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%.
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.
