Chemical Cleanliness, Dielectric & Chemical Strength

High dielectric strength with low water absorption, Hitex is used in electrical punchout parts, gaskets, transformers, electronic and lighting applications.

Windsor Stevens Hitex is a dense, rigid material produced in multi-ply construction from unbleached Kraft pulp. Hitex has excellent dielectric and mechanical strengths, low water absorption and is free of conducting particles, chemical impurities and foreign matter. Its chemical cleanliness accounts for its excellent aging characteristics.

Hitex can be used in numerous coil, transformer, motor, electrical hardware and electronic applications where excellent dielectric and physical strengths are required. It is not advocated for use with dielectric liquids.

Hitex is available in sheets, strips, mill rolls and slit rolls in thicknesses from .007” to .062”. Above .062” available only in sheets and strips.
