NITIVY ALF™

About NITIVY ALF™

NITIVY ALF™

NITIVY ALF™ is continuous Alumina Fiber that was developed by Nitivy's vinylon(PVA fiber) dry spinning technology.
NITIVY ALF™ is Boron-free Alumina-Silica fiber that is composed of Al2O3 72% and SiO2 28%. Al2O3 and SiO2 are commonly known as representatives of stable metal oxide.
NITIVY ALF™ is polycrystalline filament whose crystal type is gamma alumina and amorphous silica. The yarn is made up of thousands of fine filaments with a diameter of 7micron, which gives it excellent flexibility and allows it to be transformed into various textiles without the aid of other fiber or wire inserts.

Fabrics,tapes,sleeves,sewing thread and cordage are typical products.
At present, there is a growing interest in NITIVY ALF™ filament yarn for use in a wide range of applications which require high temperature operation environments.
