Abstract: Reinforced polyurethane/urea elastomers with a specified proportion of urea groups and a specified proportion of urethane groups are produced from an isocyanate-reactive component satisfying specified compositional requirements and an isocyanate-terminated prepolymer produced from specified materials. Two-dimensional polyurethane molded articles produced from these reinforced elastomers are characterized by improved toughness and improved shrinkage characteristics. Such molded articles are particularly useful for making automobile components.

Abstract: Modified polyurethanes based on polyurethane reactive systems composed of at least one organic polyisocyanate and a polyol formulation, which additionally contains at least one polymer modifier and at least one filler are prepared. These modified polyurethanes are useful in the production of electroplated/metallized molded articles.

Abstract: A process for preparing oil and petroleum-resistant cellular to solid (polyurea)polyurethanes (PURS) with improved physical properties in which a polyether polyol component having a number average molecular weight of from 1000 to 8000 and a polyester polyol component having a number average molecular weight of from 1000 to 6000 are reacted with a polyisocyanate and the (polyurea) polyurethanes produced by that process. The (polyurea)polyurethanes are particularly useful for personal safety equipment and in the construction of automobiles.

Abstract: Polyurethane elastomers are produced by reacting a polyether and/or polyester polyol having a starter functionality of at least 2 with an NCO-terminated prepolymer produced with a polyether and/or polyester polyol having a starter functionality of at least 4. These polyurethane elastomers exhibit improved processing characteristics combined with a high heat distortion temperature.

Abstract: Safety clothing is produced by molding polyether-based plastic-forming compositions. Particularly preferred articles of safety clothing produced by this process are safety shoe soles.
