CHO-SHRINK electrically conductive heat shrink cable transitions/splitters are available in two performance options: CHO-SHRINK 1061, coated with silver, designed for higher end military and aerospace applications, and CHO-SHRINK 1120, coated with silver-plated copper, and designed for commercial applications. Both provide lightweight cable and connector EMI shielding with easy installation and assembly by conventional heat guns and ovens. CHO-SHRINK transitions are available with and without an adhesive lining, which melts when the transition is heated and bonds to the underlying surface, creating a water-resistant seal.

Both CHO-SHRINK materials are ideal for any applications where weight savings associated with EMI cable shielding is of paramount importance. The product consists of polyolefin heat shrinkable transitions/splitters that are coated with Parker Chomerics unique silver or silver-copper plated filled coating systems. CHO-SHRINK cable transitions/splitters are available coated only inside.

The CHO-SHRINK cable shielding system includes tubing, connector boots, cable transitions and boot adaptors – and allows for relatively easy assembly of shielding systems for complex cable wiring harnesses using conventional heat shrink tubing heating devices.
The system offers excellent shielding and significant weight savings over traditional metal braid cable shielding systems. In addition, CHO-SHRINK offers an environmental shield against dust, moisture and other contaminants. CHO-SHRINK remains flexible to support any needed cable routing. Easy repair or rework of cables is facilitated by cutting off the CHO-SHRINK material and installing new material.

CHO-SHRINK materials are ideal for installation on cabling for medical device electronic assemblies which require reliable EMI shielding performance and may benefit from silver’s antimicrobial properties. Typical applications can include; missiles, aircraft, satellites, vehicles, and on cables of any other electronics systems where weight savings is mandatory.
