PA1003 Graphite packing reinforced with carbon fiber

The packing is braided from low sulphur expanded graphite yarns which are reinforced with high strength, high modulus carbon fiber continuous filament in each single yarn. It is then impregnated in mixture of graphite powder, molybdenum disulfide and PTFE emulsion, and processed with high temperature curing treatment. The packing shows excellent chemical stability and thermal conductivity, and high intensity.

PA1016 Graphite packing with carbon fiber corners

The packing is diagonally braided from expanded flexible graphite, with high quality carbon fiber reinforced at the corners. This kind of structure makes it three times more resistant against extrusion than PA1000. It also increases the compressive property of the packing.

Application:

PA1003 is particularly applicable to rotary pumps and reciprocating pumps with mediums of strong chemical corrosive, or containing particles.

PA1016 is widely used for both static and dynamic sealing applications. Particularly suitable for valves, pumps, expansion joints, mixers and agitators in high temperature and high pressure environments in paper mills, power stations and chemical plants etc.
