Engineering Zero-Defect Medical BIIR Gaskets for Metered Dose Inhaler (MDI) Valves
In pulmonary drug delivery systems—such as pressurized Metered Dose Inhalers (pMDIs) for asthma therapy—the elastomeric gasket inside the metering valve is not just a passive seal. It is a critical functional component that directly governs dosing accuracy, aerosol stability, and long-term drug purity.
Formulating elastomer components for active pharmaceutical ingredients (APIs) and harsh propellant/solvent matrices requires stringent material science and ultra-clean manufacturing environments.
Here is how precision-molded Medical Bromobutyl Rubber (BIIR) gaskets meet the critical demands of MDI valve engineering:
Proven Chemical Compatibility: Formulated for zero degradation, swelling, or extraction when in continuous contact with APIs like Salbutamol (Albuterol), along with co-solvents and surfactants such as Ethanol and Oleic Acid.
ISO 10993 & E&L Regulatory Compliance: Fully tested to satisfy ISO 10993 biological evaluation standards. Supported by comprehensive Extractables and Leachables (E&L) profiling to guarantee ultra-low organic and inorganic leachable risk into pulmonary formulations.
ISO Class 7 Cleanroom Manufacturing: Every single BIIR gasket is vulcanized, precision-trimmed, cleaned, and inspected within a certified ISO Class 7 cleanroom environment to eliminate airborne particulate and microbial contamination.
Double-Sealed Protective Packaging: All components are immediately double-bagged and sealed inside the controlled cleanroom prior to shipment, preserving strict particle counts and sterilizable integrity during transport.
At Precision Elastomer Parts, we partner with pharmaceutical manufacturers and OEM device engineers to deliver high-integrity elastomer solutions tailored for complex inhalation, parenteral, and diagnostic applications.
