Abstract:
      The adsorption properties of isobutylene-isoprene rubber freeze-dried rubber plugs were studied from two aspects of compound formulation and storage humidity. The results showed that the misture content of the rubber plug rapid increased in high humidity storage environment.Among three rubber plugs with different compound formulation，the one with the largest specific surface area had the highest adsorption rate and the weakest water blocking capacity，indicating that the water vapor permeability was high，and should be avoided to use rubber plug with this compound formulation.
