Product Description

Vacuum silicone bag for vacuum laminated glass furnace
 

Product Description

ERBA silicone membrane is made with high quality silicone rubber on drum-type vulcanizing press or vulcanizing press according to the different request from the buyers. We erba depend on the advanced manage, innovative technique and strict quality control with excellent silicone rubber material and machine, ravel out the problem of lower smooth surface and high thickness tolerance of ROTOCURE vulcanizing machine, and also ravel out the problem of restricted width, length and visible joint on press vulcanizing machine. It is triumphantly without joint and with infinite length under the above mentioned excellence. We have the super-wide drum-type vulcanizing press with 4500mm width and high quality products maximum 4200mm width without joint. High quality silicone rubber with good performance of anti-aging, ozone resistance, heat-resistant, electric insulation, oil resistance, solvent resistance, corrosion resistant, nonpoisonous and tasteless, pollution-free. Working in air, water, oil and other medium at the temperature of -60° C - +260° C(moment maximum 300° C) with the high stability, reliability and surface inactive without sticky. Apply to punch all kinds of rubber seal gasket or special for PVC vacuum laminating press, wooden door vacuum laminating press, glass vacuum laminating press, solar vacuum laminating press, hot laminating press and card laminating press etc.

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.
