Palsgaard (Juelsminde, Denmark) has announced the introduction of an efficient new plant-based, food-grade anti-fouling additive for the polypropylene and polyethylene polymerisation process.
The new product, Einar® 981, has been developed to remove severe concerns about the ethoxylated amine chemistry currently used.
Einar 981 is supplied as a clear and easily pumpable liquid for use in existing dosing systems. It eliminates static build-up during polymerisation and prevents fouling of the reactor wall, thus helping PP and PE producers maintain the cooling efficiency of the reactor. Building on Palsgaard’s proven chemistry of renewable anti-static polymer additives, it provides high anti-fouling efficiency at low concentration (100–300 ppm) without any negative effects on catalyst mileage, productivity, or final polymer performance.
The active compound of Einar 981 is a polyglycerol ester (PGE) blend of fatty acids derived from RSPO  certified sustainable palm oil. As a non-toxic and food-contact approved anti-fouling additive, the product offers a drop-in regulatory compliant solution to replace incumbent ethoxylated amines and can also be used as a more efficient alternative to sorbitan monooleates. This makes it an ideal process additive in the polymerisation of PP and PE materials for sensitive applications, including e.g. medical devices and baby food containers.
“Polyolefin producers are under growing pressure from converters and brand owners to abandon the use of ethoxylated amines in their polymerisation processes and switch to safer products without any regulatory concerns”, says Ulrik Aunskjær, Global Business Director, Bio Specialty Additives at Palsgaard. “Einar 981 is our answer to meet this challenge with a highly sustainable, renewable and food-grade anti-fouling process aid that demonstrates our expertise in customer and market focused renewable polymer additives”.
Einar 981 is produced in CO2-neutral facilities and will be commercially available worldwide. It will be officially introduced to the market at K 2022 in Düsseldorf, Germany (in Hall 7, Level 1, Booth D20). AT
