  6. The PTFEO ring has weather resistance and is used for sealing outdoor building materials.

Why do PTFE seals manufacturers use PTFE seals?

PTFE seals manufacturers use ptfe seals due to excellent chemical resistance. Moreover, it has better resistance to strong acids. Such as:

  • Alkalis

  • strong resistance to oxidation
  • and strong dielectric properties
  • Weather resistance
  • wide operating temperature range
  • Similarly, we can use it at a temperature of -180 to +260 degrees.

The main advantages of PTFE seals in chemical or food applications

In applications where irritating chemicals are present; PTFE seals manufacturers use PTFE oil seals. Similarly, leading ptfe seal manufacturing companies offer many different PTFE shaft seal configurations to meet your application needs.

Furthermore, PTFE has good wear resistance, dry running characteristics and many other advantages.

What are the characteristics of non-metal ptfe seals?


Non-metal skeleton PTFE seals can be equipped with O-rings on the outer diameter. The materials of PTFE and O-rings come according to different operating conditions. For instance, we use it in the food industry to ensure equipment can be disassembled for cleaning.

Is the sealing material used in (PTFE) seals the king of plastics?

It is a single copolymer of tetrafluoroethylene. And its performance advantage lies in the stability of chemical media. Similarly, it can be chemically resistant in almost all chemical media.

  • strong acids
  • strong bases
  • oxidants and solvents
  • high temperature resistance and
  • Subsequently, heat resistance has always been well received.

Attention, can work normally in high temperature range. Secondly, the coefficient of friction of PTFE material is low. Furthermore, PTFE seals manufacturers cannot attach many viscous substances to its surface.

How do PTFE seals manufacturers change ptfe seal material?

When pure PTFE seals are not wear-resistant, how to change the practicality of the material? Furthermore, it must come with materials to improve.

Organic materials and graphite can be added to increase wear resistance and longer life. When the improved PTFE seal is suitable for high-speed rotating applications. Simultaneously, the seal adopts a non-spring lip structure to maintain sufficient oil film.

What are the main areas of ptfe seals application?

The oil seal type seals in PTFE seal products are mainly used in:

  • air compressors
  • engines
  • gear boxes
  • Pumps
  • mixers and
  • other precision machinery
  • pharmaceutical and
  • food processing equipment, etc.,

Which technology PTFE seals manufacturers use for molding ptfe seals?


PTFE seals manufacturers mainly include:

  • molding
  • hydraulic pressure
  • pressing, extrusion, spraying
  • Bonding
  • welding and winding.

The first five are processed directly into products with PTFE resin. Subsequently, the latter three are processed into various products using PTFE plastic plates. In addition, there are molding methods such as rolling and thermoforming.

Teflon is a top material in the world today. PTFE seals manufacturers provide many advantages.

such as:

  • colorless
  • wide high and low temperature range resistance
  • chemical corrosion resistance
  • inertness and low friction factor,

Why do PTFE seals manufacturers call ptfe seal plastic king?


It has been widely used as a sealing material and filling material. Moreover, it has become an important material indispensable in all industrial sectors. For instance,

  • automobiles
  • national defense
  • machinery
  • chemical industry
  • electronics
  • construction and other industries.

What is the function of ptfe seals in Teflon plastic pipes?

PTFE seals manufacturers provide strong mechanical properties. Which is conducive to CNC lathe processing. After mastering the forming process, it changes into various shaped product parts.

Generally, it is famous because:

  • saves materials
  • enhances market competitiveness
  • and has excellent corrosion resistance.

Moreover, it has become the main corrosion-resistant material in the petroleum, chemical, textile and other industries.

How to choose the best PTFE seals manufacturers?

PTFE seals manufacturers should guarantee product quality. It should take product quality as the primary task to meet customer requirements. Moreover, his aim should be to reduce costs, reduce waste, and improve work efficiency.

None of his common insulators have smooth surfaces. What makes them corrugated? Similarly,  why are the surfaces of insulators generally corrugated?

The length of the arc climbing will extend. So, at the same effective height, the arc climbing distance increases. Similarly, each ripple can play the role of interrupting the arc.

How do PTFE seals manufacturers make high resistant ptfe seals?

PTFE seals manufacturers make the high-strength wear-resistant sealing ring with modified PTFE. PTFE is one of the materials with excellent corrosion resistance in the world today. It is called “plastic king”. It can be used in any kind of chemical media for a long time.

Subsequently, its production solves many problems in following fields:

  • chemical industry
  • petroleum
  • pharmaceuticals and so on.

Teflon seals, gaskets, and seal gaskets come with suspension polymerized polytetrafluoroethylene resin. Compared with other plastics, PTFE has the characteristics of excellent chemical resistance and temperature resistance. Moreover, PTFE seals manufacturers use it widely as a sealing material.

 high-strength ptfe sealing

      The high-strength sealing comes with ptfe resin. And sintered after cold pressing with a mold. Moreover, it has:

  • excellent corrosion resistance
  • good self-lubricity and
  • non-blocking properties.

Therefore, the products are almost resistant to all chemical media. Moreover, they have the characteristics of wear resistance, pressure resistance, and low coefficient of friction. PTFE seals manufacturers use it in:

  • petroleum
  • chemical metallurgy machinery
  • Transportation
  • Medicine
  • Food
  • electricity and many other fields.

Why do PTFE seals manufacturers use ptfe materials?

PTFE seals manufacturers use PTFE as important sealing materials in many applications. Because of their excellent properties. Such as low friction, high temperature resistance and chemical resistance. However, in high-radiation environments, PTFE will reduce the performance. So, it is difficult to use as a radiation-resistant material.

The impact of radiation to ptfe seals


PTFE seals has the most susceptible to radiation degradation compared to other common plastics.

PTFE exposed to radiation will reduce its tensile strength and elongation. Both high doses of radiation and long exposure time will cause it to fragment. And eventually reduces its strength. The radiation damage threshold of PTFE is 2~7X 104 rads.

PTFE seals manufacturers should also note that the damage threshold of PTFE in vacuum is about ten times higher than that under non-vacuum conditions. Therefore, in the case of ultraviolet radiation, PTFE is very resistant to corrosion. Even if it exposes to sunlight for a long time, PTFE will not degrade or age.

Since ordinary PTFE cannot be used in high-radiation environments. Experienced engineers abroad have tried to use other methods to solve the problem of sensor sealing in high-temperature.


Rubber materials as ptfe seals often rely on the skills of PTFE seals manufacturers. Only expert ptfe seal manufacturing companies can ensure the reliability of the products.  The performance of the product depends not only on the radial pressure the rubber part bears. But also on the friction coefficient of these sealing materials.

The wear of seals under the same radial pressure depends on the friction coefficient of the seal material. The friction coefficient is small. The frictional heat generation effect is small. The amount of wear is small. And the service life of the seal is long; vice versa.
