ATMOSA - The Phthalic Anhydride Specialist in Europe


Atmosa Petrochemie was established in May 1995 by the Taiwanese Dahin Group after the acquisition of the Phthalic Anhydride plant from Chemie Linz, a former affiliate company of OMV.

This acquisition was part of Dahin Group’s strategic goal of upstream integration and global expansion. After playing a significant role within the Dahin group for a number of years, Atmosa has gradually shifted its focus to the European market.

Today, Atmosa is an independent company and one of the major producers of Phthalic Anhydride in Europe. The high quality of our product allowed Atmosa to establish itself as a reliable long-term supplier to most major resin and plasticizer producers in Europe.
