Unidirectional bundling tape of fiberglass impregnated resin for electrical purpose (Hereinafter abbr. as unidirectional bundling tape)
It is a kind of B-stage tape material with certain width, which is manufactured by continous non-alkali fiberglass arranged in one-way line (twisted or untwisted) being treated and impregnated in thermosetting resin. It is used for bundling materials of motors, appliance, and electrical equipments.
Fiberglass unidirectional bundling tape with high intensity
It is a fiberglass unidirectional bundling tape made from twisted or untwisted fiberglass yarn with high intensity as basal material.
Web unidirectional bundling tape
It is an unidirectional bundling tape which presents web shape when being pulled crosswise.
