Mirror grey Film For Daily Use uses special polymer materials to maintain structural stability in high temperature environments and avoid deformation or delamination caused by thermal expansion and contraction. During lamination and long-term use, the material shrinkage rate is extremely low, reducing the internal stress of the component and preventing the cell from cracking or packaging failure.
The gray film has an extremely low water vapor permeability, effectively blocking moisture from entering the component to prevent PID (potential induced decay) and corrosion problems. After long-term testing in high temperature and high humidity environments, it can still maintain excellent bonding strength and mechanical properties to avoid delamination or yellowing.
The mirror gray film adds high-efficiency ultraviolet absorbers and stabilizers to resist long-term UV radiation and avoid material embrittlement, powdering or decreased light transmittance. After ultraviolet accelerated aging tests, it can still maintain high reflectivity and surface integrity to ensure that the power generation efficiency of the component does not decay.
In coastal or industrially polluted areas, the gray film can resist corrosive environments such as salt spray and acid rain to avoid surface degradation or functional failure. The mirror surface is not easy to accumulate dust, which reduces the frequency of cleaning and reduces the power generation loss caused by stains.
In deserts or windy and sandy areas, the surface hardness of the gray film is high, which can resist the friction of wind and sand, and avoid scratches or fogging that affect the transmittance. It is not easy to crack under extreme temperature differences or mechanical stress, protecting the battery cells from microcracks.
Such as IEC 61215, IEC 61730 and other certifications, ensuring a service life of more than 25 years under various climatic conditions (dry heat, humid heat, cold zones, etc.). It performs stably in distributed rooftops, desert power stations, coastal projects and other scenarios without significant performance degradation.
