Silicone membranes
Silicone membranes are precision technical components manufactured from silicone rubber with high thermal resistance, flexibility and dimensional stability. They are used as flexible diaphragms and seals in pumps, valves, pressure regulators, vacuum presses and process equipment. They ensure controlled pressure transfer, tightness and long-term operation in demanding chemical and temperature conditions.
What are silicone membranes used for?
Silicone membranes serve as flexible diaphragms and seals in industrial equipment. They enable precise pressure transfer, media separation and compensation of deformations in pumps, valves, regulators and vacuum presses.
What material are they made of?
They are made of silicone rubber (VMQ), which is characterised by mechanical stability, thermal and chemical resistance, and long service life under variable operating conditions.
At what temperatures can they operate?
Typical silicone membranes retain their properties over a wide temperature range, usually from approx. –50°C to +200°C, which allows them to be used in high-temperature and dynamic processes.
Are silicone membranes resistant to chemicals?
Yes, they exhibit resistance to many chemical factors, including oils, greases, ozone, moisture and atmospheric conditions. As a result, they perform well in applications requiring long-term tightness.
Where are silicone membranes most commonly used?
In mechanical engineering, pneumatics and hydraulics, in vacuum presses for laminating, in dosing equipment, as well as in applications requiring hygiene or biocompatibility.
Can silicone membranes be manufactured to size?
Yes, we offer membranes moulded or cut according to technical documentation, in various thicknesses, hardness levels and colours, tailored to a specific application.
