KangdaCast and KangdaCast Poly are for use in orthopedics. KangdaCast consists of a knitted fiberglass fabric and KangdaCast Poly is composed of knitted polyester fabric. Both of them are impregnated with water-activated polyurethane resin. KangdaCast is harder and easier to be cut than KangdaCast Poly. But KangdaCast Poly is lighter than KangdaCast and can be burnt thoroughly to be environment friendly. KangdaCast Poly products have advantages in these characteristics: lightweight, high strength, radiolucence, and porosity comparing with traditional plaster cast. Besides, the dust generated by removing the cast is lower in quantity and larger in particle size than the dust generated upon the removal of a plaster cast. Exposure to moisture or water initiates a chemical reaction that causes the tape to harden.
