Evonik invests double-digit million euro amount in Marl
Das Spezialchemieunternehmen Evonik beginnt mit dem Ausbau seiner “Polyvest HT”-Anlage in Marl, Deutschland.
The Coating & Adhesive Resins business line expects the additional production capacity for its hydroxyl-terminated polybutadienes (HTPB), which are marketed under the brand name Polyvest, to be available as early as the second quarter of 2024 following the investment in the double-digit million range. The expansion comes ten years after the start of production at the HTPB plant in Marl.
“Dual-use products such as polybutadienes require a high degree of sensitivity and expertise when dealing with customers and authorities,” says Dr. Jürgen Herwig, Head of the Polybutadienes and Specialty Acrylates Product Line. Production is backward-integrated, as butadiene is produced directly at the Marl site and hydrogen peroxide is supplied by the Evonik Group. Evonik thus benefits from the security of supply of raw materials for Polyvest production. In addition, Evonik’s application technology and research and development departments are also located at the Marl site, ensuring a seamless link from development and testing in the laboratory to production.
Polyvest ht is a liquid, hydroxyl-terminated polybutadiene produced by radical polymerization. The polymer has a highly hydrophobic polybutadiene backbone and primary hydroxyl groups that are accessible for precise chemical modification. It is used as a polyol component in various adhesive and sealant applications. Polyvest HT-A is intended for aerospace applications.
