Silicone Vacuum Bag for Glass Laminating Furnace Oven

Silicone Vacuum Bag for Glass Laminating Furnace Oven Silicone Vacuum Bag for Glass Laminating Furnace Oven Silicone Vacuum Bag for Glass Laminating Furnace Oven Silicone Vacuum Bag for Glass Laminating Furnace Oven
Product name:Silicone Vacuum Bag for Glass Laminating Furnace Oven

Each set of vacuum silicone bag consists of one top and one bottom silicone sheets. The top and bottom silicone membrane sheet edges are sophisticatedly embedded to each other, to make sealed room for vacuuming. Interlocking of edges and corners are easy. Edges and corners are specially modified , such as locking strength grows larger when vacuum pressure becomes higher. Although it is tightly sealed, edges unlocking and opening are amusingly easy when vacuuming stops.

Product Features
heat-resistant, high elasticity, special surface property (no adhesion) and physiological inertia, oil resistant, solvent resistant, anti-aging, anti-corrosive, and non-polluting, EVA resistance.

Tensile Strength
Top silicone blanket is more flexible. When vacuum is turn on, air in between top and bottom silicon sheets starts to evacuate. Top silicone blanket begins to wrap downwards along glass edges until it gets in physically zero-gap contact with bottom silicone sheet. No air or gap is allowed in between the two silicone blanket. This specially formulated silicon blanket is highly elastic. It provides enough flexibility, allowing the blanket to stretch until it fully wraps along glass edges. This remarkable property is especially important when glass is thick and/or curve.

Heat Resistance
Silicone sheet resists high temperature(more than 220C). Uniform Heating is applied on silicon blanket and glass all the time until interlayers, for example, EVA film is melted thoroughly. High temperature resistance is one of the important criteria of silicone vacuum blanket.

Thermal Stability
After heating is completed, forced cooling is started. Silicon is thermally stable for numerous rise and fall of temperature.

Silicon blanket is tough. It allows glass loadings and unloading for numerously times. It resists abrasion, wear and tear up to a certain high degree. But to protect the silicone vacuum bag, it’s better you edging the glass before laminating.
While the blanket is strong, the blanket is also soft enough for easy handling when top blanket is opened and closed during glass loading and unloading.
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 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

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.
