General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. This product can replace highly toxic diluents in membrane preparation and thus aligns with "Less Hazardous Chemical Syntheses". Click here for more information.

Application

Triacetin can be used as:
  • An additive in the preparation of flax fiber-polylactic acid (PLA) composites due to its compatibility with the polymer and ability to increase the elongation of the plastic.
  • A reactant in the transesterification reaction with methanol using various catalysts.
