VHR-115 is a dense, rigid material produced in multi-ply construction from unbleached kraft pulp and acrylic polymer. VHR-115 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 many coil, transformer, motor, electrical hardware and electronic applications where the need for 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.
