PTFE MACHINING
Polytetrafluoroethylene (PTFE) is a polymer with properties that are impossible to find in any other plastic material.
Its most peculiar characteristics include:
- Exceptional chemical resistance
- High range of service temperatures and very low thermal conductivity
- Good electrical insulation
- Minimal moisture absorption
- Excellent aging resistance
- Low coefficient of friction
PTFE is available both virgin and filled. The most important additives are:
- Glass fiber: improved wear resistance and chemical resistance (except to alkalis and hydrofluoric acid)
- Carbon: for enhanced thermal conductivity and wear resistance
- Graphite: for improved wear resistance
- Molybdenum disulfide: for increased sliding properties and decreased friction
- Bronze: for improved compression strength and wear resistance but reduced chemical resistance
- Stainless steel: for improved compression strength, high thermal conductivity, chemical resistance, and absence of electrostatic charges
- Carbon fiber: for improved thermal dimensional stability and resistance to abrasion
