Polycarbonate Diol Raw Material 1,5-pentanediol

Polycarbonate diol raw material 1,5-Pentanediol (CAS 111-29-5) is a renewable, bio-based chemical used across a wide range of high-value industrial applications. Extracted from non-food biomass-specifically corncob-this compound is a key sustainable alternative to fossil-based raw materials. It is a transparent, low-viscosity liquid and plays a crucial role in polymer synthesis, especially for polycarbonate diols, which are central to modern polyurethane systems.

Polycarbonate diol raw material 1,5-Pentanediol in our plant is manufactured through a refined biotechnological process using corncob as the raw material. Corncob, a cellulose-rich agricultural byproduct, provides an ideal source for creating bio-based chemicals without interfering with food chains. The production process is designed to minimize waste, reduce emissions, and support the development of a bio-economy. This renewable route results in a lower carbon footprint compared to traditional petrochemical-derived alternatives.
