Title (EN) METHOD FOR PREPARING BEADS BASED ON EXPANDED POLYMER
(FR) PROCEDE DE PREPARATION DE PERLE A BASE DE POLYMERE EXPANSE
Abstract: front page image
(EN)The invention relates to a method for preparing beads from expanded polymer, with a continuous kin, comprising the following method steps: extrusion of an expanding composition, comprising a thermoplastic polymer and a blowing agent through a die in the molten state, to give the expansion and cooling and cutting the obtained expanded material at the outlet from the die by means of a knife.
(FR)Procédé de préparation d’une perle à base de polymère expansé et à peau continue comprenant les étapes successives suivantes : extruder à travers une filière une composition expansible comprenant un polymère thermoplastique et un agent d’expansion, à l’état fondu, pour réaliser l’expansion et refroidir et couper le matériau expansé obtenu en sortie de filière à l’aide d’un couteau.
