Beryllium copper gasket, BeCu

Beryllium copper EMI gasket has superior mechanical resilience and good conductivity. This makes it ideal in applications where hatches and doors are frequently opened and closed.

These are available in profiles and dimensions for most EMI shielding applications including grounding.

These can also be plated in different metals to avoid galvanic corrosion and provide good shielding properties.

Dispensed conductive gasket

Conductive or non-conductive elastomeric silicone compound can be dispensed directly as a gasket in XYZ direction using CNC technology.

Dispensing is often used where there is little space for the gasket, where you can't fit traditional gaskets.

Don packings

We have tool sets for several different types of gaskets. Various materials are available to meet the requirements for EMI shielding, environmental sealing, galvanic compatibility and fuel/oil resistance.

expanded and woven metal with neoprene, silicone or fluorosilicone

A composite of metal impregnated with an elastomer provides a good combination of high conductivity and environmental sealing.

The gasket is suitable for a good EMI/RFI shielding while providing a good environmental seal. There is metal made of woven aluminum wires, expanded aluminum or monel impregnated with silicone, fluorosilicone or neoprene.

Expanded monel wire is also available without impregnated elastomer for those who do not need environmental sealing. The material can be purchased in sheets or in pre-cut gaskets as required.

These gaskets are suitable in applications where tolerances do not exceed 0.1 mm and/or where space restrictions exist. These gaskets are suitable as plug gaskets.

Conductive silicone and fluorosilicone gaskets

Conductive elastomers are fully post-cured silicone or fluorosilicone doped with electrically conductive materials to provide low resistive contact between the interface materials.

There are many different choices of fillings to avoid galvanic corrosion between surfaces.

Many different extruded profiles are available in running length or made to customer specifications such as stamped gaskets or vulcanized O-rings.

Conductive elastomers are most often used where space is limited and where good shielding and environmental sealing, IP class, is required.

Fluorosilicone is used when the application has to resist e.g. different fuels.

Conductive fabric gasket or fabric over foam

This shielding gasket is made from a synthetic polyester or nylon thread that is plated with nickel/copper, silver or similar to provide a conductive layer.

The fabric is then wrapped around a foam or other rubber in many different dimensions and shapes.

This conductive gasket can be used in many different applications, but preferably for indoor use.
Most meet UL94V-0 requirements and are available in lengths, cut or punched.

Oriented wires in silicone or fluorosilicone

A flat silicone rubber gasket is available in solid or sponge and these contain threads of monel or aluminum. The threads stand vertically and the gasket feels like 'beard stubble'.

This gasket is environmentally sealed and shields well when compressed between two metallic surfaces.

Excellent EMC/EMI properties are achieved because there are 900 wires per square inch (25 mm²).

This material has many uses as it can be supplied in strips, sheets or as a customized gasket in different thicknesses such as punched gaskets. The gasket can also be supplied with tape for easy assembly.

This gasket should not be used in applications where the gasket must return to its original shape after compression.

A fluorosilicone version is also available if the gasket is used in environments with fuel, oils, hydraulic fluids or similar.

Knitted gaskets

Knitted gaskets are a cost-effective solution for good shielding in the magnetic and electric fields including EMP.

The gaskets can be supplied either as a knitted metal gasket or knitted around an elastomeric core (such as silicone, neoprene or similar) to return to its original shape after compression.

There are different choices of wire materials such as aluminum, monel, TCS (Tin Plated Copper Clad Steel) or stainless steel. The choice of wire material is to avoid galvanic corrosion between the surface and the gasket.

Standard profiles are round, round with fin and rectangular. D-shaped and other customized shapes are also available. These gaskets can be supplied in different lengths or as finished frames or similar.

To achieve a certain IP class, we can also supply a knitted gasket glued on the side with an environmental gasket.

All these knitted gaskets can be delivered in running meters or as customized gaskets. They can also be supplied with compression stops to avoid over-compression.
