VENTING MEMBRANES

Choosing an adhesive venting membrane rather than a threaded or screw-in system depends on key technical, industrial, and economic criteria. This is especially true in demanding sectors such as automotive, embedded electronics, and ADAS equipment.

• Ultra-compact design for space-constrained applications

GERGOVENT adhesive venting membranes feature an ultra-low profile. This design makes them ideal for applications with very limited available space, such as onboard cameras, automotive radars, ADAS sensors, and optical modules.
Unlike threaded or screw-in solutions, adhesive membranes require no drilling or mechanical inserts. As a result, they maximize internal space optimization and simplify integration into miniaturized housings.

• Fast and secure integration in production

An adhesive venting membrane enables quick, simple installation without the need for specific tools.
Assembly line benefits include:
– reduced installation time
– fewer human errors
– improved industrial repeatability
Consequently, manufacturers improve both productivity and quality in mass production.

• Reduced mechanical stress on housings

Threaded or screw-in systems generate tightening forces that may cause cracks in thin plastic housings or local deformation.
GERGOVENT adhesive membranes eliminate these risks because they apply no mechanical stress to the housing enclosure.

• Weight and volume savings (critical in automotive environments)

In the automotive industry, every gram matters. Even small weight reductions can improve overall vehicle performance. Adhesive vent membranes offer:
– reduced weight
– minimal footprint
– no additional mechanical parts
This represents a strategic advantage for embedded electronic architectures.

In summary, choosing a GERGOVENT adhesive venting membrane means prioritizing:
– optimized integration
– enhanced mechanical reliability
– reduced assembly costs
– sealing performance compliant with automotive standards
It is the most suitable solution for compact electronic housings exposed to demanding environments.

The resistance of an adhesive venting membrane to high-pressure (HP) water jets depends directly on three critical parameters:
– membrane design
– adhesive performance
– mechanical strength of the multilayer structure

Not all adhesive membranes on the market are engineered to withstand aggressive high-pressure jet environments, particularly in automotive applications.

Under high-pressure jet exposure, several phenomena can compromise sealing performance: adhesive lifting or peel-off, mechanical deformation of the membrane or loss of adhesion.
Generic membranes are typically not dimensioned to endure these extreme hydrodynamic stresses.

Exception: VM16 venting membrane from GERGOVENT 

Some high-performance technical membranes, such as the VM16 from GERGOVENT, are specifically developed to resist these severe conditions.

• Side Protect technology (patent pending)

The VM16 integrates an exclusive Side Protect design that limits the risk of lateral water ingress under high-pressure jet exposure.

• Reinforced multilayer structure

Its structure combines:
– ePTFE for breathability and hydrophobic barrier performance
– polyamide for mechanical robustness
This architecture provides mechanical resistance greater than 40 N, ensuring excellent peel strength.

• Very high-pressure jet performance

The VM16 membrane demonstrates resistance to water jets up to 200 bar. This clearly differentiates it from the majority of standard adhesive vent membranes.

Not all adhesive vent membranes perform equally under high-pressure water jets. A specifically engineered technical solution, such as the GERGOVENT VM16, is essential to guarantee:
– mechanical strength
– adhesion stability
– compliance with sealing requirements
– long-term durability
