Terephthalic acid uses
One of the most important applications is plastic manufacturing and producing saturated polyesters. Here are some other uses of this substance:
Textile industries
Textile industries use polyester fibers. It is interesting to know that terephthalic acid is used in manufacturing polyester fibers.
Paint industries
Paint industries are used as a carrier compound in the formulation of paints. The role of the carrier compound is to disperse other components in the formulation of paints. This compound helps to control the viscosity of the product and makes it suitable for different applications.
Pharmaceutical industries
It is used as a raw material in the formulation of certain drugs. It is also used in the packaging of different drugs.
Terephthalic acid + ethylene glycol
The process of PET production needs both terephthalic acid and ethylene glycol.
“When heated together under the influence of chemical catalysts, ethylene glycol, and terephthalic acid produce PET in the form of a molten, viscous mass that can be spun directly to fibres or solidified for later processing as a plastic.”
Purified terephthalic acid MSDS
