Provided is a resin composition having excellent flexibility, water vapor barrier properties, and heat resistance. The present invention is a resin composition containing an elastomer having a polyisobutylene skeleton and a silane-modified resin, the resin composition being characterized in that the content of the elastomer having the polyisobutylene skeleton is 30-90% by mass (inclusive) based on the mass of the resin composition; the content of the silane-modified resin is from 10% by mass to 70% by mass (inclusive) based on the mass of the resin composition, the water vapor permeability of the resin composition is 2.0 g * mm/(m < 2 > * 24 h) or less, and TB100/TB25, which is the ratio of the breaking strength TB100 at 100 DEG C to the breaking strength TB25 at 25 DEG C of the resin composition, is from 0.2 to 1.0 (inclusive).
本发明提供一种柔软性、水蒸气阻隔性及耐热性优异的树脂组合物。本发明是含有具有聚异丁烯骨架弹性体和硅烷改性树脂的树脂组合物,其特征在于,具有聚异丁烯骨架的弹性体的含量以树脂组合物的质量为基准是30质量%以上且90质量%以下,硅烷改性树脂的含量以树脂组合物的质量为基准是10质量%以上且70质量%以下,树脂组合物的水蒸气透过度为2.0g·mm/(m2·24h)以下,树脂组合物在100℃下的断裂强度TB100和25℃下的断裂强度TB25之比即TB100/TB25为0.2以上且1.0以下。
