EMI/RFI Shielding – Electrically Conductive Elastomer ZIPSIL
Electrically conductive silicone elastomers ZIPSIL REP-01 series is a silicone rubber base with dispersed metal particles inclusions.
The electrically conductive elastomer has a low electrical resistivity and a very high microwave shielding efficiency (EMI-shielding).
Products from this electrically conductive elastomers can be of almost any shape, both flat gaskets and in the form of bundles.
Our product range of Electrically Conductive EMI-shielding Silicone ZIPSIL
Based on the electromagnetic shielding application and requirements of the EMC, we manufacture the following products from the electrically conductive elastomer ZIPSIL REP-01:
- Electricaly Conductive Elastomer Sheets ZIPSIL 101
- Electricaly Conductive Elastomer Extruded Profiles ZIPSIL 2xx series
- Electricaly Conductive Elastomer EMI Shielding Gaskets
Elastomer properties provide the highest electromagnetic compatibility, protection and anti- electromagnetic interference for the most demanding technical mean.
Basic applications of Electrically Conductive Silicone Elastomer ZIPSIL
- manufacturing of electrically conductive gaskets to provide EMI/RFI shielding and protection against electromagnetic interference
- environmental protection
- elimination of electromagnetic interference
- sealing enclosures of HF-radio devices
- grounding, antistatic protection
- waveguide flange sealing
Typically, the device’s shielding system consists of a conductive strip sandwiched between a metal case and a cover. The main function of elastomeric gaskets, profiles made of conductive silicone ZIPSIL REP-01 is to ensure sufficient electrical conductivity between the housing and the cover, based on the requirements for EMC and grounding, as well as to prevent possible ingress of moisture and liquids.
Our electrically conductive elastomer ZIPSIL REP-01 is a alternative to the electrically conductive elastomers of companies such as Laird Technologies, Parker Chomerics, Kemtron, Holland Shielding Systems BV and others.
