产品介绍 Product introduction
Woven Tape Impregnated with Polyester or Epoxy Resin

       Our company specializes in manufacturing of E-glass fiber tape、polyester filament tape、polyester filament and E-glass fiber interlace tape impregnated with polyester resin or epoxy resin.The tapes above mentioned are woven with yarns then impregnated with resins into semi-curing products. They are widely used as banding materials in the fields of transformer、reactor and lightening arrester, becoming good insulating material for manufacturers.
