HEAT-RETENTION PANEL MADE OF CLOSED-PORE FOAMED EXTRUDED POLYSTYRENE, METHOD AND PRODUCTION LINE TO THIS END Russian patent published in 2016 - IPC B29C47/38

Abstract RU 2575716 C2

FIELD: process engineering.

SUBSTANCE: claimed invention relates to production of polymer panels used for heat retention. Claimed heat-retention panel is made from closed-pore foamed extruded polystyrene. Note here that the panel is made from the pellets of re-pelletised polystyrene from industrial wastes of processing or production, or from primary production, other than the wastes of used products, solid municipal wastes or the like not contaminated by product residues and additional chemical compounds. Note here that re-pelletised polystyrene featured the melt fluidity index of 5-60.

EFFECT: higher efficiency of heat retention.
