Professional Design Eva Pvb - Solar Backsheet – Xiaoshi Detail:

TPT (solar backsheet) symplectite coatings contain highly dispersed nano titanium silicide and high thermal conductivity materials, which greatly improve the High-FluoroCocrystal solar cell backsheet performance. The high scratching resistance gets rid of these shortcomings of traditional coating, such as the surface of anti-scratch performance is poor, during the coating operation it is easy to get scratches or peel off, thus affecting the backsheet anti-ageing properties, etc. The High Reflectivity improves the light’s second reflection, enhances module output power, and increases the competitiveness of client module.High Heat Dissipation improves power generation efficiency of the backsheet by accelerating heat dissipation.

Product description and advantages
High Fluorine created the interconnected penetrate technology of high fluorine symplectite, with organic integration of the multi-fluoride raw material——Enhance the anti-ageing capability, improves weather resistance. Ripple-free high-precision coating technology makes coating of the surface smooth, and the uniform consistent——Enhance the density of the surface coating, improves electrical insulation properties. Nano-titanium silicide plasma processing techniques to enhance durable surface energy——Upgrades package compatibility, improves adhesion of EVA and silicone binding agent
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 artificial ultraviolet 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), which can 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.
