Overview

Offers good EMI shielding (30 MHz to 1 GHz)
Flexible and lightweight—ideal for the aerospace industry
Flame retardant and meets UL1441, VW-1

Flex-Shield™ (HP) is a high-flexing, EMI-shielding sleeve. It is made of two-ply twisted meta-aramid (Nomex) threads that have tin-plated copper foil strips helically wound around each thread, then braided together to create the expandable tubular sleeve. Flex-Shield™ (HP) is extremely flexible yet thin, with a material thickness of only 0.025”. Because it can expand or shrink considerably, Flex-Shield™ (HP) can work on applications that fluctuate in sizing. The expandable sleeve has a wide temperature range of -40°F to 302°F (-40°C to 150°C) and is RoHS compliant, fluid resistant and UL-rated for flammability, meeting UL1441, VW-1 specifications. Flex-Shield™ (HP) can be equipped with a woven-in braided wire for grounding needs.

Flex-Shield™ (HP) is currently being utilized for a variety of aerospace applications. Due to its lightweight and non-metallic core material, Flex-Shield™ (HP) is the “Aerospace Ace,” providing EMI shielding and a durable barrier between components and environmental conditions. Flex-Shield™ (HP) is available in sizes ranging from 0.125” to 1.5” in diameter, with custom sizing available upon request.

Installation Instructions

FREQUENTLY ASKED QUESTIONS

Q: What lengths of Flex-Shield jacketing are available?

A: Typical spool lengths for most sizes are 328 feet, but custom lengths can also be provided.

Q: How is Flex-Shield different from traditional metal braid?

A: Like traditional metal braid, Flex-Shield uses tinned copper as the conductive shielding material. However, the tinned copper is wrapped around a lightweight fiber core rather than using solid metal wire strands. This construction makes Flex-Shield lighter and more flexible while still providing effective EMI shielding.

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

A: There are many different ways to terminate and ground Flex-Shield. Our termination and splicing guide offers some common techniques. Additionally, Zippertubing design engineers can assist with recommendations to suit specific or custom grounding applications.

Q: My wires keep getting caught while I’m pulling them through Flex-Shield. Is there an easier way?

A: Yes. Try bundling the wires together and wrapping the leading end with tape to create a smooth, tapered profile. This helps prevent individual wires or connectors from catching on the braided sleeve. For longer lengths, a pull wire can also be routed through the Flex-Shield first and secured to the taped wire bundle to help guide it through. Slightly compressing the Flex-Shield will expand its diameter and provide additional room during installation.

Q: Can I cut the tubing?

A: Yes. Standard scissors are suitable for cutting through Flex-Shield sleeves.

Q: How can I prevent the ends of Flex-Shield from unraveling?

A: Secure the cut ends with tape, heat shrink tubing, or another suitable method to keep the braid constrained. The ends can also be folded inward to contain the cut edge and help prevent the sleeve from unraveling.
