Abstract:
1. A finger trap safety system comprising a conductive polymer composition comprising at least one polymer and at least one carbon black having an STSA of from about 10 to about 200 m 2 /g, an I 2 No of from about 15 to about 250 mg/g, a tinting strength of about 130% or less, a DBPA of from about 20 to about 450 cc/100 g, a CDBP of from about 20 to about 400 cc/100 g, a ratio of I 2 No to STSA of from about 0.4 to about 2.5, a mean particle size of from about 14 to about 250 nm, and a % volatiles of less than about 1.0%, wherein the carbon black comprises from about 5 to about 40% by weight of the conductive polymer composition, and wherein the conductive polymer composition has a volume resistivity of greater than about 100 ohm-cm at room temperature.
