A Comprehensive Analysis of Hollow Board vs. Sunlight Board: Materials, Performance, and Application Scenarios


In the construction and packaging industries, hollow sheets and polycarbonate sheets are two relatively common types of plastic sheets. However, they have distinct characteristics and application scopes. This article will delve into the differences between the two—from the perspectives of material composition, performance, and application scenarios—helping you quickly grasp the key factors to consider when making your selection.


I. Material Differences: The Foundation That Determines Core Performance

Hollow board Made from polypropylene (PP), this material boasts environmental friendliness and recyclability, and is commonly used in both indoor and outdoor packaging as well as in lightweight construction applications. And... Sunlight panel (Also known as PC hollow sheets) made from polycarbonate (PC), which is an engineering plastic, these sheets feature high strength and impact resistance, and are specifically designed for harsh outdoor environments.


II. Performance Comparison: Light Transmittance, Thermal Insulation, and Durability

  1. Light transmittance

    • Hollow board has a relatively low light transmittance (around 50%–70%), and its surface tends to become cloudy.
    • The sunlight panel boasts a light transmittance rate as high as 89%, and its UV protection layer can maintain its light-transmitting performance over the long term.
  2. Thermal insulation

    • Hollow-core panels are mostly single-layer structures with a relatively high thermal conductivity, making rooms prone to overheating in summer.
    • The polycarbonate sheet features a multi-layer hollow design with exceptional thermal insulation performance, making it ideal for applications requiring heat retention, such as greenhouses and sunrooms.
  3. Durability

    • Hollow board has relatively weak compressive strength and is suitable for short-term packaging.
    • The impact resistance of polycarbonate sheets is 200 times that of glass, and their weather resistance can last for over 10 years.

III. Application Scenarios: Division of Areas with Distinct Advantages

  • Hollow board Widely used in indoor applications such as logistics packaging (e.g., turnover boxes, blade cards), advertising displays, and industrial protection. Its lightweight and foldable features help reduce transportation costs.

  • Sunlight panel It is primarily used in the construction sector—for outdoor projects such as skylights, greenhouse structures, and sound barriers. Its UV-resistant and flame-retardant properties meet stringent building standards.


IV. Price and Maintenance: Cost-Benefit Analysis

Hollow board prices are relatively affordable (about 4.5 to 20 yuan per square meter), but they require frequent replacement. Sunlight boards, on the other hand, have a higher unit price (80 to 200 yuan per square meter), yet they boast a long service life and low maintenance costs. You’ll need to weigh your budget and intended usage period when making your choice.


Conclusion: How to Choose?

  • Choose hollow board Suitable for situations with limited budgets, short-term use, and light packaging requirements;
  • Choose a polycarbonate panel. Suitable for long-term outdoor applications, where high light transmission and thermal insulation are required, and safety performance is a top priority.
