Natural rubber membranes for vacuum presses

Any natural rubber sheet by Brevita Sia is designed to last under constant pressure and sustain multi-time elongation. No matter the challenge, it can improve your woodworking and lamination processes with:

Higher-than-average heat resistance – Our membranes can withstand temperatures up to 130°C for short periods, while other natural rubber pieces can only tough it out at 80°C.
Excellent durability – They are engineered with high-quality rubber and last longer than other types.
Perfect flexibility – Our rubber membranes are pliable, allowing for easy vacuum bed installation.
Low shrinkage – Natural rubber sheets by Brevita Sia shrink very little when exposed to temperatures during woodworking or composite applications.

Silicone membranes for vacuum presses

Silicone membranes by Brevita Sia are made of top-tier silicone, the industry standard for high-performance membranes and demanding vacuum-forming techniques. They are immune to temperature fluctuations and withstand high pressures and other environmental stresses over long periods.
You can buy vacuum membranes of the silicone type for solar panel production and thermoforming. These sheets have upgraded properties for high-temperature uses due to:

Good dimensional stability – Our silicone membranes won’t warp even in extreme conditions (up to 200°C) or high humidity. This makes them suitable for industrial applications where higher temperature levels are set.
Peerless elasticity – Silicone membranes have an excellent combination of strength and elasticity so that you don’t have to compromise one for another.
Non-toxic properties – Silicone is free from harmful chemicals, making it the perfect choice for sensitive environments and products.
Easy maintenance – The smooth and glossy surface of the silicone sheet makes it easy to clean on your vacuum press.

The silicone membranes for sale at Brevita Sia come pre-cut in multiple sizes (including extra-large ones) and are ready for use straight away. They are also designed with solid tensile properties described in our product data sheets.
