Thanks to PP material's advantages such as safety, temperature resistance, moisture resistance and low cost, it has become an ideal choice in diversified fields. For example, it is a good choice for solar panel backsheets.
Core Benefits
Our PP FR boards possess excellent fire resistance, which can effectively block the spread of flames caused by circuit short circuits, reduce the fire risk of solar modules, and ensure the operational safety of outdoor power stations. Our products boast outstanding weather resistance and anti-aging performance, capable of withstanding environmental erosion such as outdoor ultraviolet rays and large temperature differences, preventing premature embrittlement of the backsheet, and extending the service life of solar panels to over 25 years. Besides, PP FR board features lightweight material (density approximately 0.9g/cm³) and good processability, allowing direct cutting and forming to reduce installation man-hours; its smooth surface is not easy to accumulate dust, lowering the cost of later cleaning and maintenance.
Key Performance Advantages
High-Temperature Resistance and Stability: The continuous service temperature can reach 100-120℃, and the short-term withstand temperature can reach 150℃. It can still maintain structural stability without deformation or melting under the summer sun exposure environment.
Electrical Insulation: The volume resistivity is ≥10¹⁴Ω·cm, which can effectively insulate the battery cells from the external circuit, avoid the risk of electric leakage, and ensure the stable electrical performance of the modules.
Chemical Corrosion Resistance: Can resist the erosion of corrosive substances such as acid rain and smog, without oxidation or degradation, maintaining the long-term protective performance of the backsheet.
