Biobased Polyurethane Foams Based on New Polyol Architectures from Microalgae Oil

Biobased Polyurethane from Palm Kernel Oil-Based Polyol

New polyurethane nanocomposites based on soya oil.

New polyurethane (PU) nanocomposites were prepared from a dispersion of 0 - 5% montmorillonite (MMT) clay with isocyanate and soya oil polyol that was synthesized via transesterification of triglycerides to reduce petroleum dependence. FT-IR spectra indicate the presence of hydrogen bonding between nanoclay and the polymer matrix, whereas the exfoliated structure of clay layers was confirmed by...

Characterization of Biobased Polyurethane Foams Employing Lignin Fractionated from Microwave Liquefied Switchgrass

Lignin samples fractionated frommicrowave liquefied switchgrass were applied in the preparation of semirigid polyurethane (PU) foamswithout purification.Theobjective of this studywas to elucidate the influence of lignin in the PUmatrix on themorphological, chemical,mechanical, and thermal properties of the PU foams.The scanning electronmicroscopy (SEM) images revealed that lignin with 5 and 10%...

The Modification of Polyurethane Foams Using New Boroorganic Polyols (II) Polyurethane Foams from Boron-Modified Hydroxypropyl Urea Derivatives

The work focuses on research related to determination of application possibility of new, ecofriendly boroorganic polyols in rigid polyurethane foams production. Polyols were obtained from hydroxypropyl urea derivatives esterified with boric acid and propylene carbonate. The influence of esterification type on properties of polyols and next on polyurethane foams properties was determined. Nitrog...
