BONDING SHEET MATERIAL FOR WEATHER STRIP, WEATHER STRIP, AND METHOD FOR PRODUCING SAME

A bonding sheet material for a weather strip disclosed herein is a composition including at least EPDM, a cross-linking agent, and carbon black, and has a volume resistivity of 1.0 × 10 Ω·cm or more based on a double ring electrode method of JIS-K6271-1: 2015 where a test piece has a thickness of 2 mm. When the composition is placed in a mold and molded to press the composition at 50° C. under 100 Kgf/cm for 60 seconds whereby a molded article is produced, the molded article has a thickness change rate of 100% or less, the thickness change rate being represented by formula (1): Thickness change rate = ((thickness of molded article after 30 minutes from releasing press - thickness of mold)/thickness of mold) × 100.
