Specialty chemicals company Evonik has begun work to expand its POLYVEST® HT plant in Marl, Germany. The coating and adhesive resins business line expects the additional production capacity for its hydroxyl-terminated polybutadienes (HTPB) – marketed under the brand name POLYVEST® – to be ready as early as the second quarter of 2024 following the double-digit million-euro investment.

“By expanding our operations, we will continue to provide reliable service to our global customers,” says Dr. Stefan Pfaffenbach, head of the business line. “In a highly competitive market, we are strengthening our position as a cost and innovation leader.”

The expansion comes 10 years after the start of production at the HTPB plant in Marl.
