The rubber stopper protects the medicine from environmental influences and
helps maintain the quality and safety of the medicine.
There are various elastomer formulations for stoppers. Natural rubber is a
general-purpose elastomer, mainly used for water-based liquid filling products
in the pH range of 4.0-7.5. Its resealability is an advantage in multi-dose
applications. The formula uses dry natural rubber and no liquid latex. The
post-treatment cycle (PEP 1) reduces the content of volatile extractables in
the rubber component. The extractable formula of butyl stopper is very low and
can be used with liquid, lyophilized or dry powder products that need to
prevent oxygen or moisture penetration. The stopper coated with PTFE provides
an inert barrier to minimize the interaction between the reagent and the
container.
