Dynamic mechanical analysis of novel polyurethane coating for military applications

Analysis of dynamic mechanical, thermal and surface properties of poly(urethane-ester-siloxane) networks based on hyperbranched polyester

“…The difference between G′ at temperatures below T gH and in the rubbery plateau is also correlated with the crosslinking density of networks. This difference is the lowest for PU2-15, indicating that this sample has the highest crosslinking density [31].…”

Biobased Polyurethane from Palm Kernel Oil-Based Polyol

“…This is expected since it is a water-blown PU system where water has poor properties i.e. boiling point and k-factor compared to its industrial counterpart, chlorofluorocarbon, CFC (Crawford & Escarsega 2000). Low thermal conductivity is normally contributed by the low boiling point of the blowing agent such as CFC and finer cell structure of the foam (Hardings 1965, Frisch 1985, Hepburn 1991.…”

Polyurethane Networks Nanoreinforced by Polyhedral Oligomeric Silsesquioxane

“…[24,25] It has been proposed that the broadening of the loss peaks could prefigure superior mechanical properties, such as damping properties. [23] Thermal Stability Shown in Figure 3 are the TGA curves of the control PU and its nanocomposites with POSS. Within the experimental temperature range, the TGA curves of all the samples displayed similar degradation profiles, suggesting that the existence of the POSS did not significantly alter the degradation mechanism of the matrix polymers.…”
