Electronic device using the polymer and a method for controlling a conductive polymer having PTC characteristics, PTC characteristics of the polymer

摘要

And 30 to 40% by weight, and 20 to 40% by weight of low density polyethylene (LDPE), ethylene PTC conductive polymer mixture comprising an organic polymer, high density polyethylene (HDPE) - acrylic acid copolymer (EAA or ethylene) - the polyolefin component in an amount of 10 to 30 wt% vinyl acetate copolymer (EVA), grafted with maleic anhydride, is added in an amount of 20 to 30 wt% low density polyethylene or high density polyethylene an organic polymer which is obtained is, the conductive particles dispersed in 60 to 120 wt% to 100 wt% of the organic polymer, and 0.2 to 100% by weight of the organic polymer for the crosslinking reaction I comprises a peroxide crosslinking agent added at 0.5 wt%. Therefore, by appropriately adjusting the addition amount of the polyethylene grafted with maleic anhydride, it is possible to control the PTC characteristic trip time and the switching temperatures, such as (trip time).
