Laminated Glass
Laminated Glass
- Laminated Glass is made by placing PVB or EVA inter layer films between two or more sheets of annealed/heat strengthened/tempered glass.
- Under heat and pressure PVB or EVA melts and gets bonded completely with the chemical properties of two or more sheets of glasses making it a single sheet of glass. On breaking the PVB or EVA interlayer films prevent glass from shattering or falling down.
- The inter layer films PVB or EVA provide excellent protection from uv rays and sound waves.
- The Laminated Glass is used as safety and security glass for anti burglary, sound proofing. It also Provides protection from uv rays up to 98 -99%.
LAMINATION INTERLAYER FILM:
- EVA Interlayer Film and PVB Interlayer Film are used to make safety laminated glass.
- PVB stands for Polyvinyl butyral. It is made of polyvinyl alcohol by reaction with butyraldehyde.
- EVA stands for Ethylene-Vinyl-Acetate
GLASS LAMINATED WITH EVA INTERLAYER FILM CAN PROVIDE GREAT SAFETY AND SECURITY FEATURES :
- EVA is effective for reducing shattering when broken.
- EVA improves penetration resistance
- EVA reduces damage levels from natural disasters such as earthquakes, hurricanes and explosions
- EVA incorporated with PET film shows significant improvement in Anti- burglary properties
- EVA film owns high-performance safety function properties, it is reliable and produces long-time weather resistance.
- EVA has Significantly higher Adhesion with Glass and Polycarbonate
- Under Radiation and Aging tests, EVA is more stable than PVB
- EVA displays less hydrophilicity as compared to PVB and thus is widely used for outdoor open-edge applications
- EVA can be combined with other materials to improve the properties and also for decorative purposes. PVB's scope for the same is limited.
