Shrink-N-Shield Infographic
  • Thin wall polyolefin is ideal for applications where space and weight is limited
  • UL-rated meeting UL 224, VW-1
  • Combines EMI shielding with heat shrink tubing for an all-in-one solution

Shrink-N-Shield® (TW) is an EMI shielding solution that features thin wall polyolefin heat shrink tubing and the Z-3250 shielding cloth. The thin wall polyolefin is lightweight and flexible, making this tubing ideal for applications that are limited with space and weight. The heat shrink is UL-rated for flame retardancy, meeting UL 224, VW-1, and has a 2:1 shrink ratio allowing for versatility in applications.

The Z-3250 shielding cloth is made of a taffeta fabric plated with copper then nickel for excellent corrosion resistance. The EMI shielding cloth will not flake or deteriorate over time, so you can be confident your wires or cables will have long-lasting protection from EMI, RFI, and EMF.

Shrink-N-Shield® (TW) is offered for diameters ranging from 0.875” to 1.25” and comes in 4-foot sticks, with custom sizes and lengths available upon request. The operational temperature range is -67°F to 257°F (-55°C to 125°C).
