0.3mm Thickness Insulation Binding Tape Polyester Resin Impregnated Fiberglass Web Banding Tape
1. Introduction:
Polyglass banding tapes consists of high-strength glass yarns laid parallel, impregnated with special high-temperature thermosetting polyester resin. During cure, the resin flows and fills the voids and air spaces to produce a homogeneous laminate with a smooth resin surface.

3. Polyester Resin Fiberglass Banding Tape Transportation
Banding tape requires special and rapid transportation arrangements. Mutual consultation is suggested for appropriateness depending on the transit period, available modes, handling, etc. Considering the sensitivity of banding tape, the buyer needs to quickly take delivery of the consignment and store it suitably
4. Storage stability
The banding tape should be stored in a low temperature environment. When using, the tape should be restored to the surrounding environment. Outside the use time, it is best to put it in a plastic cover and seal it to keep it clean and prevent moisture from condensing on the product at low temperatures.
