High purity boron trifluoride cylinders
High purity boron trifluoride cylinders

We manufacture high purity boron trifluoride and its compounds as catalysts to promote chemical reactions called "polymerization" which are required when manufacturing a range of chemicals and pharmaceutical intermediates.
In 1963, Stella Chemifa was the first company to produce boron trifluoride gas for industrial use in Japan.
Currently, we are the only company in Japan manufacturing boron trifluoride gas. Taking advantage of this exclusivity, we supply a broad variety of products to chemical and pharmaceutical manufacturers both in Japan and overseas.

GMP-Compliant Products

Our plant which manufactures GMP-compliant products (Izumi Factory)
Our plant which manufactures
GMP-compliant products (Izumi Factory)

GMP (Good Manufacturing Practices) is a standard for manufacturing control and quality control of chemical agents and quasi-chemical agents. It is based on the principles of "reducing human errors to the lowest level," "preventing contamination and product quality loss" and "designing systems to assure high product quality."
Previously, we had been manufacturing and selling tin fluoride, a raw material for toothpaste. In anticipation of market expansion, we completed measures to comply with GMP and we became the first manufacturer in Japan producing tin fluoride as the raw material for toothpaste.
We are also developing new applications.(e.g.,hoof sterization).
