Shrink-N-Shield Infographic
  • Double layer of EMI shielding cloth provides 99% shielding coverage
  • MIL-SPEC polyolefin heat shrink tubing
  • 2:1 shrink ratio offers versatility in application uses

Shrink-N-Shield® (2X) is an EMI shielding heat shrink tubing that provides exceptional protection from EMI, RFI, and EMF. The MIL-SPEC heat shrink meets MIL-DTL-23053/5C, as well as being UL-rated with meeting UL224, VW-1, making this solution ideal for military and aerospace industries. The polyolefin tubing is flexible, abrasion resistant, and self-extinguishing. The heat shrink also has excellent fluid and fungus resistance to applications that are exposed to such elements. The 2:1 shrink ratio allows for versatile application uses, and the tubing allows for the ability to be cut to any desired length.

Shrink-N-Shield® (2X) is equipped with a double layer of EMI shielding cloth for exceptional protection. The Z-3250 shielding cloth is made of a taffeta fabric plated with copper then nickel for excellent corrosion protection. The lightweight, flexible shielding cloth will not flake or deteriorate over time, so you can be confident your components will have long-lasting protection against EMI, RFI, and EMF. The dual layer of Z-3250 provides 99% coverage for applications that desire more shielding than the standard EMI shielded heat shrink Zippertubing® manufactures.

Shrink-N-Shield® (2X) is offered for diameters ranging from 0.1875” to 1.5”, with custom sizes available upon request. The operational temperature range is -67°F to 275°F (-55°C to 135°C).

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.
