Enflon® Filled PTFE

Enflo Filled PTFE productsIn most situations, PTFE is an ideal choice for a wide range of applications. There are occasions, however, when additional “fillers” such as graphite, carbon, glass, bronze, and other materials are added to enhance PTFE products for use in a specific application. Generally speaking, these “Filled PTFEs” maintain their original chemical and thermal resistance characteristics, while also exhibiting improved strength, stability, and/or durability.

Enflon® Compounds

Enflo’s Enflon® brand of Filled PTFE products are blended in our plant to offer a wide variety of improved material characteristics and properties. Enflo offers the following standard fills, and we can duplicate most PTFE blends.:

Glass Fiber

Milled glass fibers have the least effect on chemical and electrical properties and add greatly to the mechanical properties of unfilled PTFE. The addition of glass improves compressive properties by as much as 40% and improves wear resistance greatly. These compounds resist acids and oxidation, but can be attacked by alkalis.

  • ENFLON 101 – 5% Glass Fiber
  • ENFLON 102 – 10% Glass Fiber
  • ENFLON 103 – 15% Glass Fiber
  • ENFLON 104 – 20% Glass Fiber
  • ENFLON 105 – 25% Glass Fiber
  • ENFLON 106 – 30% Glass Fiber

Graphite

Graphite offers improved chemical resistance to corrosive environments and exhibits good initial wear and rubbing/sliding characteristics in dry and water applications. Graphite is commonly blended with carbon and PTFE.

  • ENFLON 110 – 5% Graphite
  • ENFLON 111 – 10% Graphite
  • ENFLON 112 – 15% Graphite
  • ENFLON 113 – 20% Graphite
  • ENFLON 114 – 25% Graphite

Bronze

This filler has better wear, creep resistance, and higher thermal conductivity than glass fiber with PTFE. The compound is easily machined, but has poor chemical resistance in the presence of acids and alkali. Useful in applications which undergo high mechanical loads or high-speed rubbing contacts where the bronze filler supplies the strength and conductivity to carry away excess, unwanted heat.

  • ENFLON 115 – 25% Bronze
  • ENFLON 116 – 40% Bronze
  • ENFLON 118 – 60% Bronze

Carbon

Carbon has good chemical resistance to corrosive environments. It exhibits good initial wear and rubbing or sliding contact characteristics, both dry and water applications. It is frequently used in piston rings to reduce cylinder wall wear by entrapping abrasive foreign particles in their relatively soft surfaces.

  • ENFLON 130 – 5% Carbon
  • ENFLON 131 – 10% Carbon
  • ENFLON 132 – 15% Carbon
  • ENFLON 133 – 20% Carbon
  • ENFLON 134 – 25% Carbon

Contact us for a customized blend.

Molybdenum Disulfide

This filler is used frequently in combination with others to increase surface hardness, stiffness, and to reduce the starting coefficient of friction and steady-state wear. Its effect on electrical and chemical properties is negligible.

  • ENFLON 127 – 5% Molybdenum Disulfide

Colors

Colors are often added to PTFE for product identification, visibility, and/or branding.

  • ENFLON 191 – Red
  • ENFLON 192 – Orange
  • ENFLON 193 – Yellow
  • ENFLON 194 – Green
  • ENFLON 195 – Blue
  • ENFLON 196 – Purple
  • ENFLON 197 – Brown
  • ENFLON 198 – Grey
  • ENFLON 199 – Black
