Web banding tapes consist of parallel twisted E-glass yarns
preimpregnated with a special thermosetting polyester resin. The
banding tape is pliable and tacky. Its web structure provides easy
unwind without glass strands separation and overlapping. The
product contributes the characteristics of high tensile strength,
high resistance to shocks, high modulus of elasticity, dimensional
stability as well as no magnetically confining and eddy currents
losses, which can be widely used as ideal banding materials for
electrical motors, transformers and lightning arresters.
