Silicone polymers and catalysts

NuSil® specialty silicone polymers and silicone catalysts for high-purity silicone systems

NuSil’s specialty polymers and catalysts are high-purity components specifically made for creating unique silicone compounds. Our materials can be used for a variety of applications with specialized features, such as fuel resistance, high temperature performance, optical coupling and low volatility. NuSil offers functional silicone polymers for formulating addition cure and condensation cure silicones.

Our line includes:

  • Functional polymers: Our portfolio offers both hydride and vinyl functional polymers. Vinyl functional polymers are available with dimethyl, phenyl and fluoro pendant chemistries and can be customized to meet specific requirements.
  • Catalysts: We also offer platinum catalysts for addition-cure reactions that are compatible in different silicone polymer compositions, such as diphenyl and dimethyl.
  • Inhibitors: Our competitive and fugitive inhibitors control the cure rates for high or low temperature curing systems.

Customization mastered

From prototype scale to mass production, NuSil has the expertise, processes and proprietary technology to customize silicones based on your unique specifications. We leverage our insight into the unique silicone chemistry and material properties to supply both off-the-shelf and custom formulations tailored to meet your process and end application performance requirements.
