PTC conductive polymer compositions |
摘要 |
The invention provides polymeric PTC compositions and electrical PTC devices with higher voltage capability and improved electrical stability. The PTC compositions include at a minimum an organic polymer and a conductive filler including carbon black having an iodine adsorption of less than about 60 mg/g carbon and a dibutyl phthalate absorption of greater than about 115 cc/100 g. Depending on device design, the composition can be used in low to high voltage applications.
