Cured rubber components for use with pharmaceutical devices

摘要

Pharmaceutical containers containing at least one shaped component serving as a sealing barrier such as closure, stopper or plunger, for the contents of the container are disclosed. Such sealing barriers are made from elastomeric compositions containing a silylated copolymer of isobutylene/isoprene (butyl rubber) and para-methylstyrene which are curable by contact with moisture.
