摘要: The present invention relates to a non-hydrated bentonite intimately contacted with polypropene, polybutene, or mixtures thereof provide formable and shapable non-aqueous composition particularly useful as water barrier. can be extruded in the form of rope, rod, sheet like is sufficiently tacky for adherence wall conduit, floor roof areas potential flow prevent seepage through composition. In one embodiment, includes polypropene polybutene an elastomer, such butyl rubber, having sufficient resilience stretch expand expanding upon hydration aid maintaining structural integrity cohesiveness another comprises bentonite, any plasticizer compatible elastomer.
