Fluoropolymer properties are built around the very strong Carbon Fluorine bond.
Hydrophobic - neither water nor water-containing substances wet fluoropolymers Very Low coefficient of friction of any solid.
Very low working temperature – PTFE and other fluoropolymers maintain high strength, toughness and self-lubrication at low temperatures down to 5K.
Inert / Non re-activity - Its high corrosion resistance makes PTFE useful in laboratory environments, where it is used for lining containers, as a coating for magnetic stirrers, and as tubing for highly corrosive chemicals such as hydrofluoric acid, which will dissolve glass containers.
UV resistance leads to long working life in outside environment. Electrical insulation allowing thin coating on wire with wide working temperature range. Will burn when exposed to flame but generally self-extinguish when flame removed.
It can be stretched to contain small pores of varying sizes and is then placed between fabric layers to make a waterproof, breathable fabric in outdoor apparel. Powdered PTFE is used in pyrotechnic compositions as an oxidizer with powdered metals such as aluminium and magnesium. Upon ignition, these mixtures release large amounts of heat. Fibrillation for use as drip resistance reinforcement of other polymers. Stretching without changing diameter - plumbers tape and gaskets
Other Fluoropolymers (FEP/PFA/MFA/ETFE/ECTFE/PVDF/EFEP…)
Many variants with various additional properties
- Excellent visible spectrum light transmission.
- Cut resistance making ideal for high vibration applications like helicopter wiring
- Mold release films for epoxy in a carbon fibre/epoxy composite laminate
