Silicone Vacuum Blanket/Bag for EVA PVB Glass Laminating Furnace Oven


Each set of integrity silicon blanket consists of one top and one bottom silicone sheet. The four top and bottom 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.

Tensile Strength ≥11.2 Mpa

Tearing Strength ≥38N/mm

Long Run Temperature 250℃

EVA PVB Resistance Strong

Normal Using Life >3000 cycles

Appearance One side smooth and one side cloth

Remarks Maximum width: 4000mm without joint, the world’s first


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 PVB resistance.


Tensile Strength Top silicone blanket is more flexible. When vacuum is turn on,

the air in between top and bottom silicon sheets starts to vacuuming. 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 250C).

Uniform Heating is applied on silicon blanket and glass all the time until interlayers, for example, EVA PVB 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 more than 5000 cycles 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 Blanket/Bag, it’s better you edging the glass before laminating. Or put some high temperature mesh/ cloth inside the silicone blanket to help vacuuming and protect the silicone blanket.

While the blanket is strong, the blanket is also soft enough for easy handling when top blanket isopened and closed during glass loading and unloading.


Thanks to special formula, silicon blanket is deterioration proof. Its properties retain unchanged.

When the blanket is always kept clean, handled properly and glass edge is polished, the blanket life is long lasting.

Silicon tube of highly flexible silicon tube is provided. It connects from silicon blanket to vacuum system. Air in between top and bottom sheets is flowed through this silicon tube to vacuum system. 4 meter of silicone tube will be provided with each vacuum hose. And the location of vacuum hose is cusotmization available.
