Product Information

The power of chemistry for a bright future.

Tosoh Finechem is a manufacturer of fine chemicals that aims to create new technologies and supply products in the fields
of polymerization catalysts for polymers, electronic materials, and pharmaceutical intermediates, based on its core technologies
in halogen and organometallic chemistry.

Organic aluminum such as alkyl aluminum and aluminoxane, our main products, are indispensable as polymerization catalysts
for polyolefins and synthetic rubbers.
In addition, based on the chlorine and bromine produced in plentiful volume by the vinyl isocyanate chain of Tosoh Corporation,
a comprehensive chemical manufacturer, we offer a broad range of derivatives containing fluorine, chlorine, bromine, or iodine,
along with high value-added products.

We endeavor to continue as a truly reliable company by responding to the needs and requirements of our customers.
To this end, we strive to manufacture high-quality products and build an ever-dynamic production and sales system.

The power of chemistry for a better future.

We are more committed than ever to technological innovation and to delivering products that meet customer needs.
