Ravel-Free Orthopaedic Fiberglass Casting Tapes (1)
A ravel-free orthopaedic fiberglass casting tape in which a fiberglass containing substrate is coated with a soft flexible binder to prevent the cut edges of the substrate from raveling. Plaster of paris casts to immobilize body members or limbs after fractures or breaks have been largely supplemented by synthetic casting tapes and bandages which employ polymeric materials in place of plaster of Paris. Polyurethane prepolymers, capable of being cured when reacted with water, have found wide use as replacement for plaster of Paris.
