Rigid palm oil-based polyurethane foam reinforced with diamine-modified montmorillonite nanoclay

Soy-based Polyurethane Foam Reinforced with Carbon Nanotubes

The objective of this research is to develop soy-based polyurethane (PU) foam product reinforced with carbon nanotubes. The shortage of petroleum and the increasing concern on environmental issues have resulted in an interest in using renewable substances as building blocks for polymer applications. Multi-walled carbon nanotube (MWNT) was used in this study to reinforce the soy-based polyuretha...

Nonlinear Optical Properties of Rigid Polyurethane Foam/SiO2 Nanocomposite

Polyurethane closed cell (PUCC)/SiO2 nanocomposites have been prepared by using in situ polymerization approach. The third-order optical nonlinearities of PUCC/SiO2 nanocomposites, dissolved in DMF are characterized by Z-scan technique at the measurement wavelength of 532 nm. The nonlinear refractive (NLR) indices and nonlinear absorption (NLA) coefficients of samples were calculated from close...

Biobased Polyurethane from Palm Kernel Oil-Based Polyol

Glycols in Polyurethane Foam Formulations with a Starch–Oil Composite

A dry starch–oil composite was blended with each of three glycols; ethylene, polyethylene, and propylene, and then reacted with isocyanate to produce polyurethane foams. The liquid glycols permitted the dry composite to blend well with the other ingredients in the foam formulations. Infrared spectra confirmed the presence of urethane structures in the composite–glycol foams. Polyethylene glycol...

Oil-Palm-Fibre Reinforced Phenolformaldehyde Composites

Thermophysical properties such as, effective thermal conductivity (A,,) and effective thermal diffusivity (Xc) of untreated reinforced phenol formaldehyde with different weight per centages of oil-palmfibre (x) are measured simultaneously using the transient plane source (TPS) technique between 80 to 120"C. The composites investigated contain 20, 30 and 50 weight per centage of oil-palm-fibre. ...
