3-Methyl-1,5-pentadiol (MPD)

Product Description

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.

Handling Information

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.
