摘要：
A method for producing expanded thermoplastic polymeric (eTP) material and tuning the density of the eTP during the process of producing said eTP wherein the density of the eTP material can be decreased by increasing the partial pressure of the at least one gas which is soluble in the TP material and/or by increasing the total pressure during the charging step.
