Product Description
1,3-Propanediol （PDO）
1,3-Propanediol utilizes native Shell technology, with an annual production capacity of 72,000 MT, and uses ethylene oxide as a raw material. Compared to bio-fermentation processes using glucose and glycerol, the ethylene oxide method offers a more stable production process, fewer impurities, lower costs, higher product purity, and stronger batch stability, making it suitable for high-end polyester synthesis.
As a key monomer in PTT polymerization, 1,3-Propanediol significantly improves the elasticity, softness, and stain resistance of materials, and is widely used in high-performance fibers and engineering plastics. Furthermore, its excellent moisturizing properties make it suitable as a humectant in cosmetics. The company also uses bioethanol to produce syngas, enabling the production of bio-based PDO to meet the needs of diverse customer groups.
