Product Description
Innovative Composite Structure Design
The TPCw2 backsheet is manufactured using precision multi-layer composite technology:
1. Weather-resistant layer using DuPont PVF fluoropolymer film:
- Thickness precisely controlled within 125±5μm range
- Incorporates high-efficiency UV absorbers and stabilizers
- Specially treated surface enhances interface bonding
- Certified through IEC 62788-2 standard testing
2. Bonding layer utilizing patented fluorinated coating curing technology:
- Special fluorocarbon resin forms 3D cross-linked structure
- Unique molecular design improves interface bonding strength
- Initial peel strength ≥80N/cm
- Validated by 3000-hour dual 85 (85°C/85%RH) aging tests
Exceptional Long-Term Reliability
1. Environmental durability performance:
- UV aging resistance >200kWh/m², exceeding industry standards
- Stable performance after 4000-hour damp heat aging
- No abnormalities after 300 thermal cycles (-40°C~85°C)
- No corrosion after 1500-hour salt spray test
2. Mechanical performance assurance:
- Initial tensile strength ≥110MPa
- Tensile strength retention ≥90% after aging
- Elongation at break >130%, ensuring installation reliability
- Interlayer peel strength >8N/mm, preventing delamination risks
