Braided Gland Rope
Radiant is Manufacturer of PTFE braided Packing Rope. A clear understanding of the differences between the various forms of PTFE braided packing will enable a selection of reliable sealing for the pump or valve. Of the many forms of PTFE braided packing, the right choice takes advantage of its strengths and minimizes its limitations. A few unique properties of PTFE make it an excellent ingredient for braided packings: Excellent chemical resistance. A major reason for using PTFE in packing materials is that it is unaffected by a wide variety of aggressive fluids, including very strong acids, bases, and solvents. Perhaps most important is PTFE’s ability to withstand strong oxidizers such as nitric acid, chlorine dioxide, high concentration sulfuric acid (Oleum), and others. PTFE may be the only practical option for applications involving these media. Low coefficient of friction in contact with most surfaces. The non-wetting, slippery, low friction behavior of PTFE can help to reduce power consumption and generation of heat at the packing-shaft interface.
Features:
Pure PTFE fiber packing is a braided packing made of PTFE yarn without soaking any PTFE dispersion and lubrication but with greatly enhanced ability to seal high speed shafts with the addition of inactive and heat-resisting agents. It is recommended for chemical engineering, foodstuff, pharmaceuticals where contamination is not allowed. It can also be applied to seal all chemicals except molten alkali metals.

Asbestos Impregnated PTFE Braided packing Rope is braided into packing, made of asbestos yarn and impregnated with PTFE. It has better effect of sealing. It is used for all rotating and reciprocating pumps, mixers and valves sealing against hot and cold water, caustics, mild acids, difficult chemicals, air, gases, steam, solvents, oil and most main applications.
