ABSTRACT:
Elastomer compositions are provided for use in preparing objects such as stoppers and pistons for use, for example, in such items as evacuated tubes or syringes for a variety of medical applications. The compositions of the invention are particularly appropriate for producing objects capable of withstanding, simultaneously, the effects of autoclaving temperatures and creep, related to the stress placed on the objects related to the positioning of the objects in use.
