Shrink-N-Shield® (FE)
  • EMI shielding fabric provides better protection from electromagnetic interference
  • Viton® heat shrink meets MIL-DTL-23053/13 and MIL-R-46846, Type III, Class 1
  • Heat-shrink tubing provides the best resistance to abrasion and offers the best flexibility

Shrink-N-Shield® (FE) combines two proven technologies into a single, easy to install product for adding EMI shield protection to wire and cable bundles with diameters of 1.0" and less. Makes adding an EMI shield or secondary EMI shielding to wire and cable a snap. The product is comprised of SAE-AMS-DTL-23053/13 flexible Fluoroelastomer heat shrink tubing and Zippertubing's Z-3250 conductive cloth which has outstanding shielding properties. The outer tubing is a high temperature, rubber-like jacket which is highly fluid resistant and flame retardant. The operational temperature of this composite product is 175°C, but it can withstand short spikes to 200°C. This product is supplied in four foot long sticks.
