Product Name:Triethylene glycol diheptanoate
English Name:Triethylene glycol diheptanoate
CAS No.:7434-40-4
Aliases:TEG diheptanoate, Triethylene glycol dienanthate, Triethylene glycol bis(heptanoate)
Molecular Formula:C20H38O6
Physical Properties:Colorless to light yellow transparent oily liquid with a slight characteristic odor. Molecular weight 374.51, density approx. 0.98 g/cm³ at 20°C, boiling point approx. 235°C at 1.3 kPa, flash point approx. 205°C. Insoluble in water; soluble in ethanol, acetone, toluene and other organic solvents. Low viscosity, low volatility and good thermal stability.
Uses:This product is a synthetic ester plasticizer mainly used in polyvinyl chloride (PVC) and cellulose resin products, effectively improving flexibility, low-temperature resistance and processability of the finished products. It also serves as a base oil component for high-temperature lubricants, enhancing lubricating performance, and as a coalescing agent in coatings to promote film formation. Additionally, it can be used in formulations of textile auxiliaries and mold release agents.
