Process for the production of expanded particles of a polymeric material |
| abstract |
ABSTRACT A process for the production of expanded particles including the steps of: (a) providing unexpanded particles formed of the poly-meric material; (b) contacting a nitrogen-containing inorganic gas with the unexpanded particles under a pressurized condition to impregnate the unexpanded particles with said gas, heating the unexpanded particles to a temperature higher than the softening point of the polymeric material and dispersing the unexpanded particles in a liquid dispersing medium, so that a dispersion maintained at a first pressure and containing the softened, gas-impregnated, unexpanded particles is obtained; and (c) subjecting the dispersion to a second pressure lower than said first pressure so that the unexpanded particles are expanded. The expanded particles thus obtained may be suitably used as prefoamed particles for the preparation of foamed articles by molding. |
