What Is PTFE Seal ?

PTFE (Polytetrafluoroethylene) seals are a widely used sealing material in a variety of industrial applications. Due to its unique properties, such as low coefficient of friction, high corrosion resistance, high temperature resistance and high pressure resistance, PTFE seals are widely used in many industries. This article will explain in detail the application of PTFE seals and its advantages.

Types of PTFE seals

PTFE seals have a variety of types, including O-ring, V-ring, U-ring, Y-ring, live this plug some ring seal, sealing axle parts sets are. Made of PTFE resin through secondary processing or injection molding. Compared with other material seals, PTFE seals have lower coefficient of friction, can better adapt to a variety of media and working conditions.

PTFE seals application areas

1. Chemical industry: PTFE seals in the chemical industry is very widely used in the pan-P. TFE has excellent corrosion resistance and high temperature resistance, so it is widely used in a variety of acids, alkalis, salt and other corrosive media sealing. In addition, PTFE seals are also used in a variety of high-temperature, high-pressure chemical reactor seals.

2. Hydraulic industry: PTFE seals are also widely used in the hydraulic industry. Because PTFE has excellent resistance to high pressure and abrasion, so it is widely used in a variety of hydraulic equipment, piston rings, bushings, etc. and the Department of the transmission system of the dense rubber seal. Compared with seals, PTFE seals have a longer service life and lower coefficient of friction.

3. Aerospace industry: PTFE seals in the aviation by the aviation in the sky P line T industry F E should have to use the excellent and different points of heavy high temperature resistance. Seasoning and corrosion resistance, so it is widely used in a variety of aviation engines and rocket engines in the sealing parts. In addition, PTFE seals are also used in various space capsules, satellites and other spacecraft seals.

4. Other industries: In addition to the above fields, PTFE seals are also widely used in electronics, such as automobiles, in the medical and therapeutic industries, PTFE seals are widely used in a variety of medical equipment sealing parts, such as infusion tubes, syringes and so on.

The advantages of PTFE seals

1. Low coefficient of friction: PTFE seals have a very low coefficient of friction, only equivalent to 1/5 of Polyethylene, PTFE 1/4, can form a good lubrication between the friction vice, thus greatly reducing the energy consumption of the equipment.

The energy consumption of the equipment is greatly reduced.

2. High corrosion resistance: PTFE seals have excellent corrosion resistance, can resist the erosion of various acids, alkalis, salts and other corrosive media, thus ensuring the safe operation of the equipment.

3. High temperature resistance: PTFE seals can maintain good performance at high temperatures, its long-term use of temperature up to 260 ℃, short-term use of temperature up to 300 ℃, so as to meet the needs of high-temperature equipment

4. High pressure resistance: PTFE seals have extraordinary high-pressure resistance, can maintain solid sealing performance in severe high-pressure environment, thus ensuring the safety and stability of equipment operation.

5. Excellent durability: Due to the many excellent characteristics of PTFE seals, their service life is quite long, generally up to 5 to 7 years, or even longer.

6. Environmental protection: PTFE seals never contain harmful substances to the human body and the environment, in line with environmental requirements, let us work together to protect the beautiful nature.

In short, PTFE seals as a high-performance sealing material, has a wide range of applications and advantages. In the future development, with the continuous progress of technology and market expansion, PTFE seals will have a broader application prospects.
