    20-40um Size PTFE Sheet Material Moulding Processing With Free Flowing Type

    PTFE Resin / PTFE Suspension Powder / 20-40um size / Moulding Processing

    Brief Introduction

    Everflon® PTFE Suspension Powder M series is a white powder with a small particle size. The small particle size of Everflon® PTFE M40&90 helps to minimize voids, even at relatively low molding pressures. Its most unique feature is the irregular, fibrous character of the particles. The fibrous particles promote good capture and uniform distribution of inorganic fillers when they are added to modify the mechanical properties of moldings. It offers an excellent combination of properties that are characteristic of Everflon® fluoroplastic resins.

    Main Processing Way of Everflon PTFE M40

    Everflon® PTFE M usually is processed in two steps: preforming and sintering:

    The powder is first compacted into a preformed shape approximating that of the desired molding. A precise
    heating (sintering) and cooling cycle is then used to consolidate the molding at temperatures above the crystalline melting point of the neat powder.
    The properties of a finished molding are dependent on perform pressure, sintering time and temperature, and cooling rate.

    Properties of Everflon PTFE Resins

    Everflon® PTFE Suspension Powder is preferred for moldings requiring optimum mechanical and electrical properties. Its low bulk density limits the size of moldings from a given mold or press opening. It is often preferred for making filled compounds, especially with metal powders that are difficult to mix because of density differences.

    Main Application of Everflon PTFE M40

    1. Pad.

    2. Rod

    3. Sheet


    Everflon® PTFE Suspension Powders’ preforming is easiest when the resin is uniformly between 21–27 °C (70–80 °F). As temperatures decline below this range, the resin will be increasingly difficult to mold without cracks and problems with condensed moisture. Higher temperatures inhibit flow and promote lumping.

    Storage conditions should be set accordingly. Cleanliness is a critical requirement for successful use of Everflon
    ® PTFE Suspension Powder. The white resin and high sintering temperatures cause even small foreign particles to become visible in finished moldings. Keep resin drums closed and clean. Good housekeeping and careful handling are essential.
