Characteristics of aramid packing

Apr 23, 2019

The aramid packing is woven from aramid fiber impregnated polytetrafluoroethylene emulsion and agent. Some have chemical resistance, high rebound, and low cold flow. It has excellent high-speed, high-modulus properties (known as man-made metal wires). It has three times the strength of the wire and is five times lighter than the wire. Therefore, it can be used alone or in combination with other packings, as opposed to other types of packing, against particulate crystalline media and higher temperatures. It is a good asbestos replacement on the pump.
The aramid fiber braided packing is made of aramid fiber with a degree and high modulus as the main material, impregnated with PTFE and special agent, and woven into a rope-like or ring-shaped sealing product. The filler has excellent properties and wear resistance, and is particularly suitable for fluid-liquid mixing fluid devices. Suitable for mediums such as steam, acid and alkali. It is applied to the sealing of multi-particle and high-wear parts such as ash pump, reaction kettle and slurry pump.
