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.
