Viscoelastic polyurethane foams production with different contents of KL and PKO were tested with kraft lignin dispersions in methoxy polyethylene glycol and a mixture of palm kernel oil with MPEG. The effect of the dispersed KL on the foam structure, foam growth profile, foaming reactivity, mechanical stability, and final properties of VPFs was investigated. The appearance of the VPF made with KL dispersion in MPEG/PKO was similar to that of control VPF foam. When compared to the control, KL's 3. 9 p. of KL's shrinkage values decreased by about 4 times. The presence of the KL and PKO in the foam samples did not increase the burning rate of the foam samples compared to the control foam, with KL and PKO. The dispersion of KL by MPEG and PKO in a mixture of MPEG and PKO has been argued as an alternative for merging portions of KL and PKO into VPF.
