A tow is an untwisted bundle of continuous filaments. The standard extruded Thunderon® Tow is an acrylic based host fiber, bonded together with an outer conductive layer of copper that surrounds the host fiber. The copper forms a bond with the acrylic host fiber, and unlike metal plated or carbon compound fibers, the fibers do not flake off.
Thunderon® Tow offers much better abrasion resistance and it does not break easily like fine diameter stainless steel fiber. Thunderon® Tow is triangular shaped, which further enhances its conductivity.
