Vegetable-origin foam employed in dye extraction in tanning and leather processing facilities
(Associação Brasileira de Polímeros, 2009)
This study addressed the use of conventional and vegetable origin polyurethane foams to extract C. I. Acid Orange 61 dye. The quantitative determination of the residual dye was carried out with an UV/Vis absorption ...

Assessment of multiaxial mechanical response of rigid polyurethane foams
(Springer, 2013-04-12)
Multiaxial deformation behavior and failure surface of rigid polyurethane foams were determined using standard experimental facilities. Two Commercial foams of different densities were assayed under uniaxial, biaxial and ...
Rapeseed oil-based polyurethane foams modified with glycerol and cellulose micro/nanocrystals
(Wiley, 2015-03-10)
A rapeseed oil-based polyol (ROPO) was synthesized using chemical modification of the rapeseed oil (RO) by epoxidation reaction followed by oxirane ring-opening with diethylene glycol. The ROPO was used in the formulation ...
