In order to ensure the weather resistance of lightweight flexible components, transparent front plate products are introduced, capable to replace the front glass.The good vapor barrier ensures that the components can still maintain stable operation in wet environment;due to the high transmittance retention rate and perfect UV barrier, the transmittance retention rate is still high after various weather resistance tests, ensuring the long-term and efficient operation of the components.
Accompanied by the fluorine film independently developed by our company, the wear resistance and chalking resistance of the front plates have been effectively improved.
