Glass Filled PTFE Filler Content

Selection of the appropriate glass-fiber percentage depends on application requirements. Three stocked compositions balance reinforcement against PTFE's core properties — choose by target strength, wear and chemical-inertness profile.

Key Features

Key Features of Glass Filled PTFE

Peflon glass-filled PTFE combines the structural benefits of glass fiber reinforcement with PTFE's signature chemical and thermal stability — five defining performance attributes.

  • 💪
    Enhanced Strength & Rigidity
    Glass fibers improve tensile strength and rigidity — more resistant to abrasion and deformation.
  • 🛡️
    Improved Abrasion Resistance
    Glass-fiber filler extends service life in wear-intensive applications.
  • 🧪
    Chemical Inertness Maintained
    PTFE's resistance to most chemicals is preserved despite the filler.
  • 🌡️
    High-Temperature Resistance
    Glass filler preserves PTFE's elevated-temperature stability.
  • 📐
    Heat-Distortion Stability
    Improved dimensional stability under high-temperature load.
