Overview

Heavy wall heat-shrink tubing is UL-rated meeting UL 486D
EMI shielding fabric provides better protection from electromagnetic interference
Shrink ratio of 3:1 allows for versatility in application uses

Shrink-N-Shield® (HW) combines two proven technologies into a single, easy to install product for adding EMI shield protection to wire and cable bundles with diameters of 1/2" and less. Makes adding an EMI shield or secondary EMI shielding to wire and cable a snap. This product is comprised of SAE-AMS-DTL-23053/15 (w/o the adhesive layer) heat shrink tubing and Zippertubing's Z-3250 conductive cloth which has outstanding shielding properties. It is ideal for applications where thick, heavy wall insulation is needed for superior mechanical protection. This product has an operational temperature range of -55°C to 110°C. This product is supplied in four foot long sticks.

Features

Adhesive sticks to EMI shielding for easier installation and will outlast harsh conditions to ensure a long-lasting solution
Shields from EMI, RFI, and EMF
Operational temperature range of -40°F to 235°F (-40°C to 113°C)

Benefits

Heavy wall tubing protects from the toughest of conditions and environments
Z-3250-CN shielding fabric has a nickel coating for excellent corrosion resistance
Installation only requires a standard heat gun

Installation Instructions

FREQUENTLY ASKED QUESTIONS

Q: What lengths of Shrink-N-Shield
are available?

A: Shrink-N-Shield is typically provided in the industry standard 4 ft. long “sticks” of tubing. However, Zippertubing can provide pre-cut pieces of this material if required.

Q: My harness is longer than 4 feet, can I still use this product?

A: Sections of Shrink-N-Shield can be spliced together to create a longer EMI shield. Reference our installation
guide for instructions on how to do this, or speak with one of our design engineers for recommendations on covering longer cables.

Q: What do the 2:1, 3:1, 4:1 variations mean?

A: These shrink ratios refer to how much the material will change in size when heat is applied. To learn more, please refer to this article: Understanding Shrink Ratios of Heat Shrinkable Tubing.

Q: What diameter of tubing do I need?

A: Shrink-N-Shield products are identified by their starting diameter, before recovery or shrinking. It is recommended to choose a size that will result in a diameter equal to, or slightly smaller than, the cable it is covering to achieve a snug fit. For assistance with sizing, you can also contact one of our design engineers.

Q: How should I ground or terminate the ends of this tubing?

A: There are many different ways to terminate and ground Shrink-N-Shield. The Shrink-N-Shield installation guide outlines the three most common ways to ground the EMI shield including a wrapped drain wire, bonded grounding lead, and connector termination.

Q: My installed tubing has small wrinkles and ridges in it, is this normal?

A: Yes. As the tubing shrinks, the EMI shield material may gather more in certain areas than others. This is normal and does not affect the shielding performance of the tubing. If these cosmetic imperfections are an issue we recommend trying a smaller size of tubing.
