Plant-based additives to enhance PE and PP polymerisation

At the pre-K 2025 conferences organised by EMG on 4-5 June at the Millennium Tower in Rotterdam, Palsgaard presented its latest bio-based solutions for the packaging industry to the international press on 4 June. With a vision that brings together nature, innovation and safety, the Danish multinational is expanding its global presence by offering natural additives aimed at setting a new technological and ethical benchmark for plastic materials.

Among the innovations announced was Einar 987, an additive developed to improve the polymerisation process of PE and PP, while eliminating the need for ethoxylated amines (EA) – substances increasingly scrutinised due to potential health and environmental risks. Derived from vegetable oils and approved for food contact, Einar 987 is a polyglycerol ester (PGE) blend that prevents polymer powder build-up on reactor walls, maintaining consistent temperature and enabling stable, high-performance production.

“This is a safe, sustainable solution that can be immediately implemented in existing systems,” explained Laura Juhl, Application Manager for Bio-Speciality Additives at Palsgaard, during the conference. The product is effective at low concentrations (100-300 ppm) and has already passed both internal and external testing with leading polymer manufacturers, positioning itself as a viable alternative for those seeking high performance without compromising on safety or environmental compatibility.
