Shrink-N-Shield® (4:1)

3

a
A heat-shrink tubing that provides exceptional shielding from EMI, RFI and EMF, and has a 4:1 shrink ratio.
  • This product provide an easy, one-step installation and provides a lower total installed cost
  • Shrink-N-Shield (4:1) EMI shielding material offers better shielding effectiveness of 65 db from 10MHz to 10GHz
  • Excellent anti abrasive, environmental, chemical, and electrical properties with resistance to most oils and fluids, mild acids, and alkalis

Shrink-N-Shield® (4:1) has a 4:1 shrink ratio for components with diameters from 0.75” to 2”.

Shrink-N-Shield® (4:1) is an EMI shielding heat-shrink tubing that can be cut to length for versatile application uses. The flame-retardant and self-extinguishing polyolefin sleeve can withstand temperatures up to 275°F (135°C). Additionally, the jacketing has excellent abrasion, chemical, fluid and fungus resistance.

Shrink-N-Shield® (4:1) comes standard with the Z-3250-CN shielding cloth. However, other EMI-shielding cloths are available upon request.

The Z-3250-CN shielding cloth is made of a taffeta fabric plated with copper and 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.

Shrink-N-Shield® (4:1) is offered in diameters from 0.75” to 2” with custom sizes available upon request, and has an operational temperature range of -67°F to 275°F (-55°C to 135°C).

If you require a 2:1 or 3:1 shrink ratio, Zippertubing® offers Shrink-N-Shield (2:1) and Shrink-N-Shield (3:1), and if you have components with diameters as small as 0.015”, Shrink-N-Shield (Nano) is also available for your EMI shielding heat-shrink needs.

If your application is more suited to a wrap-around heat shrink for ease of installation, PRT® (S-3250) and PRT® (S-7200) are the solutions. Both standard products offer EMI shielding and can easily wrap around your wires or cables, rather than having to pull them through. If required, other EMI-shielding fabrics are available for PRT® upon request.

*Class III polyolefin heat-shrink tubing is available upon request.
