Bio-based polyols for polyurethanes: foams, coatings, adhesives
A polyol reacts with an isocyanate to form a polyurethane. When plant-based, it replaces part of the petroleum in the formulation and lowers its carbon footprint, often without changing the process.

Can a bio-based polyol be used as a direct replacement?
Often only in part: you first replace 10 to 30% of the fossil-based polyol, then adjust the formulation. Tell us your hydroxyl value and your application, and we will suggest the closest references.
How is the bio-based content measured?
By carbon-14 analysis, according to the ASTM D6866 or EN 16785 standards: the producer's technical data sheet gives the share of carbon of plant origin.
Tell us the application, the target characteristics and the volume, and we will get back to you with a quotation.
