One of the largest benefits of ZOLTEK OX products are their versatility. ZOLTEK OX is available for all forms of textile processing including: needle punching, stitch-bonding, hydroentangling, thermal bonding, chemical bonding, air-laying, wet-laying, ring spinning, stretch-breaking, weaving, knitting and braiding. End uses include aircraft brake performs, transportation heat and flame blocking layers, thermal, acoustical and vibration insulation liners, flame resistant apparel, intumescent mesh and as raw materials for carbonized and graphitized yarns, fabrics and felts.
Aircraft Brakes
ZOLTEK OX fiber is the key component in the production of carbon aircraft brakes. ZOLTEK OX fiber is processed through conventional textile equipment and transformed into preforms which are converted into carbon brakes through a series of manufacturing operations. In comparison to steel brakes, ZOLTEK OX based carbon brakes offer twice as many landings per overhaul, similar life-cycle costs, significant weight savings, higher energy absorption capability and the ability to handle up to 2000°F during landings.
Fireblocking Layer Fabric
ZOLTEK OX fiber is the key component in woven and nonwoven fireblocking layer (FBL) fabrics for aircraft, rail and marine seating applications. ZOLTEK OX is blended with para-aramid and other FR fibers to provide the optimum FBL solution. ZOLTEK OX is the most cost effective fiber for this FBL application and it contains no halogens, provides outstanding flame resistance, and generates very low toxic gas emissions when exposed to flame; all of which are essential elements for this demanding application.
Automotive Noise, Heat and Vibration Liners
ZOLTEK OX fiber is blended with polyester fiber to create felts for use in noise, heat and vibration liners for automotive applications. These applications require excellent heat and thermal aging resistance in the high temperature compartments of an automobile and have the preferred black color for this end use.
Welding Drapes and Heat Insulating Blankets
ZOLTEK OX fiber is used in welding drapes, welding aprons, welding curtains and in thermal insulation blankets. It provides excellent resistance against sparks and flame, because it does not shrink when exposed to high temperatures
Flame and Electric Arc Resistant Apparel
ZOLTEK OX fiber blends can be dyed to produce soft and comfortable knit and woven flame resistant (FR) apparel having excellent electric arc performance. ZOLTEK OX based FR apparel has been UL certified to NFPA 2112 and ASTM F1506 Hazard Risk Category 2.
Acoustical, Heat and Flame Resistant Insulation
ZOLTEK OX fiber can be thermally-bonded into light weight, highloft nonwoven batts and needlepunched to form strong nonwoven products.
Heat and Thermal Protective Apparel
ZOLTEK OX fiber and blends can be made into woven and non-woven materials to produce high performance heat and thermal apparel for the ultimate safeguard from molten metal splatter and radiant heat protection. ZOLTEK OX based heat and thermal materials have been tested to ASTM F955.
