CF4bond angle

HiPerFlon® is a rotary lip seal that features an ID lip that seals dynamically on shaft and with O-ring centered on the OD. They are suitable for medium to high speed with low pressure application. It is widely chosen when the rotary speeds exceed the capabilities of elastomeric seals. With the unique sealing lip construction and excellent self-lubricated features of PTFE compounds, the PTFE rotary lip seal provides superior performance over conventional rubber oil seals. Typical speeds for HiPerFlon® seals are 25 m/s (4925 fpm) and above. PTFE rotary shaft seals are available in a wide variety of PTFE compounds, and utilize common O-ring material choices like fluorocarbon, silicone, nitrile, and EPDM. The use of standard O-ring and PTFE compounds create an easily adaptable solution for all kinds of high-speed applications. Standard HiPerFlon® sizes are precision machined to fit inch-fractional and metric gland geometries, and in-house processing allows custom seal cross sections and diameters to meet any customer request.

Carbon tetrafluoride is colorless and odorless gas with the chemical formula CF4. It is non-flammable gas and is used as a refrigerant in various industries. It is very stable due to the strength of its carbon-fluorine bond. The stable properties are determined by its structure.

Carbon tetrafluoride (CF4) has a central carbon atom surrounded by four fluorine (F) atoms. Carbon has four valence electrons, and fluorine has seven. Hence, carbon requires four more electrons, and fluorine requires one electron to complete its octet. Therefore, carbon bonds with four fluorine atoms through single covalent bonds, resulting in a tetragonal structure. In such a structure, all bonds are equidistant with a bond angle of 109.5°.

The electronegativity of carbon is 2.55, and that of fluorine is 3.98. Carbon is the least electronegative atom and sits at the molecule’s center. Fluorine is the most electronegative atom and attracts the shared electron pair toward itself. The electronegative difference between the two atoms and the ability of fluorine to attract bonding electron pairs make the C-F bond polar. There will be a dipole moment directed from C to F. However, the dipole moments cancel due to tetragonal symmetry, making CF4 nonpolar.
