Electrical device comprising a conductive polymer composition |
摘要 |
A conductive polymer composition which has a resistivity of less than 10 ohm-cm and which exhibits PTC behavior comprises a polymeric component and a particulate conductive filler. The polymeric component comprises a first crystalline fluorinated polymer having a first melting point Tm1 and a second crystalline fluorinated polymer having a second melting point Tm2 which is from (Tm1+25) DEG C. to (Tm1+100) DEG C. The composition exhibits one of a number of characteristics, including a relatively high PTC anomaly. The composition is useful in circuit protection devices to be used at high ambient conditions.
