  • Fiber reinforced TPU composites
    Patent number: 9068076
    Abstract: A catalyst masterbatch is disclosed, which when used with a rigid TPU polymer, will cause the rigid TPU to depolymerize during melt processing and repolymerize as the melt is being cooled. This feature is of particular interest in a pultrusion process to create TPU/fiber composites. The catalyst masterbatch contains a relative soft TPU polymer where the catalyst has been swelled or absorbed into the soft TPU polymer. A carrier, such as a plasticizer, can be used to aid the transport of the catalyst into the soft TPU polymer. The catalyst masterbatch is used as an additive to the rigid TPU in a pultrusion process to make the composites. The catalyst masterbatch can also be used in non-fiber reinforced rigid TPU compositions to increase the Mw of melt processed rigid TPU.
