UltraSoft™ Knit
UltraSoft™ Knit EMI gasket materials consist of a metallized nylon yarn knit over a flame retardant UL 94 HF-1 low density foam polyester core material. The close-knit stitch of the metallized nylon provides a highly effective EMI shield, as well as a smooth, soft surface that will not abrade plated plastic surfaces.
