This paper presents a comparative analysis of bio-based polyurethane insulations and
conventional polyurethanes, emphasizing their mechanical properties, thermal and acoustic …

As sucrose is less expensive and more readily available than tannin, sucrose-based foams
were prepared by incorporating furfuryl alcohol (FA) and glyoxal as a crosslinking agent to …

Non-isocyanate polyurethane (NIPU) as a new type of polyurethane material has become a
hot research topic in the polyurethane industry due to its no utilization of toxic isocyanates …

Heat release rate (HRR) is the principal fire characteristic of materials. There are three
known methods for the measurement of HRR (based on oxygen consumption, mass loss …

Water-blown biopolyurethane (bioPUR) foams are flammable and emit toxic gases during
combustion. Herein, a novel approach suggested by the current study is to use different …

Currently, the plastics industry including polyurethanes is based on the use of
petrochemicals. For this reason, scientists are looking for new types of renewable resources …

The use of alternative raw material sources in polyurethane chemistry is necessary given the
limited supply of fossil fuels, their rising prices and the concern for sustainability. The …

The easy flammability of bio-based rigid polyurethane foams (bio-PUFs) continues to pose a
great challenge to the insulation industry. A novel and reactive phosphorous sunflower oil …

Rigid polyurethane foams (RPUFs) are critically challenged by their inherent high
flammability and the generation of toxic smoke. In this study, we synthesized a novel, easily …

A bio-based polyester polyol (BP41) was synthesized through a one-pot esterification and
condensation reaction involving bio-based 1, 2-propanediol, trimethylolpropane, and adipic …
