The kinetics of catalyzed by dibutyltin dilaurate reaction of polyurethane foam synthesis infused with 1 wt% of fillers was studied in dependence of Type 1D (nanosized [multi‐wall carbon nanotubes] or macrosized [carbon fibers]) or 2D (thermoexpanded graphite) carbonaceous fillers by IR spectroscopy and optical microscopy. It is shown that the foaming reaction has two stages: the first stage being a first‐order reaction, and the second stage a second‐order reaction. The mean diameter of the bubbles and the bubble size distribution has been determined during the process of foaming. It is shown that the presence of 2D fillers leads to a decrease in the mean diameter of the bubbles. POLYM. ENG. SCI., 59:941–948, 2019. © 2018 Society of Plastics Engineers
