Improved Polyurethane-coated Orthopedic Casting Bandage for Medical Application

摘要

A new improved polyester casting bandage, which comprises a knitted polyester substrate coated with polyurethane prepolymer, was developed. The appropriate polyester knitted substrate was selected firstly; the optimal ingredient for the synthesis of coating resin (polyurethane prepolymer) was determined then through a series of trial experiments and factorial experiments; the properties of bandage were checked at last. The results of the experiment indicate that most of the properties of the new product could exceed or approximate to the level of similar product of other countries.
