PANOX Oxidized PAN Fibers

PANOX is an oxidized polyacrylonitrile (PAN) fiber which does not burn, melt, soften or drip. As an internationally recognized industry standard for non-flammable textile fibers, PANOX can be used in many different fields as an effective protection against fire and heat. The LOI value of PANOX, at >45 %, is considerably higher than that of other fibres and corresponds to combustion class S-a according to DIN 66083.

The optimum fibers for textile processes

Our oxidized PAN fibers are extremely versatile and can be easily used in a wide range of different textile processes to produce high performing, economic, flame proof and insulating fabrics. We supply PANOX as continuous tow, crimped and non-crimped staple, and milled fiber with different fiber diameters, lengths, densities, and sizings.

High LOI value of > 45 %
Excellent fire class
High temperature resistance
Optimized for textile processing
Ideal blending and processing behavior

SGL Carbon's PANOX continuous carbon fiber tow

PANOX^® continuous fiber tow

PANOX continuous fibers are supplied as a 320,000 filament tow with a special lubricating sizing to improve stretch breaking and tow conversion into yarns for knitted and woven textiles. Continuous fiber tows are available in two different fineness levels.

PANOX^® crimped staple fibers

Crimped PANOX fibers are made from continuous fiber tow. They are supplied with a special sizing that improves cohesion. Together with a carefully optimized crimp level, this ensures that carding processes run continually and reliably, with good productivity. Crimped staple fibers are available in a range of lengths to suit different non-woven processes and equipment.

PANOX^® non-crimped staple fibers

Non-crimped staple fibers are used in compounding and molding applications to provide a textured surface appearance to interior components in automotive, rail, and marine applications. As well as improving the cosmetic appeal of these surfaces, the PANOX fibers also improve the fire protection and chemical resistance of these parts.

PANOX^® milled fibers

Milled PANOX fibers are used as a non-hazardous and heat resistant organic fiber filler for brake and friction compounds. These fibers are an excellent alternative to more hazardous materials such as asbestos. Typical applications include automotive brake pads, high-performance motor sport brake pads, brake linings for trains, and friction linings for elevators.
