PTFE (Polytetrafluoroethylene)

Features:
  • Polytetrafluoroethylene (PTFE), or known as Teflon is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. PTFE belongs to the group of highly chemically resistant fluorothermoplastics. Due to its high molecular weight, highly chemically resistant PTFE cannot be processed by melting, but only by pressing and sintering to create semi-finished products. PTFE is the most commonly used and important fluoropolymer with the most extensive fields of application: chemical plant engineering, food and pharmaceutical technology. PTFE is preferred for sliding applications with exposure to extreme chemical stress.
  • Stock Shape / Size Range : Plate (Thickness: 1mm - 100mm) / Rod (Dia: 4mm - 160mm)

Preferred Fields:
Bushings & bearings, chemical processing components, electrical components, gaskets, pump & valve components, seals, valve seats, wear pads, and food industry appliation.
 

Characteristics:

  • Very high crystallinity, highest density of all polymers
  • Very tough down to low temperatures
  • Extremely high resistance to chemicals, also to oxidizing acids
  • Hydrolysis-resistant
  • Very low moisture absorption
  • High thermal stability, low dimensional stability at temperature
  • Anti-adhesive properties, very good  sliding properties, no stick-slip behaviour
  • High resistance to UV radiation, high thermal expansion
  • Minimal dissipation factor, good electrical insulation properties
  • Inherently flame resistant, self-extinguishing
