Abstract

En un método para el espumaje de materias plásticas bajo el uso de dioxido de carbono como agente de espumaje, se somete el dioxido de carbono líquido osobrecrítico a una presion elevada y se suministra dioxido de carbono líquido o sobrecrítico a lamateria plástica para espumar la materia plástica. En unadisposicion de espumaje de materia plástica con el uso de dioxido de carbono, una fuente para dioxido de carbono líquido o sobrecrítico está en conexion conpor lo menos un dispositivo para ela umento de la presion del dioxido de carbono que está en conexion con un dispositivo para el espumaje de la materiaplástica.In a method for foaming plastic materials under the use of carbon dioxide as a foaming agent, the osteocritical liquid carbon dioxide is subjected to a high pressure and liquid or supercritical carbon dioxide is supplied to the plastic material to foam the plastic material . In an arrangement of foaming of plastic material with the use of carbon dioxide, a source for liquid or overcritical carbon dioxide is in connection with at least one device for increasing the pressure of the carbon dioxide which is in connection with a device for Foaming of plastic material.
