Polyglass tapes consist of parallel twisted E-glass yarns preimpregnated with a special thermosetting polyester resin, which is
pliable and tacky. Its web structure provides easy unwind without glass strands separation andoverlapping. The product contributes the characteristics of high tensile strength, highresistance to shocks, high modulus of elasticity, dimensional stability as well as nomagnetically confining and eddy currents losses, which can be widely used as ideal bandingmaterials for electrical motors, transformers and lightning arresters.
