Palsgaard A/S has introduced Einar 987, a non-toxic, food-grade anti-fouling additive for polypropylene and polyethylene polymerisation. The product is positioned as a safer and more sustainable alternative to ethoxylated amine (EA) chemistry currently used by polyolefin producers. Supplied as a clear, viscous liquid, the active compound is a polyglycerol ester blend of fatty acids derived from vegetable oils. According to the company, Einar 987 is food-contact approved and intended as a regulatory-compliant, drop-in replacement for incumbent EA-based solutions.
In operation, the additive addresses reactor fouling by mitigating powder adhesion to the reactor wall, thereby supporting stable reaction temperatures and process consistency. Palsgaard states that the material’s anti-static properties play a key role in maintaining production performance and consistent product quality. Laura Juhl, Application Manager for Palsgaard’s Bio-Speciality Additives, said: "Polyolefin resin producers stand to benefit directly from this technology, as its anti-static properties help to ensure the polymer powder does not cling to the reactor wall during polymerisation. This serves to stabilise the reaction temperature, sustain a high production performance and enable consistent product quality."
Safety concerns over amine chemistry have led many resin makers to evaluate alternatives. Einar 987 is reported to be effective at low dosages of 100-300 ppm and to support long catalyst mileage without compromising performance. The formulation was developed drawing on the company’s experience with anti-static and food-safe chemistries, with the stated goal of matching or exceeding the performance of conventional EA-based options while improving the safety profile.
Palsgaard notes that several trials with resin producers have been completed successfully. The company’s technical team is available to support additional evaluations to facilitate adoption and process integration where required.
Composition and function
Einar 987’s active phase is a blend of polyglycerol esters of fatty acids from vegetable oils, designed to deliver anti-fouling performance during PE and PP polymerisation. Delivered as a clear, viscous liquid, it is intended to replace EA additives in existing dosing setups as a drop-in solution. The product’s anti-static behavior is intended to reduce powder build-up on reactor surfaces, which can otherwise disrupt heat transfer and production stability.

Presentation at K 2025
Palsgaard plans to showcase Einar 987 alongside other plant-based polymer additives at K 2025 in Dusseldorf, Germany. The company will exhibit in Hall 7, Level 1, Booth C15, from October 8 to 15.
