Primer on conductive plastics: Things to consider as you specify these materials

By MPW Staff
Published: November 18th, 2010

Conductive plastics are developed by compounding thermoplastics with electrically conductive materials such as carbon or steel fibers, carbon nanotubes (CNTs) or graphite, and other additives to enhance the dispersion of the conductive materials into the polymeric matrix. The result is to give conductive properties to some plastics that normally are isolators.
