Covestro now also offers polyether polyols using bio-circular ¹ feedstock. Together with renewable1 toluene diisocyanate (TDI) and climate-neutral ² methylene diphenyl diisocyanate (MDI), the company can supply both key raw material components for the production of polyurethane (PU) foams based on alternative raw materials. Like TDI and MDI, the polyols are produced with the help of the mass balance approach using renewable precursors - from biowaste and residual materials - which are allocated to the products by calculation.

PU rigid foams with MDI provide very efficient thermal insulation in buildings and refrigeration equipment. The soft foams using TDI provide a lot of comfort in mattresses and upholstered furniture, as well as in car seats and shoes. And with these polyols, Covestro is now able to offer selective prepolymers for various adhesive applications. The introduced mass balance approach enables the gradual substitution of fossil-based raw materials by bio-circular alternatives, which further improves the sustainability in these applications.
