Tailoring of insulation and adhesives for superconducting magnets and devices

Polymer-based insulation and adhesives are integral components of superconducting devices. These materials primarily provide mechanical strength and electrical insulation. Specialized formulations and evaluation techniques have been employed to make these materials suitable for the harsh cryogenic environment. Many devices require specialized or unique properties or processing. Composite Technology Development, Inc, (CTD) has developed substantial capability to tailor these products for use at cryogenic temperatures. Tailoring can provide enhanced mechanical and electrical properties. In addition, products can be tailored to provide more cost effective processing. Furthermore, thermal expansion, thermal conductivity, adhesion, and several other properties can also be tailored. Product tailoring techniques, test methods, product performance characteristics and processing parameters are discussed in the context of several case studies.
