Applications

 

Itaconic Acid  (also called Methylene Succinic Acid) is a white crystalline carboxylic acid obtained by the fermentation of carbohydrates. It is soluble in water, ethanol and acetone. Unsaturated double bond makes a conjugated system with carbonly group. It is used in the field of;

Co-monomer to prepare acrylic fibers and rubbers, reinforced glass fiber, artificial diamonds and lens

Additive in fibers and ion exchange resins to increases abrasion, waterproofing, physical resistance, dying affinity and better duration

Water treatment system to prevent contamination by metallic alkali

As binder and sizing agent in non-weaving fibers, paper and concrete paint.

The end applications of itaconic acid and its esters include in the field of co-polymerizations, plasticizers, lubricant oil, paper coating. Carpets for better duration, adhesives, coatings, paints, thickener, emulsifier, surface-active agents, pharmaceuticals and printing chemicals.
