Started glass wool production
The first in Japan, we started glass wool production using the “spraying method.”
Launched Nittobo Dishcloth™
We started selling the Nittobo Dishcloth™, which would become a successful product.
Nittobo Dishcloth™ won the Good Design Long Life Design Award in 2015.
Invention of specialty chemical PAS
We were the first in the world to develop polymer compound polyamine sulfone (PAS), a functional polymer patented in seven countries and used as a dye-fixing agent, acid-corrosion inhibitor, and sizing agent for paper manufacturing.
Launched the glass cloth for printed wiring boards
We started production of glass cloth for printed wiring boards to meet the increasing demand in response to the advancement of computers and technology of integrated circuits (ICs).
Started production of a blood coagulation factor in vitro diagnostic reagent
Successfully synthesized and launched specialty chemical PAA® (first in the world)
We were the first in the world to develop an industrial production method of polyallylamine (PAA®), a functional polymer patented in many countries, including the U.S.A. It is used for various processing operations such as dyeing, textile treatment, paper manufacturing, metal surface treatment, and rust prevention.
Launched Special Glass T-glass
T-glass, characterized by its high strength and low thermal expansion, was initially used in composite materials and is now used in semiconductor package substrates for high-speed processing and highly reliable servers and smartphones.
