Flame retardants, health support, and fine chemicals. Evolving product-manufacturing in the three business fields.

A lot of our products, which started in our bromination technologies, have evolved into the three business fields of “Flame Retardants”, “Health Support”, and “Fine Chemicals”, and our “Fine Chemical Business” has further developed into the fields of “Functional Materials”, “Electronic Materials”, and “Pharmaceuticals.”

Flame Retardant Business

Manac produces flame retardants added to plastics used in household appliances, office automation equipments, IT equipments, automobiles, etc. We also provide high performance flame retardants for special applications.

Flame Retardants for Office Automation Equipment

Flame retardants are Manac’s main business field in which we have been involved for more than forty years.
