    Proprietary material designed to enable increased performance in High Pressure High Temperature (HPHT) applications. Tetrex® 5000 is a high creep-resistant PEEK material which provides outstanding chemical resistance to acids, caustics, sour gas, and hydrocarbons. The Tetrex® 5000 material is ideal for improving seal performance in demanding Oil & Gas drilling and completion applications including geothermal, steamflood/SAGD, high H2S environments, and applications requiring high temperature performance.

    TETREX® 5000 Temperature Test


    The photo shows FOGT’s Tetrex® 5000 (on left) and Virgin PEEK (on right) after exposure to 750° F for 10 minutes on a hot plate. Tetrex® 5000 did not melt and did not show distortion of the material, unlike Virgin PEEK which showed significant damage to the material.

    Tetrex 5000 Creep Properties at 200° C


    Creep testing was conducted using a tensile specimen at 10 MPA at 200° C. Tetrex® 5000 recorded the lowest creep rate among samples tested. 

    Tetrex® 5000 Extrusion Performance

    Tetrex 5000 Extrusion Performance

    To evaluate extrusion resistance on backup rings, a standard backup ring was tested under high temperature and pressure. Tetrex® 5000 showed higher extrusion resistance than Virgin PEEK and PAEK-HT materials.

    The results showed Tetrex® 5000
    outperformed PAEK and Virgin PEEK..
