3-Methyl-1,5-pentadiol
(MPD)
MPD (3-Methyl-1,5-pentanediol) is low viscosity
liquid with an unique molecular structure: a branched aliphatic diol
with two primary hydroxyls. It offers significant advantages in a
vast range of applications.
MPD is liquid even at very low temperatures. It
yields very low viscosity derivatives. It provides excellent handling
advantages particularly in polyurethane resin applications.
MPD's blanched molecular structure yields non crystalline polymers
such as polyester and polyurethane resins. The unique non crystallizing
nature of MPD-adipate based polyurethane resins provides significant
advantages to manufacturers and consumers of these resins such as
softness, excellent durability, broader solvent compatibility, good
transparency, excellent stain resistance and improved mold resistance.

MPD and Kuraray Polyol P-series are stable materials.
However they should be stored away from strong mineral acids, dehydrating
agents and strong oxidizing agents. If a low water content is important,
MPD and Kuraray Polyol P-series should be protected against excessive
exposure to atmospheric moisture and stored under a nitrogen blanket.
Keep away from heat, sparks and flame.
