Parker Chomerics Products from Robert McKeown

A division of the respected Parker Hannifin Corp., Chomerics has been a leading innovator in the conductive elastomer field since 1961. Today, in addition to a variety of thermal interface products, Parker Chomerics manufactures a multitude of electromagnetic interference (EMI) shielding materials. Robert McKeown is proud to carry a number of Chomerics’ EMI shielding solutions, including:

CHO-FOIL EMI Shielding Tape

A versatile and cost-efficient EMI shielding solution, CHO-FOIL EMI Shielding Tapes from Parker Chomerics are available foil-backed in aluminum, copper, or tinned copper. These tapes are made with a highly conductive pressure-sensitive adhesive. Also available in embossed versions for applications in which aesthetics are a concern, CHO-FOIL is ideal for EMI cable shielding.

CHO-FAB EMI Shielding Tape

Made with the same highly conductive pressure-sensitive adhesive as CHO-FOIL, CHO-FAB is backed with nickel-plated cloth for strong corrosion resistance without any loss in conformability.

CHO-THERM Commercial Grade Thermal Insulator Pads

Available with or without adhesive, CHO-THERM Commercial Grade Thermal Insulator Pads are designed primarily for thermal conductivity but maintain some EMI shielding properties. CHO-THERM pads are available in fiberglass or polyimide (Kapton).

Low Closure Force EMI Strip Gaskets

Parker Chomerics’ Low Closure Force EMI Strip Gaskets — available in square, rectangular, D, P, and L shapes, among others, including custom options — are ideal for a range of commercial electronic enclosure EMI shielding applications. These strip gaskets can be manufactured from a variety of urethanes and urethane foams and are covered in a layer of nickel-plated silver-woven nylon.

Common applications include the doors, faceplates, ground pads, and seams of electronics panels that apply low closure force.

SOFT-SHIELD® 3500 EMI Strip Gaskets

Specialized low-closure force EMI strip gaskets, the SOFT-SHIELD® 3500 family of products is incredibly versatile.

These strip gaskets are available in more than 200 different profiles, with more under continual development. Conductive jackets can be constructed from a wide range of materials, including nickel-plated taffeta, nickel-plated rip-stop polyester, and halogen-free nickel-plated rip-stop fabric.

Below is a list of some benefits from SOFT-SHIELD® 3500 strip gaskets:

  • Reasonable cost
  • EMI shielding of more than 100 dB
  • RoHS compliance
  • REACH compliance
  • Very strong low-compression set properties
  • Strong abrasion and shear resistance in conductive jackets

THERM-A-GAP™ Filler Pads

Chomerics' THERM-A-GAP™ gap filler pads and sheets provide enhanced thermal conductivity for a wide range of applications including telecommunications equipment, lighting, automotive electronics, consumer electronics, semiconductors, and more. THERM-A-GAP™ thermal interface materials offer superior performance by filling air voids between PC boards, heat sinks, and other high temperature components.
