Open the CIPO recordAbstract From the Canadian patent
A cast tape or medical bandaging product (10) formed from a resin-coated or impregnated fabric material that includes a knitted substrate (16) 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.
