For 3D laminated products, silicone membranes are typically used for various vacuum presses. These membrane sheets firstly transfer heat to the components more rapidly, and secondly they apply positive pressure on top of the components to press the material while the vacuum on the bottom of the press can also have suction.

Silicone membranes are flexible, durable and heat-resistant materials made of high strength quality silicone rubber. They can be used as re-usable vacuum membrane materials for a variety of appications, such as in the woodworking, composites, sublimation, solar, and glass industries.
