Kynol NOVOLOID FIBERS
Kynol, generally known as novoloid fiber, is characterized by its high flame and chemical resistance. Novoloid fiber technology was initially developed in the United States with commercial production facilities later established in Japan. End uses for Kynol are varied and business development is focused primarily on specialty applications.
Made from an organic formula derived from three-dimensional cross-linked phenolic resin, Kynol exhibits unique properties that provide a distinct advantage in applications as diverse as electric arc protection, gaskets, mechanical packing and friction paper. Over the years, Kynol has also replaced asbestos in various industrial applications and is used as a precursor for carbon and activated carbon fibers materials.
Key characteristics of Kynol fibers, yarns and fabrics
･Inherently flame resistant (contains no halogen or phosphorus)
･Limited oxygen index (L.O.I.) between 30 - 34
･Exhibits minimal shrinkage and smoke emission when exposed to flame
･Will gradually char until carbonized completely
･Due to 3-dimensional cross-linked chemical structure, the fibers are thermoset and will not melt
･Can withstand short-term heat exposure in temperatures > 1000C
･When exposed to extremely high air temperature the fibers carbonize and gradually decompose
･In conditions where there is long-term heat exposure, Kynol is recommended for temperatures < 150˚C (300˚F) in air and < 250˚C (482˚F) in absence of air
･Strong resistance to acids, alkalis and organic solvents.
