15 % Graphite PTFE

SSP Manufacturing, Inc. provides a wide range of seals made from 15% glass-Teflon material. The glass filled Teflon is basically a PTFE material reinforced with 15% glass fiber. This reinforcement improves material characteristics. 15% glass filled PTFE seals are ideal for various complex industrial applications due to their reinforced composition.

Benefits of 15% glass filled Teflon Seals

The following are a few of the benefits of using glass filled PTFE seals for industrial applications:

  • Glass filled PTFE provides excellent thermal stability across wide temperature ranges.
  • Glass filled Teflon has excellent durability, as well as compressive strength when compared to regular PTFE. This helps improve the shelf life of our seals.
  • Glass filled Teflon seals provide excellent chemical resistance. As PTFE is a chemically inert material at elevated temperatures, it makes them ideal for all industrial solvents, as well as chemicals. This property makes our seals ideal for a wide range of industrial applications involving chemicals. These seals are suited for food and pharmaceutical industries, and satisfy FDA requirements. The seals are not recommended for use with strong bases and hydrofluoric acid.
  • 15% glass fiber filled Teflon material strongly resists permanent and load deformation, which makes our seals ideal for high load applications.
  • Glass filled PTFE materials are not affected by daily wear and tear, and remain largely unaffected by Ultra Violet (UV) light.
