Vermalloy® is our exclusive magnetic shielding material for both secure voice and EMI protection.

Vermalloy® 622
A high permeability mumetal type alloy in standard stranded form. Used in critical shielding applications, especially in audio frequency ranges and high magnetic fields.

Vermalloy® 3948
A high permeability mumetal type alloy in flattened ribbon form. Provides up to 75% shield weight savings for critical airborne or satellite applications.

Other Braided Shielding

• Silver-coated Copper
• Nickel-coated Copper
• Aracon

Jacketing materials utilized by Vermillion include both braided and extruded types. The more common types are listed below.

Braided Jackets
Polyester, Nomex, Kevlar, PEEK and Fiberglass

Extruded Jackets
Polyurethane, Polyethylene (cross linked polyethylene for low smoke shipboard applications), PTFE, PFA and Tefzel - ETFE.

Blown On Jackets

• Neoprene
• EDPM
• Viton

Tinned Copper (T/C)
Most common and least expensive shielding material. Commonly used where magnetic shielding is not a requirement.

Ribbon Copper
Flattened form of T/C providing weight savings.

Mylar Wraps
Usually used in conjunction with copper or aluminum coating to provide an additional shielding layer. Uncoated mylar wrap can provide isolation as well as act as a binder to hold cable together during the manufacturing operation. Aluminum mylar generally provides cost, environmental and weight advantages while copper mylar provides flexibility, conductivity and higher frequency response advantages.
