and process yield. Future processing technology will depend on machines that can efficiently handle large working volumes, are self-cleaning, offer a wide range of residence times, and exhibit excellent mixing and kneading performance during wet, pasty and viscous phases. LIST KneaderReactor Technology The company’s first successes were in simple drying and kneading applications. Subsequently, LIST Kneader Reactor technology showed that it could effectively combine multiple phases and process steps — reaction, crystallization, drying, melting, mixing, kneading and evaporation — in a single machine. It was this thinking that led List to develop the Mixing Kneader Technology, a new generation of processing technology. In 1969, the AP (All Phases) system was developed and was the first twin shaft machine. In 1972, the company reached another milestone with the development of the single-shaft DISCOTHERM-B. Polymer Processing Hall of Fame Though Heinz List died in 1988, he is remembered both as a pioneering engineer — one of only 26 members of the Polymer Processing Hall of Fame at the University of Akron, Ohio, USA — and as a business leader. Under his sons Jörg and Klaus List, the company has thrived and expanded into new industries: polymers, fibers and food. Today LIST is world leader in numerous industries, including TDI, Sugar Replacer, ABS, Fiber Spinning Solutions, SAP (Super Absorbent Polymers), and EPDM. LIST Today Headquartered in Switzerland, and with offices in the US and Singapore, LIST is the worldwide technology leader and forerunner in dry or concentrated processing focusing on processes that operate without the use of solvents.
