Medical rubber and plastic sealing products play a crucial role!

Medical rubber and plastic sealing products refer to sealing components made of rubber or plastic materials used in the medical field. They play a crucial role in ensuring the normal operation of medical equipment, guaranteeing the quality of drugs and patient safety. Here is a detailed introduction about it:

Material characteristics

Silicone rubber: It features outstanding chemical stability, biocompatibility, and excellent resistance to high and low temperatures. It can maintain stable physical properties under high-pressure steam sterilization at 121℃ without deformation, aging, or the release of harmful substances. It is one of the preferred materials for medical rubber and plastic sealing products.

Fluororubber: Renowned for its excellent chemical resistance, for some highly corrosive drug preparations, such as certain chemotherapy drugs, fluororubber sealing rings can effectively resist the erosion of drugs and ensure the durability of sealing performance.

Hydrogenated nitrile butadiene rubber: It has excellent oil resistance and mechanical properties and is widely used in the production equipment of oily drugs or pharmaceuticals containing organic solvents.

Performance requirements

Biocompatibility: It must comply with strict biocompatibility standards, such as ISO 10993 and USP Class VI requirements, to ensure that it will not have adverse effects on human tissues, blood, etc., and will not cause allergies, toxicity or other biological reactions.

Sealing performance: It features extremely high sealing performance, capable of preventing the leakage of gases and liquids, as well as the invasion of microorganisms and particles, ensuring the normal operation of medical equipment and the quality and safety of drugs.

Sterilization resistance: It can withstand various sterilization methods, such as high-pressure steam sterilization, gamma-ray sterilization, ethylene oxide sterilization, etc., and its performance will not change during the sterilization process.

Application field

Medical equipment: Widely used in surgical instruments, syringes, infusion sets, ventilators, oxygen cylinders, gas pipelines, medical imaging equipment, etc. For instance, the interface seals of infusion sets and the piston seals of ventilators, etc., all need to have reliable sealing performance to ensure the safety and effectiveness of medical processes.

Pharmaceutical packaging: such as the rubber stoppers of ampoules and vials, the interface sealing rings of infusion bags, etc., which come into direct contact with the drugs, their sealing performance directly affects the shelf life and quality of the drugs, and can effectively prevent drug leakage, oxidation and microbial contamination.

Implantable devices: Some rubber and plastic sealing products can also be used in implantable devices, such as pacemakers and implantable drug delivery devices, which have extremely high requirements for the biocompatibility and long-term stability of the materials.
