GIESSBARE POLYURETHAN-ELASTOMERE FÜR INDUSTRIELLE WALZEN |
摘要 |
The present invention relates to polyurethane elastomer systems for industrial and paper mill rolls and more particularly to polyurethane covered rolls made from a new polyurethane composition of a polyurethane prepolymer cured with an aromatic diamine and a hydroxyl-terminated polybutadiene resin. Rolls made with this new polyurethane composition exhibit improved dynamics, hydrolytic stability, and reduced water vapor transmission over conventional polyurethane elastomer systems. |
