0.3mm Epoxy Resin Impregnated Unidirectional Fiberglass Banding Tape Impregnated Fiberglass Banding Tape Class F
1. Introduction:
Jiangnan provides an electrical grade, parallel glass banding tape, impregnated with an uncured, high temperature, modified polyester resin. The glass fibers used in this tape are specially treated to improve moisture resistance.
During cure, resin flow fills voids and air spaces, producing a homogeneous laminate with a smooth resin rich surface. The thermosetting modified polyester resin provides excellent arc resistance and minimizes flashover
