Compared to competitor materials, biobased KLIMA-PUR frames are positioned as a product with the highest thermal insulation performance. Through BIO4EEB, a new lab-developed formulation with 20-30% biobased raw material and 20-30% of recycled content will be integrated in a pilot-plant production scale, including an improvement in density reduction that will lead to higher thermal insulation to be implemented in real environment after prototypes certification.
Product development
To develop the optimal bio-based polyurethane (bioPUR) foam and window frame, the Design of Experiments (DOE) is structured to optimize key performance metrics, including thermal conductivity, density, fire resistance, and processability.
The five formulations were assessed based on considerations such as polyol compatibility with other biobased polyols, average functionality of the polyol phase, which represents the average number of reactive sites per molecule and influences crosslinking density, viscosity, bio-based content, and ease of processing.
