Electrical insulation aramid board produced by Hanyao factory is available in low, medium, and high density grades. Made from 100% aramid fiber, it offers excellent heat resistance, chemical stability, electrical and mechanical strength, and good saturation resistance. It combines rigidity with processability, and performs well in both air and oil. Typical applications include molded parts such as V-rings, angle rings, and peripheral insulation for transformers, gap spacers, and rolled sleeves.
