Filed:

Nov 16, 2000

Appl. No.:

09/714424

Inventors:

Carl J. Serman - Cranberry Township PA
Kary L Valentine - Mars PA

Assignee:

C. U. E., Inc. - Cranberry Township PA

International Classification:

B29C 4402

US Classification:

264 51, 264 54

Abstract:

The present invention is a high performance microcellular polyurethane foam suitable for numerous applications normally considered outside the realm of conventional solid systems. Also included in the present invention is a method of manufacturing the high performance microcellular polyurethane foam using controlled water addition, foam surfactant addition, a modified catalyst system, the addition of a delayed action tin catalyst and a reduced NCO/OH ratio. The present invention has special application for industrial parts, especially the bowling equipment industry and the cardboard manufacturing industry.

International Classification:

E01F 9/011
E01F 13/02

US Classification:

404 6, 404 9, 404 10

Abstract:

An impact attenuator system includes a hyperelastic member that comprises an energy absorbing material which behaves in a rate-independent hyperelastic manner so that its permanent set is minimized and the material can absorb tremendous amounts of impact energy while remaining fully recoverable.

International Classification:

C08G 1824

US Classification:

528 58

Abstract:

This invention relates to novel light stable elastomers which exhibit good dynamic properties, and a process for their preparation. These elastomers comprise the reaction product of an isocyanate propolymer, a chain extender, and a catalyst selected from i) solid delayed action catalysts having a melting point of greater than about 60. degree. C. , ii) alkyl substituted organotin catalysts containing alkylmercaptide ligands, and which are liquid at room temperature, and iii) alkyl substituted organotin catalysts containing sulfur bridging groups, and which are liquid at room temperature.
