Asahi Kasei Finechem Co., Ltd.

Manufacture's Feature

Nissei Chemical Industry was established in 1960, as a member of the Asahi Chemical (Asahi Kasei) Group, with the task of producing, as first in the world, dying improver (sodium Methallyl sulfonate) for acrylic fibers. Since then, the company has supplied demand on both the Japanese and world markets as a general manufacturer of sulfonate monomers.
Through good business relations with many companies including Asahi Kasei, we have focused on the development and production of various types of materials and intermediates in diverse fields, in order to meet a wide range of needs.
In anticipation of the 21st century, the company changed the name to ASAHI KASEI FINECHEM CO., LTD. and is now posed to take a new step forward.
We will be positively involved with new businesses together with Asahi Kasei Corporation and at the same time, will pursue refinement of products such as specialty chemicals and intermediates making the best of our mobility as an expert of organic chemical synthesis.
We will do our best to improve experimental synthesis and production technologies and to develop functional materials that satisfy user requirements. At the same time we enforce through quality control that places the customer first. As an expert in specialty chemicals, we will take the initiative in implementing changes of the world.
