It is designed to have both high tensile strength and flexibility simultaneously for braiding continuous filament carbon fiber having high thermal conductivity and low coefficient of friction in a unique method of DONGSUH. Such braiding feature allows for convenient use in any size of the device guaranteeing the most optimal flexibility unlike other conventional carbon packings which are to stress only high strength. DONGSUH ALS910C prevents the air gas or liquid from being leaked out or penetrated into the packing inside since the high purity inorganic agent for preventing penetration is spread inside or outside packing with the heatresistant lubricant. The special braid technology available only by DONGSUH prevents such penetration preventing agent or heat-resistant lubricant from being leaked out. The surface will minimize the stem damage caused by friction and high purity graphite and molybdenum-based anti corrosion agent have been used to prevent the stem from being corroded so that the packing performance for something like friction and anti corrosion was much improved. For valve type, if you use it with DONGSUH ALS350 as End Ring, you can get the better sealing effect.
