Features
- Low Co-efficient of friction
- Fluorocarbon polymers have the lowest co-efficient of friction of all solids and possess an unique self lubricating ability. PTFE's friction co-efficient is between 0.5 and 0.8
- Because the static friction and dynamic friction are similar PTFE does not exhibit a stick / slip type of motion which makes PTFE particularly suitable for non lubricated slide bearing applications.
- Chemically inert
- PTFE is considered to be inert towards nearly all known chemicals and it is insoluble in all solvents. The only chemicals known to attack PTFE are molten alkali metals and certain halogenated chemicals at high temperatures and pressures.
- Temperature resistance
- Fluorocarbon Polymers are flame retardent and exhibit excellent thermal stability. Although PTFE is a thermoplastic it does not melt and can be used in temperatures ranging from -100 Celsius to +260 Celsius. Unlike many other materials it will not harden and become brittle when subjected to such extremes in temperature.
- Zero moisture absorption
- PTFE has the lowest moisture absorption rate of all plastics. As it's moisture absorption rate is negligible (less than 0.1%)
- there is no swelling of components when immersed in fluids for long periods of time.
- Electrical properties
- PTFE has excellent electrical properties. It's dielectric strength is approx. 24,000 volts per mm and it remains unchanged even at high temperatures and decreases only according to the thickness of material and the increase of electrical frequency. PTFE's ability to withstand high temperatures without becoming brittle makes it particularly useful as insulation sleeving in a wide variety of applications.
- Weather resistance
- PTFE is completely indifferent to ultra violet light and outdoor weathering. Experimental samples exposed to the harshest weather conditions for many years are completely unchanged.
- Non stick
- PTFE surfaces are highly anti-adhesive. Even modern super glues will not permanently adhere to an untreated PTFE surface.
- Non toxic
- PTFE is non toxic and can be used in contact with foods. However, it must be noted the same cannot be said for filled PTFE, owing to the toxicity of some filling compounds c. g. heavy metals and their compounds.
