Bio-based rigid polyurethane (BRPU) foams were successfully produced using hydrolytically
depolymerized Kraft lignin (DKL, with M w∼ 1700 g/mole, aliphatic hydroxyl number: 365 …

Polyurethane (PU) production with the use of vegetable oils is greatly appreciated by
researchers due to their low cost, easy availability, and nontoxic nature. The addition of TiO2 …

This study investigates the incorporation of castor oil–based rigid polyurethane foam with
mineral fillers feldspar or kaolinite clay in order to enhance the mechanical, thermal, and …

Sorbitol arises to be a strong candidate for renewably sourced polyol synthesis. Moreover,
processes for extracting sorbitol directly from cellulosic materials are effective, and materials …

The major drawback in the use of Rigid Polyurethane Foam (RPUF) is its high flammability
which limits is industrial applications. In the presented studies, RPUF was incorporated with …

The present study emphasizes the reinforcement of rigid polyurethane foam (RPUF) by the
