Item | EVA(Ethylene Vinyl Acetate) | POE(Polyolefin) | Remarks |
---|---|---|---|
Vinyl Acetate Content (Vinyl Acetate)(wt%) | 28±4 | 0 | |
PID(Potential-induced degradation) Volume resistivity(Ω-Cm) | ≥1×1014 | ≥1×1016 | 100x ↑ |
Glass adhesion strength (N/cm) | 154 | 272 | 1.7x ↑ |
Degree of crystallinity (%) | 9.9 | 20.2 | 2x ↑ |
Moisture penetration rate WVTR(38℃×90% RH,500um)(g/m2-day) | 34 | 3.3 | 1/10x ↓ |
Improvement
Long-term reliabilityas a building material can be ensured by utilizing POE packaging materials.
- EVA(Ethylene Vinyl Acetate)
- PID(Degradation due to electrical potential difference)
- Delamination(Occurrence of moisture penetration/Delamination/thermal expansion)
- Corrosion (acetic acid)
- POE(Polyolefin)
- Anti - PID
- Significantly lower delamination due to low moisture penetration rate
- No Corrosion
