Low Coring Infusion Rubber Stopper

When evaluating rubber stoppers for infusion bottles, one of the most practical concerns for medical staff is how the material behaves during spike insertion. In a clinical setting, nurses use standard plastic IV spikes to pierce the rubber closure to administer fluids. If the rubber formulation is not balanced correctly, the mechanical action of the spike can shear off tiny pieces of the stopper. This issue, generally known as coring or fragmentation, creates unwanted particulate matter that could potentially enter the fluid pathway.

We approach this specific challenge by closely managing the elasticity and shore hardness of our halogenated butyl rubber. The goal is to provide a material that parts cleanly when pierced by a standard clinical spike, rather than tearing or crumbling. Our stoppers are formulated to offer a predictable puncture profile, minimizing the generation of rubber debris during routine hospital procedures.

By maintaining strict control over the vulcanization process, we ensure the physical integrity of the rubber remains stable. This means the stopper provides enough resistance to maintain a good seal, but yields appropriately when the spike is introduced. For pharmaceutical companies looking to reduce particulate complaints from hospitals, paying attention to the mechanical puncture properties of the rubber stopper is a very standard and effective preventative measure. This component is designed to handle those routine clinical requirements reliably.
