Recently, SDHX Advanced Materials Technology Corporation issued an announcement:
The patent of "high-strength and high-toughness PVDF solar back sheet film material and its preparation method" developed by the company won the gold medal of "film industry patent award".
This patent won the gold award because it solves the problem of insufficient strength and toughness of PVDF solar back sheet film in the prior art. By using this patented method, a PVDF back sheet film material can be obtained. The elongation, the tensile strength in the TD direction, and the elongation at break have been significantly improved.
At the same time, it has the remarkable characteristics of low light transmittance, high sunlight reflectivity, and high utilization rate of sunlight by the back panel assembly.
The high-strength and high-toughness PVDF solar back sheet film material that has won the patent gold award is the key material for the sustainable development of solar back sheets.
SDHX is China's national manufacturing "hidden champion" demonstration enterprise.
In 2020, the patent project of "perfluorinated ion exchange resin and its preparation method and application developed by the company" won the 21st China Patent Gold Award.
