Conductive-Elastomer-Molded-Gaskets

Conductive Elastomer Molded Gaskets

Parker Chomerics can mold conductive elastomer EMI gaskets to fit practically any application.

Product Highlights:

  • Optimizing elastomer gasket designs
  • Allowing accurate predictions of alternate design concepts
  • Eliminating part and tooling charges as well as extensive trial and error prototype evaluation

STANDARD PARTS

Parker Chomerics produces molded conductive elastomer EMI gaskets in hundreds of standard sizes in the following forms:

  • O- and D-rings, flat washers
  • Connector Gaskets – Interfacial Mil Spec (MS) connector seals; Dsubminiature rectangular; Jam-nut seals
  • Waveguide Gaskets – Molded circular and rectangular (O or D cross section)

CUSTOM MOLDED ELASTOMERIC SHAPES

Parker Chomerics can mold conductive elastomer EMI gaskets to fit practically any application. With our range of high quality materials and efficient manufacturing systems we can provide attractive choices in price and performance.

Parker Chomerics engineers can rapidly optimize gasket designs (at little or no cost), using tools such as finite element analysis (see next page). Prototype development, tooling and part delivery are performed to meet our customers’ requirements, with adherence to the industry’s highest quality standards.

Custom elastomer gaskets can include tight corners, retention bumps, ribs and other special geometries Many other features can be added, such as fabric or mesh reinforcement, pressure-sensitive adhesive, and compression stops. Non-conductive environmental seals can be bonded to or co-molded with conductive EMI shielding elastomers. Contact Parker Chomerics Applications Engineering Department to discuss how custom conductive elastomer shapes can be designed to meet your application requirements. Table 1 provides general tolerances for molded conductive elastomer gaskets.

FINITE ELEMENT ANALYSIS

Parker Chomerics specializes in elastomer finite element analysis (FEA), using the MARC K6 Series software as a foundation of FEA capability.

Benefits of FEA include::

  • Optimizing elastomer gasket designs
  • Allowing accurate predictions of alternate design concepts
  • Eliminating part and tooling charges as well as extensive trial and error prototype evaluation

This advanced computer simulation technology enables compression/ deflection characteristics and other parameters to be evaluated and optimized during the design phase, without the delays of trial-and-error prototyping. FEA is routinely employed in the development of Molded- In-Place Cover Seals.

For additional information contact our Applications Engineering Department. ments. Table 1 provides general tolerances for molded conductive elastomer gaskets.

SIZE LIMITATIONS

Parker Chomerics can produce Molded-In-Place gasket/panel assemblies in any overall dimension larger than ¾ x ¾ in. (19 x 19 mm). Minimum recommended gasket profile cross section is 0.062 in. (1.6 mm), with a minimum thickness of 0.020 in. (0.5 mm) for flat gaskets. Smaller cross sections and thicknesses, although not recommended, can be accommodated.emi gaskets--EMI-RFI Shielding Products--Conductive Elastomer Molded Gaskets 1

FIGURES 1a-c
A typical use of FEA in designing molded gaskets is the evaluation of force and deflection needed for proposed designs. The FEA shown in Figure 1a, performed on the cross section in Figure 1b predicts the gasket’s deflection characteristics and compression requirements reported in Figure 1c.
