Flexible Graphite Yarn

Flexible Graphite Yarn is made of Pure Flexible Graphite Tape. It is twisted and treated by special process and treatment. During the process, the graphite is reinforced with threads of cotton or other materials.   It is suitable for sealing under different media, circumstances, temperature, and pressure.  CeramSource graphite products offer unparalleled service in industrial environments where high temperatures and crushing pressure cause constant failure of conventional packings.  CeramSource packing is to give users the greatest return on initial investment in terms of leakage control, service life, and dependable cost saving product.

Why Graphite?
Graphite has several advantages over other materials. It is resistant to thermal shock. It is the only material in which mechanical properties increase with temperature. It has a low CTE for geometrical stability. It is easily machined. It does not melt but sublimes at very high temperature (3,400ºC), and finally, its density is lower (five times less than copper) which means lighter electrodes. Graphite removes material better than copper or copper-tungsten while wearing slower. The wear rate tends to diminish as the discharge increases, unlike copper, whose wear increases at higher currents. Therefore, graphite is suited for the machining of large electrodes since working with a high current intensity provides decreased roughing time.

Although graphite is prone to abnormal discharge, this can be eliminated through quality flushing, and lowering the intensity of discharge during negative polarity machining. However, as a result of this tradeoff, machining tungsten carbides is more difficult than with copper-tungsten electrodes. Also, since graphite is a ceramic, it is sensitive to mechanical shock, and consequently must be handled and machined with care.
