White TPT Backsheet laminates For Solar Panel Modules Encapsulation

1. High Weather Resistance
Through the accelerated ageing test of double-85 for 1000 hours, there will be non-delamination, non-cracking, non-foaming, as well as non-yellowing, no embrittlement after ageing by artificialultraviolet radiation exposure (QUVB) test for 3000 hours.

2. High Security
Security grade has passed the flame-retardant UL94-V2 flame-retardant grade. The UL flame spread index is less than 100, which effectively guarantees the module security features.

3. High insulation
TUV Rheinland of PD>=1000VDC (based on HFF-300), whichcan avoid electrical arcing module.

4. High Water Vapor Resistance
By infrared water vapor permeability tester, the water vapor permeability rates≤1.0g/m2.d.

5. High Adhesion
After the nano-plasma treatment, the surface energy of high fluoride levels can last 45mN/m or more within six months.

6. High-end Match

Suitable for large-scale photovoltaic power plants with the crystalline silicon cells module package.

7. High Compatibility
Good compatibility comes from the bonding with the other packaging materials of module.

8. High Efficiency
For its double-sided adhesion, there's no need to distinguish the backsheet's positive and negative when components packaging, which brings convenience for technicians.

9. High Flexibility
The adhesive data of the bone package for the module and EVA could be adjusted as per the clients'requirements.
