General Description
VHR-115 is a dense, rigid material produced in multi-ply construction from unbleached kraft pulp and acrylic polymer. It 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 in air up to 115°C.
VHR-115 can be used in numerous coil, transformer, motor, electrical hardware and electronic applications where excellent dielectric and physical strengths are required.
VHR-115 is approved by Underwriters Laboratories reference E-31556(M) electrical use at 115°C and mechanical at 110°C.
VHR-115 is available in sheets, strips, mill rolls and slit rolls in thicknesses from .010” to .062”.
