Abstract
The present invention relates to orthopedic casting materials having reduced tack and methods for preparing and using such orthopedic casting materials, wherein the materials comprise a nonwoven, stretchable fabric which is impregnated with a curable prepolymer resin. The nonwoven fabric comprises fiber bundles and apertures between the fiber bundles, with each of the fiber bundles comprising a plurality of fibers having interstices therebetween. The curable prepolymer resin is impregnated into the nonwoven fabric such that the interstices between the fibers receive the resin, while leaving the apertures between fiber bundles substantially unoccluded. Such orthopedic casting materials are relatively inexpensive and exhibit improved properties.
