ENABLING CONDUCTIVITY
Nickel CVD Coated Nonwovens (NiShield) from Conductive Composites
• Ultra lightweight, conductive, and highly effective broadband shielding.
• Ductile, uniform coatings with excellent thickness control.
• Highest specific shielding performance of any composite solution.
• No change in conductivity when infused or cured.
• Manufactured in a continuous process. • CVD coating is uninterrupted and uniform
over every surface, including binders. • Can be combined in multiple layers. • Engineered conductivity with little
dependence on caliper. • Coating substrates include carbon fiber,
aramid, and carbon nanomaterials. • Continuously coated nonwovens can be wet
processed (binder is protected) • Corrosion resistance and magnetic properties. • Cost savings and performance benefits.
