Adipic Acid

Our high purity Adipic Acid (AA) is an important intermediate in the production of Nylon 6.6 but also used for a wide range of applications: resins, adhesives, coatings, plastics, paper, plasticizers, and detergency. We offer Adipic Acid in the form of powder (density of untamped powder: 0.63 - 0.65 g/cm³).  

Specifications

Adipic Acid is available in the form of white crystalline powder (density of untamped powder: 0.63 - 0.65 g/cm³). The storage should respect certain conditions:  

  • Protected from humidity and bad weather conditions  

  • Stored a well-ventilated area  

  • Away from any source of heat and ignition. 

Transport & Packaging 

Adipic acid is transported in 25 kg bags, standard B type 500 or 1000 kg big bags, 1000 kg C type anti-static big bags. It can be also transported in bulk containers. Air pulsed bulk product is conveyed into road tanker or railway tank. Please consult your local Sales Representative for other packaging options.  

Applications 

Adipic Acid is mainly used as a monomer for the production of polyamide 6.6 pellets and other polyamides or polymers in the field of Engineering Plastics, Textile Fibers and Industrial Yarns as well as Polyurethane for flexible and semi-rigid foams.  

Adipic Acid is also used as an intermediate for organic synthesis in the field of lubricants, plasticizers, wet strength resins, coatings, adhesives, sealants and elastomers, perfumes and cosmetics.  

In addition, Adipic Acid is used in formulation in the field of pH regulator and buffer and used as laboratory chemicals.
