|Kraton Performance Polymers Reveals Medical Stopper Study Results|
The paper, "Improved Medical Stopper Solutions with High Performance, Anionic Isoprene Rubber," compares the chemistry and performance of four rubber families that are currently used in medical stoppers: anionic polyisoprene (IR); Ziegler-Natta IR; chlorobutyl rubber; and bromobutyl rubber. The study was performed by a third party using regular medical stopper test protocols. It showed that medical stoppers made with Cariflex™ polyisoprene products, an anionic IR made by
"The results of the study will demonstrate that anionic isoprene rubber delivers a unique combination of advantages including the absence of natural rubber proteins present in NR, an odor-free formulation with very low residual metals and no residual catalysts, low needle insertion force, and minimal risk of rubber fragmentation (coring) and medication contamination due to needle insertion," said Dr.
Dr. Henderson's presentation is scheduled at
Cariflex polyisoprene products are the ideal alternative to natural rubber for applications that demand extreme purity, exceptional protection and consistently high quality. Cariflex products offer a pure and versatile option for manufacturing applications that require the high tensile strength and tear resistance of natural rubber without the impurities that cause discoloration, odor and allergic reactions.
