These long-lasting roll-up membranes are characterised by very thin walls and elastic materials with or without fabric reinforcement on the non-pressure side.
They are used in hydraulically and pneumatically operated control and regulation equipment, circuit breakers, boosters and measuring devices.
Membranes without fabric reinforcement are often used as separating elements in pressure compensators or as precision adjustment in gas pressure regulators.
The standard material is NBR, but on request they can be manufactured in VMQ, FPM and EPM with or without fabric. The elastomer sheet can also be purchased with the fabric to perforate the membranes and then form the fold and shape of the membrane.
