Effects of hydrotalcites and tris (1-chloro-2-propyl) phosphate on thermal stability, cellular...

Isocyanate-based polyimide foams (PIFs) with different dosages of liquid tri (1-chloro-2-propyl) phosphate (TCPP) and micro-sized hydrotalcites (LDHs) particles alone, as well as different mixing ratios of TCPP and LDHs, were prepared via a one-step process in this work. Limiting oxygen index (LOI) and cone calorimeter test (CCT) results indicated...

Bio-based polyurethane foams toward applications beyond thermal insulation

In this work the preparation of viscoelastic bio-based polyurethane foams (PUFs) using polyols obtained via acid liquefaction of coffee grounds wastes has been optimized. In a first stage, the effect of different ratios of isocyanate content to hydroxyl number (0.6, 0.7 and 0.8) and of three distinct percentages of catalyst (3%, 5% and 7%) on the...

Development of polyetheramide based corrosion protective polyurethane coating from mahua oil

Mahua (Madhuca indica) is a widely grown tree in tropical regions of India. The estimated annual production of it is higher as compared to karanja oil and neem oil. In the present work mahua oil was reacted with diethanol amine resulting in the formation of mahua oil fatty amide (MFA) which was further reacted with bisphenol-A forming mahua...

Synthesis, characterization and application of AFC-based waterborne polyurethane

A novel anionic AFC-based waterborne polyurethane was synthesized by importing the fluorescent agent 7-amino-4-(trifluoromethyl)coumarin (AFC) into the polyurethane chains. Structure of the WPU-AFC was confirmed by Fourier transform infrared spectroscopy (FTIR) and UV-visible absorption spectroscopy. Number average molecular weight and average...
