Influence of bio-polyols with different molecular weight on properites of PUR-PIR foams
Open Research Data
open access
This work attempts to validate the possibility of replacing petrochemical polyols with previously synthesized bio-polyols and their impact on the structure and properties of rigid polyurethane-polyisocyanurate (PUR-PIR). The influence of bio-polyols addition on foam properties was investigated by mechanical testing, Fourier transform infrared spectroscopy...

Presented dataset includes the results of FTIR and H NMR spectroscopy of bio-based polyester polyol - poly(propylene succinate) (reference sample for materials obtained during MINIATURA 4 project realization).
Valorization of bio-based polyols synthesized via biomass liquefaction
Open Research Data
open access
As the properties of polyols have a huge impact on the properties of manufactured polyurethanes, this study aims to determine the influence of polyethylene glycols with different molecular masses on the course of the biomass liquefaction process and bio-polyol properties. The obtained polyols were characterized by rheological studies. To confirm the...
