Properties of a new, fire-retardant, thermally-stable, electrical grade resin

During the past few years, considerable effort has been given to the development of heat-resistant thermosetting resins for electrical applications.* Two base resins are now commercially available with some choice of monomer components, depending on the end-use application. Resin 7000* is recommended for long-term performance at temperatures up to and including 220 °C, while 7001,* a lower cost resin, is suggested for temperatures through 200 °C. Both resins can withstand short exposures at considerably higher temperatures. Properties of clear castings and filled mat laminates are excellent. Both mechanical and electrical properties are maintained during thermal aging.
