FLEXcon Industrial manufactures electrical insulation laminates used as dielectric barriers in motors, generators, and transformers. In addition to protection from dielectric breakdown, these laminates provide thermal protection in every UL recognized service temperature class. Substrates used include the highest quality papers, non-woven fabrics and dielectric films combined with high performance polymer adhesives and coatings. These laminates can withstand processing by automated equipment and can accept varnishes and resins used to encapsulate devices.

FLEXcon Industrial’s Insulation Laminates can be coupled with our Custom Products to provide unique solutions to demanding applications. See our Custom Products page for more information.

FLEXcon Industrial’s Insulation Laminates are UL 1446 Certified.
