Document Type and Number:
WIPO Patent Application WO/2020/080485
Kind Code:
A1
Abstract:
Provided are: a polyol composition which, when stored for a long period, suffers no hard caking; and polyurethane foam obtained from the polyol composition. The polyol composition comprises a polyol compound, a blowing agent, a filler, and fine metal oxide particles, wherein the blowing agent comprises a hydrofluoroolefin and the fine metal oxide particles in analysis by time-of-flight secondary ion mass spectroscopy have a ratio of the count of OH ions of the metal of the fine metal oxide particles to the total count of all the ions of 0.1 or less.
