Polyurethane (PU) foams reinforced with bamboo fiber sources in China, ie, bamboo fiber,
bamboo α-cellulose fiber, and bamboo nanocellulose fiber, were prepared and their physico …

Bamboo residues were liquefied by using a solvent mixture consisting of polyethylene glycol
400 and crude glycerol (4/1, w/w) with 98% sulfuric acid as catalyst at 160° C for 120 min …

The study investigated the effect of lignocellulosic biomass filler decayed by brown-rot fungi
on the preparation and properties of polyurethane (PU) foam. The properties of brown-rotted …

Because of the environmental impact of fossil fuel consumption, soybean-based
polyurethane (PU) foam has been developed as an alternative to be used as the core in …

Polyurethane (PU) composite foams were prepared by pour method with soy-based polyol
(soyol). Foams were tested for the evaluation of mechanical properties and cell …

Various polyurethane (PU) foams were prepared by in situ reaction of isocyanate and soy-
based polyol. The effects of wood fiber and microclay on the foam morphologies …

In the study walnut shells (WS) and silanized walnut shells (S_WS) were used as cellulosic
fillers for novel polyurethane (PU) composite foams. The impact of 1, 2 and 5 wt% of WS and …

Flexible polyurethane (PU) foams with different loading mass fraction (0%–2.0%) of fumed
silica were synthesized by free-rising foaming method. The addition of 1.4% fumed silica …

Liquefaction of sawdust was studied using glycerol and methanol as mix solvents. A new bio‐
polyol product consisting of high purity multi‐hydroxy compounds was obtained by …

Polyurethane foam manufacturing depends on its materials and processes. A polyol that
contains primary alcohol is very reactive with isocyanate. Sometimes, this may cause …
