Engineering 185°F - 300°F | Polycarbonate


Hydel®PC-7 ESD Polycarbonate is a static dissipative thermoplastic product containing graphic Fibril™ nanotubes. Unlike conventional carbon fibers, this technology allows for good dimensional stability after machining, outstanding toughness, consistent electrical properties, excellent surface quality, and minimal sloughing. Hydel®PC-7 is available in rod, slab, tubular bar, and profiles.

  • 75% less total carbon content than standard carbon filled ESD materials
  • Lower carbon loading means minimal sloughing or crayoning issues; fewer particulates
  • Zero residual charge
  • Nano fibers do not degrade physical properties
  • Lower warpage than other carbon filled materials
  • Superior machined surface finish

HYDEL®PC-7 ESD is especially suited to applications in the defense industry, specifically in the manufacture of ammunition where it is vital that static charges be suppressed. It can also be used in select applications in the aerospace and electronics industry.
