SynWrap – Wrapping Tapes Polyglas tape SV3

Polyglas tapes are winding tapes made of unidirectional glass fibers impregnated with a thermosetting polyester resin in B-stage.

Polyglas tapes have a high tensile strength combined with a low elongation and high moisture resistance after curing. The resin system shows sufficient flow during the curing process to create a compact and durable winding or bandage.
