EVa glass film

详情

EVA laminated glass film
EVA laminated glass is a kind of safety glass, two or more layers of glass sheets bonded together using a kind of hot melt adhesive film (EVA or PVB film) under pressure and vacuum.    
The glass fragments will stick tightly to the interlayer EVA film even glass is broken and won't fall down to injure the body.
Thicknesses: 0.*5mm, 0.*8mm, 0.*6mm
Colors and Transparencies:
From standard clear to super clear
From light white to deep white
From transparent red to transparent black
From translucent orange to translucent blue
From opaque yellow to opaque purple 
Advanges: 
1. Less overflowing : lower Milt index **6;
2. Best optical performance and safety performance : ****5% cross-linking at ***- **0°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.
 
Product  Details: 
1. The best  mechanical performancet:  
Cross-linking    Extracted in Xylene solution               >*5%(after**0°C*5mins laminating)            
Tensile strength         >*1MPA
Adhesion with glass         >*5N/cm
Water absorption         <0.1%
 
2.  Superior optical performance:
Light transmittance    >*1%    
Haze    <0.2%
UV filtering    >*9% (**0nm wavelength)
Light transmittance decrease    <0.5%( ***0hrs UV radiation)
Yellow index (YI)    <3      (***0hrs 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 GB****3.*****9 safety glazing materials in building-Part3: Laminated glass. 
Boilding test (2rhrs into **0°C water)    5mm glass*0.*0mm EVA*5mm glass       Good  
Heat and Humidty resistance test    *5°C *5%RH,***0hrs       Good
Anti-aging test    *0°C *5%RH,UV radiation ***0hrs        Good
Heat and cold shock test    **0°C*0mins/*0°C*0mins, *0circles       Good
Impact resistance against shot-bag    GB*****3.*****9      Qualified
Ball impact peeling resistance    GB*****3.*****9      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 **8min till vacuum value reach *0.**5Mpa to double checking the vacuum is good.  
   4. Set up the laminating temperature and time  and start heating. The following data based on 5mm glass *0.*0mm  EVA *5mm glass.
     Heating speed    Temp. And holding time    Vacuum value
First section    2°C/ min    *0℃    *5mins    *0.**5MPA
Second section     2°C/ min    *0°C    *0mins    *0.**5MPA
Third section    2°C/ min    **5°C    *5mins    *0.*4MPA
Remark:  The above curves only for reference, the user should do some adjusts according to the process conditions (temperature and humidity), glass area, glass thickness, glass type and the machine itself.
