RESINDION SRL is a fully owned subsidiary of MITSUBISHI CHEMICAL CORPORATION, Tokio (Japan)


Founded in Italy in 1959, Resindion S.R.L. started the production of RELITE ion exchange resins in the plant located in Binasco (Milan area).

Mitsubishi Chemical Corporation, one of the worldwide leaders in the ion exchange and adsorbent resins production, merged Resindion S.R.L. in 1989.

As result of a quite successful integration on standard Relite and Diaion Ion Exchange Resin, Resindion S.R.L. moved across a process of innovation that brought to the today’s production of new functionalized media for the Bioprocess area of application:
