The Medical Systems Division (MSD) of Parker Hannifin Corporation has developed a new class of polyisoprene materials that comply with USP <381> guidelines for both Type I and Type II elastomeric closures. These new polyisoprene compounds are well suited for use in medical septa due to resealability and mechanical, physical, and chemical characteristics.
In the past, stringent USP guidelines have made it difficult to use traditional polyisoprene compounds in elastomeric closures used for aqueous preparations. “While traditional compounds can be formulated to meet Type II guidelines for non-aqueous preparations, they do not pass the absorbance requirements during physiochemical testing” says Medical Systems Division Business Development Manager, Tim Kolankowski.
These new polyisoprene compounds provide proper mechanical and physical properties while exhibiting low needle penetration resistance and low potential for fragmenting or coring.
Parker’s Medical Systems Division, part of the Engineered Materials Group, develops and manufactures components, assemblies and finished devices for our manufacturing partners in the Medical, Diagnostic and Pharmaceutical markets that enable better patient outcomes.
