Polytetrafluoroethylene (PTFE), often dubbed as "The King of Plastics," reigns supreme in the fluorine chemical industry. PTFE, famously known by the brand name Teflon, stands out as a remarkable fluoropolymer renowned for its exceptional properties. From its high heat resistance to its unparalleled chemical inertness, PTFE has carved a niche for itself in a wide array of industrial applications, solidifying its throne in the realm of plastics.
Unmatched Performance Properties
PTFE's unparalleled performance characteristics stem from its molecular structure formed by carbon-fluorine bonds. PTFE has a series of advantages including:
- High temperature resistance (can be used for a long time in the temperature range of 200~260°C).
- Low temperature resistance (can be used for a long time below -100 °C).
- Corrosion resistance (extremely high chemical inertness).
- Weather resistance (extremely high resistance to atmospheric aging).
- High lubricity (extremely low friction coefficient).
- Non-adhesion (extremely low surface tension, not easy to adhere).
- Good human compatibility (good physiological inertness and non-toxic).
- Good electrical insulation (high insulation, not affected by temperature and humidity).
Fluoropolymer with the Largest Market Size
After decades of rapid development, PTFE has become the fluororesin with the largest output. In 2017, the global fluoropolymer market size reached US$9.2 billion, with a total production capacity of approximately 490,000 tons/year, of which PTFE was approximately 280,000 tons and a total output of 190,000 tons, making it the fluoropolymer with the largest output and the fastest consumption growth.
In 2017, the global polytetrafluoroethylene market size was US$2.87 billion, and the compound annual growth rate from 2018 to 2025 is expected to be 5.2%. It is expected that the demand from various application industries (especially the electrical and electronics industries) will continue to grow, which will continue to drive the development of the PTFE market.

Expansion from Traditional to Emerging Applications
After the 1970s, PTFE began to rapidly penetrate downstream application scenarios such as chemical, mechanical, electronic, medical materials and textile industries with its corrosion resistance, weather resistance, self-lubrication and excellent insulation properties. With the substantial growth of industries such as electronics, automobiles, and aerospace since the 1990s, the consumer demand for PTFE has been further driven to a large extent. Next, let us explore how PTFE can support the arrival of the 5G era.
PTFE Entering the 5G Field
The 5G era brings with it unprecedented requirements for materials that support high-frequency transmission, particularly those with low dielectric constants and minimal dielectric loss. PTFE, with one of the lowest dielectric constants among organic materials, is emerging as a key contender for meeting these demands.
5G requires the dielectric constant of low dielectric materials to be between 2.8 and 3.2. The main low dielectric constant materials are PTFE, PPO, LCP and PI (or MPI). Among them, PTFE, as one of the materials with the lowest dielectric constant (Dk=2.1) among organic materials, will be widely used in base station filters, high-frequency and high-speed PCB/FPC, 5G chip processes, high-frequency connectors, cables and other fields in the 5G communication field.
