Patent ID: 8168298

Claim:
A method of forming an article having a periphery and defining a score line within the periphery dividing the article into at least a first portion and a second portion separable from the first portion under application of pressure, said method comprising the steps of: a) applying an isocyanate component and a resin composition into a mold cavity, wherein the resin composition comprises a polyol, wherein the polyol comprises an ethylene oxide cap of from 10 to 20 percent by weight based on the total weight of the polyol; b) reacting the isocyanate component and the resin composition to form a urethane composition; c) curing the urethane composition to form a cured urethane composition, wherein the cured urethane composition is elastomeric; d) de-molding the article from the mold cavity; and e) scoring the article within the periphery to form the score line having a tensile heal strength of less than 200 pounds per inch along the score line.
