EMI Gaskets with conductive fabric or aluminium foil

Printer-friendly version

Our standard gaskets have a polyurethane foam core which is available in three different hardness values (soft, medium and hard). The foam core is covered with a conductive fabric with a copper-nickel metal coating. On request the core can also be covered with aluminium foil or other metal coated fabrics.

Production in our own plants

MTC fabric and aluminium over foam are manufactured in our own production plants in Germany and Asia.

We hold a UL94-V0 certification for our gaskets.

Our standard range includes a large range of sizes and shapes. Customized dimensions can be supplied at low cost at any time. The material can also be cut to the length you require or modified to suit your individual needs.

Our profiles are fitted with non-conductive adhesive tape as standard. The following other versions are available to order and for special applications:

Gaskets with conductive adhesive tape
Several adhesive tapes on a single profile
Adhesive tapes with removal aid (Wide Release Liner)
Small and miniature parts assembled on self adhesive paper (STP)

The fabric and aluminium over faom comply with the statutory RoHS regulations as do all of our other products.

Extensive possible uses

Fabric and aluminium gaskets with a foam core can be used for a wide range of applications and are suitable for the following:

D-Shape profiles

to compensate tolerances and uneveness in housing parts.
to bridge large gaps in the housing.
to connect a circuit board to the housing.
to interconnect several metal parts in the housing.
to connect shielding components to the housing (for example for monitors).
to connect LCD displays to the housing.
to connect socket and plug casings to the device housing.
to discharge electronic charges.

Performance features of our gaskets

In addition to their excellent shielding effectiveness (as high as over 80 dB @ 100 MHz – 18 GHz), our seals offer you the following benefits:

They are easy to work and can be cut with a pair of scissors.
They offer high resistance to wear.
Less connection elements are required between the housing components (thus reducing costs).
Low contact pressure forces mean that thinner metal plates can be used, which in turn reduces costs.
They have low surface resistance (< 0.08 Ohm).
Seals are a cost-saving method of shielding.
