They exhibit good handleability and remain flexible in numerous high temperature applications. Electrical Properties: E-glass fiber is an excellent material for electrical insulation. The combination of
properties such as low moisture absorption, high strength, heat resistance and low dielectric constant
makes glass fiber fabrics ideal as reinforcement for printed circuit boards and insulating varnishes.
Thermal Conductivity: A low coefficient of thermal expansion combined with high thermal conductivity
properties makes glass fabric a dimensionally stable material that rapidly dissipates heat as compared
to asbestos and organic fibers. HIGH TEMPERATURE TEXTILES
