Graphite material molding is mainly to improve the density of the mixture powder, so that aggregate and binder close contact, in order to obtain a certain size, morphology and processing margin of green.
tape. The most common form is an ePTFE impregnated with graphite to increase its thermal conductivity and speed rating. ePTFE braids are less sensitive to heat buildup than PTFE fiber • Sealing Sense When should I use braided PTFE packing, and in what form?

treated with graphite to withstand caustic liquors, including caustic potash, soda, lime, ammonia and sulphides. An ideal packing for paper mill application. pH 4 - 12. Non-metalic asbestos lubricated and graphited packing for high pressure saturated super heated steam conforming to IS Specification 4687 & DGS&D Specification.
Graphite is an extremely good thermal conductor and as such the packing dissipates heat away from the body leading to a longer life of the packing. These rimgs are also manufactured for nuclear applications with slightly improved chemical properties. These packing's are stable even under exposure to high doses of nuclear radiation.
The packing industry responded by experimenting with exotic fiber materials such as PTFE yarns, graphite yarns, carbon yarns, and GFO® yarns to create packing that not only complied with more stringent water usage standards, but was also able to withstand higher temperatures, faster shaft speeds, and wider pH ranges than ever before.

1140GFO ® possesses the most efficient set of physical characteristics to remain, to this day, the #1 choice as universal mill compression packing. We produce it from high tensile modulus PTFE (polytetrafluoroethylene) yarn into which a high percentage of micronized graphite and a small percentage of dimethylsiloxane (silicone lubricant) is added.
Each strand is lubricated with a special vegetable and marine oil and graphite. When the braiding is finished, the surface of the packing is graphite coated so that the packing does not wick because of the lubricant. Sizes: 1/8" to 1" square in increments of 1/16" standard, consult factory for sizes larger than 1".
