Advantage
1. Moderate overflowing : Melt index 15-20;
2. Best optical performance and safety performance : 85-95% cross-linking at 120°C laminating.
3. Superior water-proof: open edge application
4. Best anti-aging and durability in outdoor application.
5. Crystalline particle control make EVA film more transparency and cleanliness.

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 +0.38mm EVA +5mm glass.
