Abstract: A puncture resistant composite article includes a first layer having a specific gravity of from 0.9 to 1.15 g/ml and formed from an elastomeric urethane composition including the cured reaction product of an isocyanate component and a resin composition including polytetrahydrofuran. The composite article also includes a second layer disposed on the first layer. A method of forming the composite article includes the step of spraying the isocyanate component and the particular resin composition into a mold cavity in a conical spray pattern or a substantially planar spray pattern. The method also includes the steps of reacting the isocyanate component and the resin composition to form the elastomeric urethane composition, curing the elastomeric urethane composition to form the first layer, applying a urethane composition into the mold cavity, curing the urethane composition to form the second layer and the composite article, and de-molding the composite article.

Abstract: The subject invention provides a composition and a process for forming a flexible polyurethane foam sealing device having improved compression set properties at increased temperatures. The sealing device is formed without the use of chemical blowing agents. The composition includes an isocyanate component for reaction with a resin component comprising an isocyanate-reactive component having a functionality of least four and a hydroxyl number of less than 40, a graft dispersion, and a physical blowing agent. The most preferred physical blowing agent is HFC-245 fa or 1,1,1,3,3-pentafluoropropane.

Abstract: A steering column assembly includes a steering column having a selectively collapsible structure that enables said column to collapse in the event of an impact force resulting from a vehicle crash. An adaptive energy absorbing device is associated with said column and operates in a first condition to absorb a first level of energy of the collapsing column and in a second condition to absorb a second level of energy of the collapsing column. The assembly includes a telltale detection device that is associated with the adaptive energy absorbing device and is responsive to a change in condition of the energy absorbing device prior to a collapse event to provide a signal to a user of the condition of the energy absorbing device.
