Zeus Drawn Fiber Monofilament Essentials: Deciding Which Is Right For You – PVDF and Fluorine Chemistry (Part 1 of 2)

Zeus drawn fibers are performance fibers and offer enhanced mechanical attributes beyond those of ordinary extruded monofilaments. PVDF serves as a representative fluoropolymer illustrating how fluorine can often improve fiber properties. This presentation introduces fluorine chemistry and discusses advantages of drawing down fibers combined with the benefits of using fluoropolymers.

Zeus drawn fibers are performance fibers and are a special case of monofilaments. They can be used in a variety of applications ranging from hose and catheter braiding, weaves, guitar strings, racquet strings, to name but a few. Our drawn fiber benefits from the additional step of draw-down post-extrusion producing. In this presentation, we describe how this process affects polymer chains within the fiber leading to enhanced mechanical properties versus simple extruded monofilament.

Zeus produces drawn fiber monofilament in multiple resins including PVDF, FEP, ETFE, PFA, ECTFE, and PEEK. Of particular interest is that many of these drawn fibers are created from fluoropolymer resins. We describe how one such example, PVDF, serves as a kind of "gateway" polymer to illustrate how the incorporation of fluorine affects material attributes, often resulting in preferred chemical and mechanical properties. While the simplified representation of PVDF monomer on paper appears straightforward, its three-dimensional structure is far more complex and can mask polymer and material attributes. We discuss fluorine's effects upon the three-dimensional polymer chain structure and how it can even produce differences in electrical properties.

With such possibilities, Zeus can often control and customize their drawn fiber monofilament to suit specific applications. Properties such as tensile strength, elongation, or tensile modulus can be modified within limits to accommodate demanding working conditions and specialty uses. This presentation provides a limited overview of drawn fiber characteristics, a brief primer on fluorine chemistry as it relates to fluoropolymers, and a short survey of several fiber properties of popular interest.

Key Take-Aways

  • Zeus drawn fiber monofilaments are performance fibers designed for difficult or harsh operating environments
  • Drawn fibers benefit from the combination of extrusion followed by draw-down to enhance their mechanical properties
