A new component for insulation systems

While the electrical insulation industry has been fortunate in the number and quality of new material developments over the past several decades, (epoxies, silicones and polyimides to name a few) most material and product improvements have been a series of minor changes. One of the more recent steps in this evolution has been the development and commercial adoption of “GEMAT,”* a composite of a bonded and relatively thin glass mat with reinforcement of glass yarns, cloth or organic film. The glass mat alone is of limited value, but can be readily incorporated into a wide variety of composite structures used in the electrical industry.
