Ensinger ESD Materials from San Diego Plastics, Inc.

Hydel® PC-7

Graphitic Fibril™ Nanotubes shown with carbon powder particles.

Magnified 62,500 times.

A polycarbonate based material with a proprietary carbon filler component.  The highly dispersed filler imparts outstanding electrical consistency to minimize any hot spots. The material has the best repeatability and predictability of any commercially available carbon based filler. HYDEL® PC-7 has minimal sloughing as compared to other carbon based fillers. This material also retains much of the physical properties of polycarbonate without the loss of impact and tensile properties that can occur with standard carbon based or fiber fillers.

  • 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.
