ePTFE Yarn
For Compression Packing Braiding

The expansion process for PTFE creates a micro-structure of interconnected PTFE nodules and fibrils, creating an extremely strong micro-structure that is considerably higher in tensile strength. This strength results in far more resistance to cold flow, which then decreases creep relaxation when compared to traditional non-expanded fiber. The resulting fiber is still 100% PTFE and, therefore, maintains all the inert properties of PTFE with a pH range of 0-14 with few exceptions. It has low surface free energy (18.5 dynes/cm2 or .00027 psi) with excellent self-lubricating values and can withstand continuous service in temperatures from -200º C to 260º C (-328º F to 500º F).

Specification:

  • Specification: 1.5g/m 2g/m 2.5g/m 3g/m 3.5g/m 5g/m

 

For Compression Packing Braiding

ePTFE / Graphite creates a compression packing fiber that combines the properties of each material. The graphite content creates a fiber that is thermally stable and has a high thermal conductivity. The ePTFE fiber provides strength and high conformability and enhances the ability of the packing to be easily installed and removed. The combination of the two materials creates a packing with a low coefficient of friction, good dimensional stability, and high resistance to chemicals with a pH range of 0-14. ePTFE / Graphite fibers are only limited by temperature and can give continuous service up to 288°C (550°F). These yarns are generally used in applications where surface speed is under 20 m/s (4000 FPM).

Compression Packing
Pure PTFE Packing – Flexible and chemically inert. PTFE-Impregnated Packing (e.g., with graphite or aramid fibers) for enhanced strength and temperature resistance. Expanded PTFE (ePTFE) Packing – Improved conformability and sealing performance.
ePTFE Joint Gasketing
ePTFE is available in sheet, tape or cord (joint sealant) form. The tape and cord forms are solid form-in-place products.

Cold flow is most effectively reduced in expanded PTFE gaskets (ePTFE) by physically altering the PTFE microstructure. 


The ePTFE microstructure is a network of interconnected nodes and fibrils that increases the tensile strength of the material, decreases the density of the material and increases the compressibility of the material. Because of the high compressibility, ePTFE gaskets conform well to surface irregularities. Unlike virgin and filled PTFE gaskets, ePTFE materials are more easily applied in glass-lined steel, fragile plastic flanges and other fragile flanges. In addition, ePTFE is available in sheet, tape or cord (joint sealant) form. The tape and cord forms are solid form-in-place products.

Materials are more easily applied in glass-lined steel, fragile plastic flanges and other fragile flanges.
