Abstract:
A co-continuous mouldable polymeric composite with PTC effect has a matrix that comprises at least two immiscible polymers (HDPE, POM), and an electrically conductive filler (CB) in the matrix. At least one of said immiscible polymers is high-density polyethylene (HDPE), and at least one other of said immiscible polymers is polyoxymethylene (POM).
