Silicone Medical Gaskets Used in a Wide Variety of Applications


The medical industry has an ongoing need for silicone medical gaskets that can be used in everything from basic equipment to devices that can be implanted directly into a patient. Given that wide variety of needs, today’s silicone gasket manufacturers offer many materials that can adapt to the specific environment of the gasket. Here are just a few reasons that silicone gasket materials are commonly used in the medical device and healthcare products market:

  • Why choose silicone for medical device gaskets? Compression molded silicone gaskets offer the characteristics that are needed for medical devices. One of the benefits of using silicone is that it offers a high level of flexing that is regularly required of the internal mechanics of a medical device. Additionally, silicone is an inert material and offers a great deal of durability.  This is ideal for medical devices and equipment that will be in use for a long period of time, protecting devices that see heavy use as well as those that are implanted directly into a patient, such as central venous catheters and pacemakers.
  • Diagnostic devices need specialized silicone gasket technology during heavy use periods. To prevent damage during daily use, medical diagnostic devices such as automated blood pressure cuffs, intravenous pumps and temperature gauges benefit from fabricated solid gaskets made from liquid silicone. These can prevent issues with displays and the accumulation of dust which can cause malfunctions while in use. Cushioning pads and silicone foam gaskets can also be made from the same silicone materials, providing a long life to medical device investments.  Liquid silicone can be sprayed right onto a surface during manufacturing instead of creating a separate gasket.  This allows for a higher level of sealing and a decreased chance the gasket will slip during use.
  • Silicone provides protection from EMI fields. In so many medical applications, gaskets need to provide EMI shielding to protect electric emissions from devices and issues with other mechanical units in the medical environment. EMI fields can interfere with diagnostic and testing equipment.  Using silicone can decrease the chances that there will be a malfunction. Carbon-filled silicone rubber can offer grounding for ESD applications. Neoprene gaskets and pads are also useful for this medical application.
  • Gaskets can be created to meet a wide variety of needs. Silicone medical gaskets can be made from compression molded silicone, injection molded liquid silicone rubber, solid silicone, silicone plenum, and semi-conductive carbon-filled silicone rubber gaskets and pads. The versatility of silicone products means that there is a silicone solution for most applications in the healthcare and medical device fields.
