Solid state microcellular foaming method including continuous saturation of solid polymeric material

A method for saturating a thermoplastic polymer material includes continuously moving the polymer material through a pressurized pressure vessel. To do this, the method includes sealing the pressure vessel with a series of dynamic seals that allows the polymer material to continuously move through t...

Beschreibung
Zusammenfassung:	A method for saturating a thermoplastic polymer material includes continuously moving the polymer material through a pressurized pressure vessel. To do this, the method includes sealing the pressure vessel with a series of dynamic seals that allows the polymer material to continuously move through the pressure vessel while maintaining the pressure inside the pressure vessel.
