ABSTRACT:
A cast tape or medical bandaging product formed from a resin-coated or impregnated fabric material that includes a knitted substrate having a combination of non-fiberglass high and low tenacity yarns such as polypropylene, polyester and elastomer. The polypropylene and polyester yarns have a high number of filaments, typically 48 to 90 filaments. This significantly improves the surface area of the fabric, that helps help to hold the curable resin onto the fabric and avoids pooling. This in turn improves lamination layer-to-layer and gives the substrate high strength.
