Lightweight Trevira Jacket, with EMI Shielding and a Hook-and-Loop Closure

Trevira consists of a lightweight (.015"), fire-retardant, woven-fabric jacketing that, if used with the right materials, could create a complete zero-halogen and cadmium-free product.

The hook-and-loop closure is sewn using the double-stich technique that allows installation in many rugged applications.

Because of its versatility, the product offers a multitude of options including EMI shielding, Kevlar thread, or even high-temperature Aramid hook-and-loop. When choosing this version of Hook-N-Shield® (Trevira), the product also includes a ground wire sewn directly into it.
