摘要：
A polymer casting formulation for producing molded polymeric structural members comprises a liquid mixture that contains a polyisocyanate component comprising at least two polyisocyanates; and an isocyanate-reactive component comprising at least two isocyanate-reactive compounds, which formulation cures to form a polyurethane. Methods of using the casting formulation to produce molded polymer structural members and the structural members that are produced by such a method are also described.
