Our Anhydrides Product Range
Phthalic Anhydride (PA)
Phthalic Anhydride is used in the production of phthalate plasticizers, alkyd resins, unsaturated polyester resins, dyes, and pigments.
It is an important raw material for plasticizer and resin manufacturing. Its purity and physical properties are relevant when assessing the material for a specific production process.
Maleic Anhydride (MA)
Maleic Anhydride is used in unsaturated polyester resin production and the manufacture of other chemical intermediates.
Its downstream applications include the production of butanediol (BDO), tetrahydrofuran (THF), gamma-butyrolactone (GBL), coatings, and lubricant additives.
PA and MA serve different chemical production requirements. Selecting the correct product starts with identifying the intended downstream process.
