Detail Information:
VE-H high transparent EVA film --the best mechanical performance product with best formula and best material. Can be widely used in architectural safety glass, bullet-proof glass, anti-explosion glass etc.
Product specification:
0.40mm*2300mm*100m; 0.80mm*2300mm*50M;
0.40mm*2100mm*100m; 0.80mm*2100mm*50M;
Advanges:
1.Superior stability after breakage and High fracture integrity.
2.Cross-linking :85-95% (130-150°C)with good heat&humidty resistance.
3. Less overflowing: Milt index 5-6;
4. Superior water-proof: Open edge application
5. Better Sound insulation
6. Perfect sunlight control and UV filtering.
7. Crystalline particle control make EVA film more transparency and cleanliness.

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.
