SSTFE is an abbreviation for semi-solid tetrafluoroethylene, a partially foamed TFE fluoropolymer insulation that lowers the dielectric constant for high-frequency cable.
SSTFE stands for semi-solid tetrafluoroethylene, a partially foamed form of TFE, the fluoropolymer family that includes PTFE. By incorporating air through partial foaming, the material gains a lower effective dielectric constant than solid TFE, improving high-frequency signal performance, while retaining the outstanding heat and chemical resistance of fluoropolymers. This combines premier high-temperature insulation with reduced dielectric constant for demanding high-frequency cable.
Because TFE fluoropolymers already offer excellent dielectric properties and thermal performance, a semi-solid form like SSTFE further enhances signal performance through its lower dielectric constant. This suits it to high-frequency cable that must also withstand heat and chemicals.
In commercial and industrial communication, semi-solid fluoropolymer insulation like SSTFE supports high-performance, high-temperature signal cable. Recognizing the designation helps in interpreting specifications.
