CAS: 64-19-7
Glacial Acetic Acid (GAA), a widely-accepted colorless liquid with a disagreeable odour used as a chemical substance in large quantities. This is another strong version with high purity and an important starting material for acetic anhydride, acetate esters etc. GAA is a concentrated version of the diluted acetic acid which is much more useful for industrial situations. Its role is vital in enhancing product quality and performance across numerous applications.

Application in Plastic Rubber industry
Glacial acetic acid is very important with respect to a solvent as well asChemical Intermediate. These compounds are very important in the production of cellulose acetate, a plastic product material that we use widely made out of such as film, fibers, and molded parts. Moreover, GAA is also used as plastic filler increasing the flexibility and reliability of rubber material so it could perform in different applications.
Others Industries:
Apart from plastic and rubber industry, Glacial Acetic Acid is used in many other significant industries as follows:
Petroleum & Gas: Used in drilling fluids, a solvent for oil recovery processes.
Building: Acts as bond breaker/intermediary of construction materials.
Cosmetics and Personal care: Used as pH adjusting agent in cosmetic formulation
Food & Nutrition: A food preservative, flavoring agent.
Pharma: Used for manufacturing intermediates of pharmaceuticals
Agriculture: Used in Herbicides, pesticides.
