Abstract
An article is formed in a mold having a mold cavity, has a periphery, and defines a score line having a tensile heal strength of less than 200 ppi along the score line. The article includes a cured urethane composition including the reaction product of an isocyanate component and a resin composition. The cured urethane composition is used in a method of forming the article. The method includes the steps of determining a theoretical tensile heal strength along the score line and applying the isocyanate component into the mold cavity in response to the determining of the theoretical tensile heal strength. The method also includes the steps of applying the resin composition into the mold cavity, reacting the isocyanate component and the resin composition to form a urethane composition, curing the urethane composition, and de-molding the article from the mold cavity.
