VE-H ultra clear EVA laminated glass film / EVA foil for glass lamination -- the best mechanical performance and impact-resistance , less overflowing film at edges after laminating. Recommend application: bullet-proof glass, exposive-proof galss, curtain wall, floor, showwindow etc. Roll 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 Perfect sunlight control and UV filtering. 6. Crystalline particle control make EVA film more transparency and cleanliness. Product Details: 1. The best mechanical performancet:

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 | 135°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. Certificate: SGS and ISO9001 and EN ISO 12543-4:1998 made by our agent
