Thermally & electrically conductive materials
High-purity materials from a leader in electrically and thermally conductive silicones
With a heritage that spans more than 40 years, NuSil® conductive materials from Avantor® have been critical to the success of the most demanding applications. Manufacturers from leading space, aviation and defense programs, as well as the optoelectronics and electronics industries, rely on our highly purified silicones and customization capabilities to find the right solution for their diverse needs.
Our expertise in silicones allows us to develop a wide range of conductive materials, from adhesives to encapsulants that spread easily and conform to complex geometries to ensure good contact.
- Thermally conductive silicones: Our products safely transfer heat without adding stress to the systems and can also be formulated to be electrically insulating. Unlike thermal pads, NuSil thermally conductive silicone adhesives and encapsulants can be applied with thin bond lines for lower thermal resistance.
- Electrically conductive silicones: These silicones enable static to dissipate continuously rather than accumulate and discharge rapidly, which can damage sensitive electronic components. The electrical conductivity is measured by volume resistivity (Ω·cm) and is used to gauge the EMI shielding effectiveness of the material.
No matter what kind of silicone product you are formulating, NuSil has the expertise, processes and proprietary technology to customize our silicone polymers and catalysts 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 your process and end application performance requirements.
