CONSTRUCTION
Style 2017 packing is an interlock braid of Teadit's EG2 PTFE/graphite yarn, reinforced with high strength aramid yarns corners. EG2 is formed from expanded PTFE in which fine particles of graphite have been encapusulated. The resulting packing provides good chemical resistance and heat dissipation plus anti-extrusion strength.
APPLICATION/SERVICE
Style 2017 packing can handle a broad range of chemicals in the 3-11 pH range. It is used in papermill stock pumps, agitators, or any service where high strength and good lubricating qualities are needed.
