Polyurethane foams are materials characterized by low density and thermal conductivity and
can therefore be used as thermal insulation materials. They are synthesized from toxic and …

Polyurethane (PU) elastomers represent an important class of segmented copolymers.
Thanks to many available chemical compositions, a rather broad range of chemical …

Thermoplastic polyurethanes (TPUs) are among the most versatile engineering polymers.
The presence of hard and soft segments on their backbone and specific hydrogen bond …

A series of super-soft polyurethanes was prepared by synthesizing lightly crosslinked
polyurethane with low isocyanate: hydroxyl ([NCO]:[OH]) molar ratios. The starting materials …

In the present work, the degradation behavior of some polyurethane (PU) membranes
exposed to artificial weathering environment for different exposure time was studied. The …

Segmented polyurethanes, based on PCL-PEG-PCL copolymers, 1, 4-diisocyanatobutane
and l-glutathione oxidized, used as chain extender, were synthetized. Three different …

Polyurethane coatings were synthesized through polyaddition polymerization using various
polyols. These polyols included polypropylene glycol with different molecular weights, such …

Polyurethane moisture-curable resins obtained from isophorone diisocyanate (IPDI) and
polypropylene glycol (PPG) with different molecular weights (400, 1000, and 2000 g/mol) …

Hybrid resin from polyurethane-/polysiloxane-modified epoxy (PPME) has been synthesized
by using palm oil-based polyol as the polyurethane component. The palm oil-based polyol …

Various embodiments provide epoxy modified fluorinated urethane compositions that may
provide desirable bulk mechanical properties of conventional coatings, adhesives, or …
