Sustaining innovation in processing aids
Manufacturers of processing aids have added sustainability to the list of essential
innovations.Peter Mapleston reports on some of the latest developments
In today’s climate, sustainability is key when it comes to processing aids and lubricants for plastics compounds. These additives have long been used to facilitate compounding and final product processing but now producers are increasingly looking to “green” sourcing and supply chains. Functionality remains important, of course, and suppliers are also paying particular attention to process economics. A prime example of the sutainability trend can be seen at Clariant. At the K show last year it announced that it had teamed up with Neste — the Finnish company that began as an oil producer but is now a leading player in the shift to renewable resources — to offer a wide range of additives based on mass balance-certified ethylene and propylene from renewable hydrocarbons. The renewable hydrocarbons come from raw
materials such as waste and residue oils. Because they are chemically identical to current alternatives, the Clariant Terra additives are like-for-like drop-ins

— there is no need to retest, renew registrations or to modify production processes or equipment. In addition to its Terra range, Clariant has also
introduced the Vita range, nine rice bran wax- based solutions for formulators of high-performing engineering plastics, bioplastic compounds, masterbatches and coatings, based on non-food competing feedstock. Frank Neuber is North America Technical Man- ager in the Advanced Surface Solutions section of Clariant’s Additives Business Unit. He sees sustain- ability as one of the main influences driving new developments in processing aids and lubricants. “Sustainability has become one of the main
topics of interest for most of our clients. Many major clients have even created new positions for Managers of Sustainability, usually with a VP or Director title. Clariant’s non-food-competing and sustainable products, such as Licocene Terra and Licocare RBW Vita, have been met with enthusiasm by these companies,” he says.
