The world-renowned
high-
performance fiber,
“Kynol”.
What is Kynol?
Kynol is a high-performance novoloid fiber with a three-dimensional network structure which originates from the reactivity of phenol. Initially developed in 1968 as a part of space technology development in the United States, full-scale industrial production began in 1982. GCI is currently the only manufacturer of the novoloid fiber in the world. The Kynol product lineup includes (1) high-performance fibers, (2) carbon fibers, and (3) activated carbon fibers.
Advantage of Kynol
-
01Excellent flame resistance and non-meltability
Kynol is characterized by its high flame resistance, non-melting even at high temperatures, and low heat shrinkage.
-
02Low smoke・gas emission
Even when exposed to flame, Kynol doesn’t melt. When it is carbonized, it only emits a small amount of smoke.
Since it consists only of Carbon, Hydrogen and Oxygen atoms, it emits extremely small amounts of toxic gas when decomposed. -
03Chemical resistance
Kynol is resistant to many chemicals, especially strong acids.
-
04Amorphous carbon fiber
When Kynol is carbonized,it has a non-crystalline (amorphous) structure, low strength and flexible characteristics.
-
05Outstanding activated carbon performance
Kynol is a raw material for high-performance ACF (Activated Carbon Fiber). It can be used as an ACF with an ultra-high specific surface area that cannot be achieved by other precursor materials.
