Description
Polyglass (esterbant) bandage tape is made of glass fibers pre-impregnated with a special thermosetting resin based on PEI – polyesterimide. Also called non-woven glass tape, it has excellent thermal insulation properties compared to other types of bandage tapes and has thermal insulation class F (155° C) or class H (180° C). The glass banding tape features resistance to high temperatures and high humidity. Polyglas tape is easy to process and apply, which saves labor and effort and speeds up the production process. The advantage of polyglass banding tape over the woven fiberglass banding tape is in the strength it gains after baking and the adhesion it obtains, making the construction more durable.
