The Planetary Roller Extruder - an Universal Genius
More than 60 years ago, Mr. Wittrock of Messrs. Chemische Werke Hüls AG, nowadays Evonik, has invented the planetary roller extruder which found initially application in the PVC-calender industry. Since the Eighties ENTEX has consequently developed and perfected this process. By initiation of the heat transfer by means of pressurized water and an ameliorated construction of the cooling channels enabling a product-close temperature guidance and therefore having decisively influenced the heat transfer, this system has also been accepted more and more in other fields of application.
Today, the planetary roller extruder is not longer only the classic compounding aggregate for the PVC industry, but covers the whole bandwidth of the compounding and reaction technology.
