VE-S2 high transparent EVA film --the most transparency with best formula, can be used in solar cell encapsulation with superior durablity. Advanges: 1. Suitable melt index 15 easy lamination with solar panel. 2. Best optical performance and safety performance : 85-95% cross-linking at 130-150°C; 3. Superior water-proof: open edge application in outdoor 4. Outstanding anti-aging performance: heat and humidty resistance. 5. Perfect sunlight control and UV filtering. 6. Crystalline particle control make EVA film more transparency and cleanliness. Product Details: 1. The best mechanical performancet:
Cross-linking | Extracted in Xylene solution | >95%(after150°C25mins laminating) |
Tensile strength | | >18MPA |
Adhesion with glass | | >95N/cm |
Water absorption | | <0.1% |
2. Superior optical performance:
Light transmittance | >91% |
Haze | <0.2% |
UV filtering | >99% (390nm wavelength) |
Light transmittance decrease | <0.5%( 2000hrs UV radiation) |
Yellow index (YI) | <3 (2000hrs UV radiation) |
3. Best durability an stability in outdoor climate application: Heat and humidity resistance, Radiation resistance, ball impact peeling test and shot bag impact have been tested for laminated glass with norminal thickness according to GB15763.3-2009 safety glazing materials in building-Part3: Laminated glass.
Boilding test (2rhrs into 100°C water) | 5mm glass+0.80mm EVA+5mm glass | Good |
Heat and Humidty resistance test | 85°C 85%RH,1000hrs | Good |
Anti-aging test | 50°C 65%RH,UV radiation 2000hrs | Good |
Heat and cold shock test | -40°C30mins/80°C30mins, 50circles | Good |
Impact resistance against shot-bag | GB-15763.3-2009 | Qualified |
Ball impact peeling resistance | GB*15763.3-2009 | Qualified |
Laminating instructions: 1. Prepare and cut the EVA film into right size according to the following structure: glass+EVA film + glass 2. Put the overlapped glass into silicon bag and seal silicon bag well. 3. Activate vacuum pump for 5-8min till vacuum value reach -0.095Mpa to double checking the vacuum is good. 4 Set up the laminating temp. and time and start heating.The following data based on 5mm glass +0.40mm EVA +5mm glass.
| Heating speed | Temp. And holding time | Vacuum value |
First section | 2°C/ min | 60℃ | 25mins | -0.095MPA |
Second section | 2°C/ min | 80°C | 30mins | -0.095MPA |
Third section | 2°C/ min | 130°C | 45mins | -0.04MPA |
Remark: The above curves only for reference, the user should do some adjusts according to the process surroudings(temperature and humidity), glass area, glass thicknes,glass type and the machine itself. Packaging details: vacuum plybag+tinfoil paper+carton box+3/4rolls into one plywood box
