Medical-grade silicones for pharmaceutical manufacturing

The application flexibility of silicones and their compatibility with sterilization techniques makes them ideal for tubing and assemblies used for manufacture of pharmaceuticals and biologics.

Advances in medical-grade silicones for pharmaceutical manufacturing

Over the years silicones elastomers have become the go to choice for replacing stainless steel in flexible assemblies for pharmaceutical manufacturing.  By replacing stainless steel or other rigid materials pharmaceutical manufacturers no longer have costly cleanouts between runs when changing over to a new product or new lot material. Silicones allow these assemblies to be disposable, greatly reducing the chance for cross contamination which can be very costly in terms of product disposal or even potentially recalls.   

Using high performance medical grade silicones offer several key advantages when extruded in to tubing or molded into sampling assemblies:   

  • High physical properties in terms of elongation and tensile make it outperform many competitive materials.  
  • Thermal stability -Silicone tubing and assemblies can operate with little impact on performance anywhere from -80 °C to +215 °C
  • High Purity- In pharma manufacturing, one of the most important factors is being certain that materials which come in contact with the actives being produced do not release any extractables or leachables which can contaminate the end drug or biologic
  • Easily Sterilizable - assemblies and tubing can be made packaged then sterilized through methods such as Gamma, Autoclave or ETO with little impact to the polymers performance

While silicones have been used for more than 30 years in fluid transfer, their usage in pharma manufacturing will continue to grow with the ever-changing regulatory environment.  They offer a long history of performance, cost benefit in usage and acquisition as well as a great deal of risk mitigation.
