Our Vision


Basic Chemicals Business

Intermediate bulk containers (IBCs)

We propose use of 1,000 liter IBCs instead of 200 liter drums or small capacity lorries.

Fine Chemicals Business

Phosgenation reactions

We receive orders to carry out custom synthesis of chemicals derived from phosgene, which is difficult to manage on a small-lot production basis. Four sets of reaction vessels (400, 2,000, 4,000, and 6,000 liter capacity) are capable of handling phosgenation.
