Fixed Competitive Price Carbon Fiber Packing Impregnated with PTFE for Poland Manufacturers

Diagonal braided to form a dense but pliable packing, each carbon fiber is pre-impregnated with PTFE, and re-impregnated during square braided. It is premium service packing for media of weak chemical corrosion and grains of particles exit.

Technical Data Sheet

 Application Area

Resist all the strong corrosive media and media with a few crystal particles with the exception of the strong oxidizing agent polonium, chiefly used for the sealing of the centrifugal pump, column pump, mixer and valves.

Modular back-ups, MB profile, are specifically designed to compliment the PolyPak profiles. To help make the selection and ordering of the correct part number for the MB profile easy and efficient, the part numbering system used is very similar to that of the PolyPak. By formulating high modulus blends of Molythane (4617) and PolyMyte (4652), Parker has ensured that MB back-ups can be used with either type of base sealing material while maintaining the expected temperature range and fluid compatibility. The robust design ensures pressure ratings up to 10,000 psi are met.

Back-up rings are the most common anti-extrusion devices in dynamic sealing. They provide simple solutions to safely increase system pressure or solve an existing seal extrusion problem. Back-up rings function by positioning a more robust material adjacent to the extrusion gap, taking the seal’s place and providing a barrier against high pressures. Back-ups can be used to offset the reduced pressure rating effects of wear rings or to improve seal life at increased pressures. They can also be used to protect seals against pressure spikes, or to ensure seal performance at higher temperatures.
