Extrusion International 5-2025-USA

53 Extrusion International 5/2025 Anti-Fouling Additive for the PE and PP Polymerisation Process Introduced P alsgaard, a leader in plant-based additives for the plastics industry, has introduced a safe, sustainable anti- fouling additive for the polypropylene and polyethylene polymerisation pro- cess. Developed from renewable raw materials, the food-grade additive Einar® 987 has been developed to ad- dress concerns about the ethoxylated amine (EA) chemistry currently used. The active compound of Einar® 987 – which is supplied as a clear, vis- cous liquid – is a polyglycerol ester (PGE) blend of fatty acids from vegeta- ble oils. As a non-toxic and food-con- tact-approved anti-fouling additive, it offers a drop-in, regulatory-compliant solution to replace the incumbent EAs. When developing Einar® 987, Pal- sgaard drew on its extensive knowl- edge of anti-static and food-safe chemistries. The company considered a number of parameters when develop- ing this new formulation, focusing on creating an additive that would offer at least equal performance while also being both safer and more sustainable than currently available options. “Polyole n resin producers stand to bene t directly from this technol - ogy, as its anti-static properties help to ensure the polymer powder does not cling to the reactor wall during polymerisation. This serves to stabi- lise the reaction temperature, sustain a high production performance and enable consistent product quality,” said Laura Juhl, Application Manager for Palsgaard’s Bio-Speciality Addi- tives. Safety concerns over amine chem- istry have led resin makers to seek al- ternatives for some time now. Einar® 987 is effective at low dosages of just 100 to 300 ppm and helps to deliver long catalyst mileage without any compromise in performance. Palsgaard, which has been develop- ing plant-based solutions since 1917, has already conducted several suc- cessful trials of Einar® 987 with resin producers. Additional evaluations can be supported by the company’s tech- nical team to facilitate smooth adop- tion of the new, safer chemistry. Einar® 987 is one of several prod- ucts that Palsgaard will be showcasing on its booth at the upcoming K 2025 trade show in Dusseldorf, Germany.
