Why choose Arkema's Specialty Polyamides

Supply security

Guaranty of the best supply security for our clients is an everyday concern. As such, vertical integration in all key monomers and feedstocks is a pillar of our strategy. As a world leader in biosourced specialty polyamides, Arkema has developed a leading position in castor oil feedstock and monomers. In 2012, Arkema acquired Casda Biomaterials, the world leader in sebacic acid derived from castor oil. In 2013, Arkema signed a joint venture agreement with Jayant Agro, the world largest castor oil producer.


Worldwide Presence

Thanks to the wordwide repartition of its production sites and R&D centers, the Specialty Polyamides division ensures a local presence on three continents: Europe (France), North America (USA), Asia (Japan and China).
