Kynol Fiber Gland Packing

Kynol fiber, or phenolic fiber, is a high-performance fiber. Manufacturers create it from phenolic resin using spinning and curing cross-linking processes. Scientists developed Kynol fiber in 1968. It was for U.S. space tech research. It is now used in high flame-resistant industries and as an asbestos substitute.

The phenolic fiber does not melt or burn in a flame at 2500℃. It has good thermal insulation performance and excellent corrosion resistance. This fiber makes the packing. The PROIM process and an advanced, high-speed braiding machine process it. It is a kind of sealing packing with excellent performance. It is best for reciprocating or rotating pumps. The conditions are high speed, high pressure, and corrosive, particle-laden media.

Kynol fiber gland packing for pump made of phenolic yarns, lubricated with PTFE, has an excellent charge-to-gain percentage. It is one of the best options for the pulp and paper, sweets, and liquor sectors. These industries need packing that can withstand granular and coarse applications. It provides high durability. It can resist a chemical strike without harming the shaft.

Features

Kynol fibers have an exceptional level of flame resistance. They only carbonize when burned. They produce little smoke and few toxic gases.

Heat resistance: They do not melt at high temperatures. They have good thermal stability. The long-term heat resistance temperature range is 150–250 °C.

Chemical stability: They resist many organic solvents and acids. They require significant time to dissolve or corrode.

The kynol fiber gland packing are lightweight. They bond well with light resins or rubber and also have excellent electrical insulation and friction material properties.
