Medical stoppers

Medical stoppers are installed on IV bags and resealable pharmaceutical bottles to allow needle access to fluid or medication without residual leakage. Stopper materials should have good coring resistance, such as accommodate needle insertion without generating  rubber material fragments that can contaminate medications.  It must also be resealable, have low levels of extractable impurities and be inert towards sensitive drugs.

Natural rubber has not been used in this application for several years, partly because of potential Type 1 allergic reactions in patients sensitive to its naturally occurring proteins.  Cariflex polyisoprene products are protein-free and provide the coring resistance and resealability needed for effective medical stopper applications. These high-purity polymers also reduce the possibility of drug contamination from the stopper even after aging.
