PB10000 SERIES

Mineral PTFE

Mineral-filled PTFE materials are usually referring to mica-filled PTFE compounds. However, there are other mineral fillers added to PTFE compounds to produce specially applications.

  • Calcium fluoride (CaF2) can replace glass in end-uses where glass is attacked by chemicals.
  • Alumina (Al2O3) is an excellent electrical insulator, which also improves the mechanical properties of the compound for use in high voltage components.
  • Mica (Phyllosilicate) has a plate-like structure and its particles tend to orient themselves perpendicularly to the molding direction. This results in a significant reduction in shrinkage and the coefficient of thermal expansion in the direction of orientation. However, physical properties of the compounds are severely lowered; therefore, mica compounds are recommended for compressive applications only.
