MI-3906 is a high performance Combination Packing of Aramid Fiber Yarn at the corners & Expanded PTFE Graphite solid yarn at the faces having core of Aramid yarn. The Aramid yarn is impregnated with highly anti-frictional Fluoropolymer dispersion and special break-in-lubricant. This packing is ideal for services where chemical resistance, high strength & sliding properties are essential. The special Aramid Fiber at the corners enhances pressure & extrusion resistance of the packing even in reciprocating equipments such as plunger pumps. The PTFE Graphite Yarns at the faces facilitates low friction for shafts due to its inherent characteristic of heat dissipation and ensures cooler shaft run.
Also Available : This packing can also be made available with a core of Pure PTFE Graphite Yarn instead of Aramid Yarn Core for more resiliency and cost effectiveness.
