Lightweight products-transparent front plate(ZTT-KPX320T)

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.

Product  Features
  • Excellent UV resistanceIt is able to withstand aging under UV500kWh/㎡, 20-year service life of lightweight components ensured.
  • High transmittance retention rateThe transmittance retention rate after aging is above 95%,ensuring the long-term operation of components.
  • Excellent vapor barrierThe water permeability is less than 1.5g/(m2*day), ensuring the performance of the components.
  • High wear resistance, chalking resistanceTransparent wear-resistant PVDF film is used as the protective layer, ensuring excellent density and strong wear resistance.
