Detailed introduction to each classification and application scope of PTFE packing

PTFE packing is knitted with high-strength expanded polytetrafluoroethylene and graphite as raw materials. It is a high-quality packing with unique properties and durability. The chemical properties are extremely stable. Except for a few alkali metals in the molten state (such as sodium and potassium), PTFE packing does not react with any substance. PTFE packing has excellent tensile strength and self-lubricating properties. Excellent thermal conductivity, even when the line speed is 20m/s, the packing will not overheat and the equipment can operate for a long time. Today, TOP SEALING will talk about the classifications of PTFE packing and the application scope of each classification.

PTFE packing
PTFE packing is made of pure PTFE dispersion resin. It is first made into raw film, and then twisted and woven into packing. This kind of packing has no other additives and can be widely used in food , pharmaceuticals, papermaking, chemical fiber, etc. have higher cleanliness requirements, as well as valves and pumps with highly corrosive media.

Scope of application: Maximum operating temperature: 260℃; Maximum operating pressure: 2.0MPa; PH value: 0-14.

PTFE filament packing
PTFE filament packing is woven from stretch-reinforced PTFE fibers and then impregnated with PTFE emulsion. This kind of packing can be used in various chemical media, and has certain strength and low friction coefficient. Due to the poor thermal conductivity and large thermal expansion coefficient of PTFE products, this type of packing is often used in rotating parts with low linear speeds (less than 4m/s).

Scope of application: Maximum operating temperature: 260°C Maximum operating pressure: 6.3MPa PH value: 0-14.

Graphite PTFE packing
Graphite PTFE packing is woven from PTFE threads containing graphite particles. It has strong tear strength and high thermal conductivity, and its low friction coefficient makes it stable and long-life.

It is recommended to be used for pump shaft sealing, and can also be used to seal agitators, mixers, autoclaves and centrifugal pumps for water, steam, solvents and other media.

Aramid fiber packing
Aramid fiber packing is woven from aramid fiber impregnated with polytetrafluoroethylene emulsion and treated with lubricant. It has good chemical resistance, high rebound and low cold flow. Aramid packing has excellent high-speed, high-modulus properties (called artificial metal wire).

Therefore, it is resistant to granular crystallizing media and higher temperatures than other types of packing and can be used alone or in combination with other packings. An excellent asbestos replacement product on pump systems.

The most outstanding performance is high strength, good chemical resistance, high rebound, low cold flow, and easy and quick disassembly and assembly. Widely used in various industrial fields.

Due to the reliable performance of PTFE packing, PTFE packing can replace other types of packing in many situations and is suitable for various types of pumps, such as turbine pumps, centrifugal pumps, rotary pumps and reciprocating pumps, etc. In addition , it can also be used for sealing of dryers, mixers, mixers, valves and other equipment. Significant economic benefits. Due to the long service life of PTFE packing, it can reduce your downtime and additional expenses due to frequent replacement of packing, thereby truly reducing your packing usage costs.
