PTC CONDUCTIVE COMPOSITION CONTAINING A LOW MOLECULAR WEIGHT POLYETHYLENE PROCESSING AID

摘要

The invention provided polymeric PTC compositions and electrical PTC devices with higher voltage capability and improved electrical stability. The PTC compositions of the present invention exhibit improved processability and include at a minimum an organic polymer, a conductive filler and a low molecular weight polyethylene processing aid. Depending on device design, the composition can be used in low to high voltage applications.
