Shrink-N-Shield® (TW)

 One-Step Shielding and Jacketing Tubing, 2:1 Shrink Ratio, Polyolefin, Thin Wall Tubing
Shrink-N-Shield (TW) combines two proven technologies into a single, easy to install product for adding EMI shield protection to wire and cable bundles with diameters of 5/8" and less. Makes adding an EMI shield or secondary EMI shielding to wire and cable a snap. This product is comprised of a thin wall, 2:1 commercial heat shrink tubing and Zippertubing’s Z-3250-CN conductive cloth which has outstanding shielding properties. The product yields an outer jacket that is thinner than standard 2:1 tubing and is ideal for tight fit or close wire grouping applications. The product has an operational temperature range of -55 to 121ºC. This product is supplied in four foot long sticks and has a length tolerance of +/- ½ inch.
