and embrittlement caused by long-term exposure to sunlight, rain, snow, or extreme temperatures (-40℃ to 120℃ for PC types). Their service life typically ranges from 10 to 20 years with proper maintenance.​

5.Lightweight & Easy Installation: Weighing only half of glass, hollow sheets reduce the load on supporting structures (e.g., roofs, frames) and simplify transportation and installation. They can be easily cut, drilled, or cold-bent into curved shapes (minimum bending radius depends on thickness) to fit custom design needs.​

6.Sound Insulation & Fire Retardancy: The hollow cavities absorb sound waves, providing better sound insulation than solid sheets or glass (reducing noise by 5-10 dB). Most PC hollow sheets meet international fire safety standards (e.g., UL 94 V-2, GB 8624 B1), being self-extinguishing and non-toxic when burned.
