Pongmuksuwan, Pornlada; Harnnarongchai, Wanlop published the artcile< Synthesis and characterization of soft polyurethane for pressure ulcer prevention>, Quality Control of 112-63-0, the main research area is pressure ulcer prevention polyurethane preparation.
A series of super-soft polyurethanes was prepared by synthesizing lightly crosslinked polyurethane with low isocyanate:hydroxyl ([NCO]:[OH]) molar ratios. The starting materials were polymeric isocyanate (pMDI), polypropylene glycol (PPG), and 1,1,1-tris(hydroxymethyl)propane (TMP). The effects of the [NCO]:[OH] molar ratio and concentrations of the crosslinking agent TMP on the crosslink d. and the thermal, dynamic-mech., and mech. properties of the polyurethanes were determined In addition, TMP generates chem. and phys. crosslinks within polyurethane; therefore, data calculated using the Flory-Rehner equation and the rubber elasticity were compared. The success of the reaction between pMDI and PPG was confirmed using Fourier-transform IR spectroscopy. The synthesized polyurethanes exhibited a mixing phase between soft and hard segments. The addition of TMP increased the crosslinking d., resulting in increased glass transition temperature, tensile properties, and hardness; however, the pressure distribution was suppressed. The synthesized polyurethane showed effective properties for pressure ulcer relief applications.
Polymer Testing published new progress about Crosslinking agents. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Quality Control of 112-63-0.
