TL;DR: In this paper, the influence of the biopolyol content on the chemical and cellular structure, insulation properties, static and dynamic mechanical properties, thermal degradation and fire behavior of rigid polyurethane-polyisocyanurate foams was investigated.

TL;DR: The use of glycerol in polymer technology and the attempts of crude Glycerol incorporation into this field reported in literature are summarized.

TL;DR: Interestingly, all 3D printed samples showed surprisingly high values of impact strength considering their calculated brittleness, which provides new insights into understanding the mechanical performance of3D printed structures.

TL;DR: In this paper, lignocellulose biomass liquefaction was used to produce biopolyols suitable for the manufacturing of rigid polyurethane foams, and the results of rheological tests, analyzed with the use of Ostwald-de Waele and Herschel Bulkley models, revealed that the prepared polyols can be classified as pseudoplastic fluids with viscosity values similar to those of commercially available products.

TL;DR: In this paper, a flexible medical-grade filament for FDM/FFF 3DP -Bioflex® (Filoalfa) was evaluated using a series of in vitro studies to assess its potential as as implantable structures.
