Definition: PTFE was discovered by chance in 1938 by Roy Plunkett, who was working at Kinetic Chemicals at the time. PTFE (Polytetrafluoroethylene) is a synthetic fluoropolymer with a wide range of applications. The best known commercial brand based on PTFE is Teflon, manufactured by DuPont.
Application Area: It is widely used in the production of cables used in aviation and computer technologies due to its excellent dielectric properties, in fuel and hydraulic lines due to its very low fluid resistance, in the production of seals and packings used in shafts, pumps and valves due to its low friction resistance, and in the production of gear-like parts due to its non-stick properties.

| GENERAL PROPERTIES OF PTFE | ||||
| Heat | Flame Resistance | Friction and Wear | ||
| PTFE is a material that maintains its properties even when exposed to temperatures beyond the heat limits of almost all plastics and elastomers. Depending on end-use criteria, the continuous service temperature of PTFE is 260 0 C. It can withstand higher temperatures for short-term use. | PTFE has excellent high temperature and flame resistance, high melting and decomposition temperature. PTFE's flame propagation characteristics such as heat release and flame generation rate are very low. | PTFE is a material with the lowest coefficient of friction among solid materials. Wear resistance can be adjusted to suit the intended use by using glass fiber, carbon or graphite. | ||
| Environmental Pollution | Adhesion, Separation | Low Temperature Operation | ||
| PTFE is chemically pure and inactive. It does not contain additives that contaminate process fluids such as oil, stabilizing additives, plastic additives or antioxidants. | PTFE has extremely low surface energy in the solid state, providing an excellent adhesive and non-wet environment. | PTFE maintains its excellent properties even at temperatures well below freezing. The impact resistance of PTFE at these low temperatures exceeds the impact resistance of most other polymers. | ||
| Corrosion | Service Life | Light Stability | ||
| PTFE has excellent chemical resistance. Over a wide temperature range, PTFE is resistant to most harsh organic and inorganic chemicals, acids and solvents. | PTFE retains its properties perfectly even in the presence of oil, solvent, UV light, oxidants, other environmental agents and high temperatures. It is resistant to discoloration and brittleness. | PTFE has the lowest refractive index. There is no change in appearance when exposed to ultraviolet and infrared light. | ||
| Dielectric | Biodegradation | Moisture | ||
| PTFE has good dielectric strength and dielectric constant. The loss factor is low. In terms of stability and level of dielectric property under wide environmental conditions, PTFE is better than most materials. | In its pure form, PTFE is inactive against microbiological and enzyme attacks because it does not provide microorganisms with nutrients or a porous environment for their growth. | PTFE is completely resistant to chemical reactions. It is a good barrier to water. Even if it is left in water for a long time, the chemical, physical and dimensional properties of PTFE remain unchanged. | ||
