- Overview
- Recommended Products
- Weight: Hollow sheets are lighter, approximately 1/3 to 1/5 the weight of solid sheets
- Thermal insulation: Hollow sheets offer significantly better insulation due to the air gap structure
- Impact resistance: Solid sheets have higher impact strength, making them better suited for safety and protection applications
- Cost: Hollow sheets are more economical with a better cost-to-performance ratio
- 4~6mm: Partitions, decoration, lightweight skylights
- 8~12mm: Greenhouse covers, standard roof daylighting, medium-span applications
- 12~20mm: Large-span roofs, sports venue skylights, highway noise barriers
- 20mm+: Special load-bearing or thermal insulation requirements
- Cold climates (Northeast China, Inner Mongolia, etc.): Select products with superior low-temperature toughness
- Hot climates (South China, Middle East, etc.): Choose sheets with excellent thermal stability and full UV coating
- High-altitude / high-UV regions (plateaus, islands, etc.): Must use double-side UV-coated products
- Class B1 (Combustion Classification: Non-combustible): Per GB 8624-2012 — standard for most building applications in China
- B-s1,d0,t0: Higher grade — no sustained burning after flame removal, no flaming droplets
- UL94 V-0: Per Underwriters Laboratories (U.S.) — stops burning immediately upon removal from flame

Q1: What is a PC hollow sheet, and how does it differ from a solid sheet?
A: A PC hollow sheet (also called PC sun sheet or PC hollow panel) is an extruded polycarbonate sheet with a uniform internal hollow cell structure. A PC solid sheet (PC solid panel / PC polycarbonate solid sheet) is a fully solid sheet without any hollow layer.
Key differences:
Q2: What is polycarbonate (PC), and is it safe?
A: Polycarbonate (PC) is a high-performance engineering thermoplastic known for its exceptional strength, toughness, optical clarity, and weatherability. It is widely used in construction, electrical and electronic equipment, automotive, medical devices, aerospace, and many other industries. PC material itself is non-toxic and odorless, compliant with food-contact material standards (such as FDA certification), making it safe for everyday use.
Q3: What are the advantages of PC sheets compared to glass and acrylic (PMMA)?
Section 2: Performance & Specifications
Q4: What thickness options are available for PC hollow sheets, and how do I choose the right one?
A: Common thicknesses: 4mm, 6mm, 8mm, 10mm, 12mm, 16mm, 20mm, 25mm.
Selection guide:
Q5: What is the light transmission rate of PC sheets, and how long before yellowing occurs?
A: Transparent PC hollow sheets offer approximately 75%~88% light transmission; solid sheets reach 88%~91%. High-quality PC sheets with dual-side UV coating typically maintain acceptable color stability (△YI ≤10) for up to 10 years under normal outdoor conditions. Standard products without proper UV protection may show noticeable yellowing within 3~5 years.
Q6: What temperatures can PC sheets withstand, and which climates are they suitable for?
A: PC sheets generally withstand -40°C to +120°C, with short-term resistance up to 130°C. They perform reliably in:
Q7: Are PC sheets fire-retardant, and what fire ratings do they achieve?
A: PC sheets have inherent self-extinguishing properties and can achieve the following fire ratings with flame retardant additives:
