<Kuraray polyol> are premium polyester / polycarbonate polyols which are used as raw material for polyurethanes.
<Kuraray polyol> are amorphous and liquid with low viscosity at room temperature thanks to the methyl branch of MPD (3-Methyl-1,5-Pentanediol) in its structure.
Polyurethanes based on <Kuraray polyol> are more flexible than polyurethanes based on conventional polyols.
As illustrated below, we have a wide range of polyester / polycarbonate polyols.
