Foam stability and polymer phase morphology of flexible polyurethane foams synthesized from castor...

Foam stability and segmented polymeric phase morphology of polyurethane foams synthesized partially and completely from castor oil are investigated. Preliminary analysis of the impact of alterations in the polymeric phase on macroscopic stress dissipation in foams is also carried out. The stability and morphology show unique trends depending on the...

Temperature-dependent dynamic mechanical properties of magnetorheological elastomers under magnetic...

Both anisotropic and isotropic magnetorheological elastomer (MRE) samples were fabricated by using as-prepared polyurethane (PU) matrix and carbonyl iron particles. Temperature-dependent dynamic mechanical properties of MRE were investigated and analyzed. Due to the unique structural features of as-prepared matrix, temperature has a greater impact...

Transparent and Flexible Films of Thermoplastic Polyurethanes Incorporated by Nano-SiO2 Modified...

4,4′-Methylene diphenyl diisocyanate (MDI) played a dual role for preparing thermoplastic polyurethanes (TPU)/silica nanocomposites; both as monomer to synthesize MDI-capped poly(tetramethylene oxide) (PTMO) and as surface modifier of nano-SiO2 particles. Untreated and/or MDI-treated SiO2 were homogeneously incorporated into the resulting TPU...

RECYCLABILITY
Glycolysis recycling of rigid waste polyurethane foam from refrigerators

Rapid growth of rigid waste polyurethane (WPUR) foam from refrigerators attracts the attention all over the world. In this study, glycolysis was chosen to treat WPUR from scrapped refrigerators collected in Shanghai, China. Glycolysis reagents and catalysts were selected. The results indicated that the glycolysis efficiency of ethylene glycol (EG)...
