Product Introduction
Industrial grade 1,3-propylene glycol (CAS No. 504-63-2) is a widely used basic diol chemical raw material. With a purity of ≥98% and key characteristics of low toxicity and high stability, it primarily serves industrial applications such as polymer synthesis, industrial solvents, and antifreeze systems.

Overview
Industrial grade 1,3-propylene glycol, also known as 1,3-Propanediol (PDO), is a colorless, high-purity diol compound containing two hydroxyl functional groups. As an important multifunctional chemical raw material, it offers excellent chemical stability, low volatility, high boiling point, and good compatibility with various organic compounds. These characteristics make it a valuable ingredient for industrial formulations and the production of advanced materials.
Industrial grade 1,3-propylene glycol is commonly used as a building block in polyester, polyurethane, coatings, resins, and other specialty chemical applications where stable performance and reliable quality are required.
Qingdao Jinforest Chem Tech Co., Ltd. supplies high-quality industrial chemicals with professional quality control systems, export experience, and complete technical documentation support, helping global customers obtain stable and reliable raw material solutions.

Description
The molecular structure of Industrial Grade 1,3-Propylene Glycol contains two hydroxyl groups, which provide strong chemical reactivity with carboxylic acids, isocyanates, and other functional compounds. This feature allows it to participate effectively in polymerization reactions and makes it suitable for producing polyester materials, polyurethane systems, and specialty resins.
For manufacturers, this means improved flexibility, enhanced material performance, and greater formulation possibilities.
As a reliable Industrial Grade 1,3-Propylene Glycol supplier, Qingdao Jinforest Chem Tech Co., Ltd. focuses on delivering consistent product quality through strict quality management procedures. Each production batch is carefully monitored from raw material inspection to final product testing. Professional documents such as COA and MSDS can be provided to support customer quality evaluation, international transportation, and regulatory compliance. Our products are exported to markets across Europe, North America, Southeast Asia, the Middle East, South America, and other regions.

Key Advantages of Industrial Grade 1,3-Propylene Glycol
Excellent downstream polymer properties endow materials with superior characteristics
As the core monomer of polypropylene terephthalate (PTT), industrial grade 1,3-propylene glycol enables polyester fibers and plastics to exhibit unique tensile recovery, a soft hand feel, and good dyeability, demonstrating outstanding performance in high-end textile fabrics, carpet yarns, and engineering plastics. The polyurethanes, resins, and coatings synthesized with it also possess balanced mechanical and processing properties.
High purity and low impurities ensure stable production processes
Industrial grade 1,3-propylene glycol typically possesses a purity of over 99%, with some products reaching 99.8% or even higher, while also exhibiting low water content and a clear color. This high standard of quality ensures the stability and controllability of the polymerization process, effectively reducing side reactions and improving the quality and yield of the final product..
Excellent Solubility and Broad Compatibility
This product is completely miscible with water, ethanol, and many organic solvents, and has low volatility. It can be used as a highly efficient solvent, coupling agent, or reaction medium in various industrial formulations such as de-icing agents, heat transfer fluids, coatings, polyurethanes, and printing inks, helping to improve system homogeneity and processing rheology.
Outstanding Cost-Effectiveness, Dominating Multiple Industrial Markets
The cost of industrial grade 1,3-propylene glycol is significantly lower than that of cosmetic-grade 1,3-propylene glycol, meeting the consumption needs of major industrial sectors such as PTT, polyurethane, resins, and de-icing fluids at a more economical price. It holds an absolute dominant share of approximately 83% in the entire 1,3-propylene glycol product market, making it a highly efficient choice that balances performance, cost, and supply stability.
