Applications of Industrial Grade 1,3-Propanediol
Core Monomer for Producing High-Performance Polyester PTT
The most important and valuable application of industrial-grade 1,3-propanediol is its polymerization with terephthalic acid to produce a novel polyester-polypropylene terephthalate (PTT). PTT fibers combine the elasticity of nylon, the dimensional stability of polyester, and excellent dyeing resilience, making them widely used in high-end sports fabrics, carpets, engineering plastics, and packaging materials.
Raw Material for Polyurethanes, Hot Melt Adhesives, and Unsaturated Polyester Resins
Due to the reactivity of its di-terminated hydroxyl groups, industrial-grade 1,3-propanediol is a crucial component in the synthesis of polyurethane elastomers, polyester polyols, hot melt adhesives, and unsaturated polyester resins for powder coatings. It effectively modifies the flexibility and hydrolysis resistance of resin segments, enhancing the overall mechanical strength of downstream adhesives and coatings.
Antifreeze, Coolant, and Heat Transfer Fluid Components
This product has a low freezing point, a high boiling point, and is completely miscible with water. Industrial-grade 1,3-propanediol can be used as a base component in environmentally friendly antifreeze and industrial coolants. It can also be used to formulate heat transfer fluids for solar cells, HVAC systems, etc., partially replacing traditional ethylene glycol.
Plasticizers and Additives in Coatings, Inks, and Solvents
Industrial-grade 1,3-propanediol, as an excellent solvent and coupling agent, is used in coatings and ink systems to enhance resin plasticity, lower film-forming temperature, and improve formulation stability. It can also be used as a carrier and solubilizer for pesticides and dyes, improving product dispersibility and absorbability.
Fine Chemicals and Organic Synthesis Intermediates
Industrial-grade 1,3-propanediol is a key starting material for the synthesis of pharmaceutical intermediates, novel antioxidants, functional surfactants, and demulsifiers. It can also be used to prepare various fine organic chemical products such as heat stabilizers, plasticizers, and printing auxiliaries.
