PROCESS OF MAKING COLORED EXTRUDED ARTICLES

A process of making colored extruded articles wherein each colorant is contained in a separate color concentrate and each color concentrate is fed to an extruder (8) through a separate gravimetric feeder (2, 4, 6) where the color concentrates are melt blended with a thermoplastic polymer prior to ex...

Zusammenfassung:	A process of making colored extruded articles wherein each colorant is contained in a separate color concentrate and each color concentrate is fed to an extruder (8) through a separate gravimetric feeder (2, 4, 6) where the color concentrates are melt blended with a thermoplastic polymer prior to extruding. Ce procédé de fabrication d'articles extrudés colorés, dans lequel chaque colorant est contenu dans un concentré de matière colorante, consiste à fournir chaque concentré dans une extrudeuse (8), au moyen d'un dispositif d'alimentation (2, 4, 6) gravimétrique séparé, et à mélanger à chaud, dans l'extrudeuse, les concentrés de matière colorante et un polymère thermoplastique, avant extrusion.
