  • Patent number: 10858506
    Abstract: A conductive heating composition includes a polyolefin elastomer, a crystalline non-grafted polyolefin, a crystalline polymer which is grafted or copolymerized with a monomeric unit, and a conductive filler. The composition has a surface resistivity ranging from 1.0E+01 ohm to 1.0E+06 ohm, and a volume resistivity ranging from 8.0E+01 ohm-cm to less than 1.0E+05 ohm-cm. When the composition is heated from 20° C. to 90° C., a log value of a resistance of the composition increases with a slope ranging from 3E?02 log ohm/° C. to 9E?02 log ohm/° C. After a specimen made of the composition is repeatedly bent 300 times, a surface resistance of the specimen at a room temperature increases by a rate of less than 300%.
