Ceramic-yarn Sleeve: CERAC-SL
The ceramic-yarn sleeve, CERAC-SL, is an ultrahigh-temperature-resistant sleeve that is made of cylindrically braided ultrahigh-temperature-resistant alumina filament fiber. CERAC-SL shows flexibility at high temperature nearly equal to that at normal temperature. Also, it maintains satisfactory tensile strength even at high temperature. It hardly shrinks or absorbs moisture. Its normal usage temperature is 1000℃ with an upper usage temperature limit of 1200℃. It is ideally used in applications such as the following: insulating or protecting thermocouples and heaters; insulating wire around furnaces; and protecting hoses, tubes, and electric wire from sparks in ironworks, aluminum refineries, etc.
