The basic properties of Teflon (polytetrafluoroethylene, PTFE) are due to the chemical structure of the polymer, which consists of a double bond of carbon and fluorine.
The size of the fluorine atom allows a uniform, continuous sheath to form around the carbon-carbon bonds to protect them from external attack. As a result, it causes the molecule to have chemical resistance and stability.
Teflon PTFE, on the other hand, retains its properties at very low temperatures. Therefore, it has many applications in important industries such as aerospace and industries that need to work at low temperatures, such as sealing liquid nitrogen tanks at -196 degrees and liquid hydrogen -253.
The main and valuable properties of Teflon (polytetrafluoroethylene, PTFE) that follow its chemical structure are as follows:
- High melting point
- High thermal stability
- Wide temperature range (200 ° C to + 260 ° C)
- Low dynamic friction coefficient
- Constant coefficient / low dielectric discharge
- Low absorption coefficient
- Ability not to erode in the air
- Flame retardant properties
- Excellent non-stick properties
- Biological immobility
- Suitable for use in some refrigeration applications
- Excellent chemical resistance
- Excellent insulation properties
- Teflon gas burning at temperatures above 400 degrees is very toxic and dangerous
- Teflon has low mechanical strength
- At high temperatures, processability is a problem
- Teflon PTFE has a high specific gravity (2.3 times that of polyethylene) which has increased the price of this polymer
Virgin Teflon PTFE is produced and supplied in SHEETS, RODS and TUBES in different .dimensions and sizes
