Product Application Of 1,3-Propanediol CAS#504-63-2

1,3-Propanediol /PDO/ is mainly used for making polytrimethylene terephthalate polymer, which is used in fibers and fabrics, for example, carpets, textiles, engineering thermoplastics, nonwovens, films, and monofilaments. PDO finds also use as chain extender in thermoplastic polyurethanes, where it contributes to improved thermal, hydrolytic and dimensional stability. In adipate polyesters with other diols these diols are partly substituted by 1,3-propanediol to break crystallinity in order to obtain liquid polyester polyols. In polyesters for powder coatings PDO improves the flexibility but lowers the glass transition temperature somewhat. PDO finds also uses in cosmetics and personal care products, engine coolants, and solvents for ink-jet and screen inks.
