NuSil

NuSil is a specialty materials company focused on ultra-high-purity silicone and related advanced materials used in healthcare, life sciences, and high-technology applications. The business is best known for medical-grade silicones used in implantable devices, drug-delivery systems, diagnostics, and other regulated healthcare products, as well as high-performance materials for aerospace, defense, and electronics. NuSil was founded as an independent company and later merged into Avantor in 2016, where it continues to operate as the NuSil brand within Avantor's portfolio. Its offerings include off-the-shelf and custom silicone formulations, along with technical support, analytical capabilities, and manufacturing for highly regulated end markets. For a biotech or medtech analyst, NuSil is primarily a commercial biomaterials and enabling-technology supplier rather than a therapeutics developer.
