Abstract
Crystalline polymers having a relatively high melt index and low structured carbon black together produce positive temperature coefficient material which can attain suitable volume resistivity with a greatly reduced annealing time. Temperature self-regulating resistive heating elements may be made with the material in a continuous process where annealing is conducted in a heated zone while the extruded element is in motion or during a short interval when its motion is interrupted.
