BASF announced the transition of its Rheovis® range to bio-based ethyl acrylate (EA) at its Ludwigshafen and Bradford manufacturing sites. The switch results in a biogenic content of up to 35%, traceable via the ASTM D6866-18 standard, and lowers the product carbon footprint (PCF) by as much as 30% compared to fossil-based versions.

The performance, chemical composition and technical specifications of the Rheovis® products remain unchanged.

“This feedstock switch underlines BASF Additives’ commitment to enable formulators to complete their green transition while ensuring supply reliability and efficiency,” said Sylvain Pascal Huguenard, vice president of global business management for additives at BASF. “BASF’s optimized process and Verbund concept are key levers to further reduce our PCF.”

BASF’s newly launched Rheovis® HS 1101 and HS 1153 HASE rheology modifiers were intentionally developed with elevated biogenic content and without biocides. The company also offers its Biomass Balance (BMB) approach to further reduce PCF, applying certified life cycle assessment methodology in line with ISO 14067:2018 and the Together for Sustainability PCF Guideline.

BASF’s broader portfolio of bio-based raw materials enables formulators to increase the biogenic share of their end products and differentiate beyond what is possible with fossil feedstocks.
