NITIVY
NIVITY SV Series Braided Sleeving
Model: SV Series
Heat-Resistant Fiber
NITIVY ALF™ is a continuous alumina fiber that was developed based on our vinylon (PVA fiber) dry spinning technology.
The yarn, which is made of bundles of filaments formed from fine crystal grains, is highly flexible and processable into various products such as fabrics and sleevings without the aid of other fibers.
NITIVY ALF™ has a wide range of applications thanks to its excellent thermal resistance, high strength and modulus, and electrical insulation properties.
