An adhesive sheet for a weather strip disclosed herein is a composition comprising at least EPDM, a crosslinking agent, and carbon black, and has a volume resistivity of 1.0 * 106 Omega * cm or more based on a JIS-K6271-1: 2015 double ring electrode method of a test strip having a thickness of 2 mm. When the composition is placed in a mold and press-molded at 100 Kgf/cm2 and 50 DEG C for 60 seconds, a molded article is prepared having a rate of change in thickness of 100% or less, the rate of change in thickness being represented by the following formula (1): rate of change in thickness = ((thickness of molded article after release of pressing-mold thickness)/mold thickness) * 100.
一种用于本文公开的挡风雨条的粘合片材为至少包含EPDM、交联剂和炭黑的组合物,并且基于厚度为2mm的测试片的JIS‑K6271‑1:2015的双环电极法,具有1.0×106Ω·cm以上的体积电阻率。当组合物放置在模具中并在100Kgf/cm2且50℃下压制成型组合物60秒,由此制备成型件,该成型件具有100%以下的厚度变化率,厚度变化率由以下式(1)表示:厚度变化率=((解除压制30分钟后成型件的厚度‑模具厚度)/模具厚度)×100。
