GORE® ePTFE Fiber and Filament
GORE® ePTFE Fiber and Filament offer advanced performance in demanding applications through revolutionary fiber technology.
Exceptional Performance in Challenging Environments
GORE® ePTFE Fibers and Filaments are engineered to offer exceptional performance in a range of challenging environments. Designed to meet the highest industry standards, these fibers and filaments are versatile, tough and abrasion resistant while maintaining tensile strength.
Tensile strength, modulus (stiffness), density, surface texture, additive capability such as color and other required attributes are designed into GORE® Fibers and Filaments to provide unique solutions with one single fiber material. The fiber can be sewn, knitted or woven into various structures, and combined with other yarn material to achieve the desired properties of the finished product.
Unique in the industry
GORE Fibers and Filaments are made from proprietary expanded polytetrafluoroethylene (ePTFE) with a microporous structure and specific engineered physical properties to meet a wide range of applications. They are a true monofilament—a round fiber with precise diameter control to enable precision weaving.
Tensile strength, modulus (stiffness), density, surface texture, additive capability such as color and other required attributes can be designed into the GORE Fibers to provide unique solutions.
Compared to other synthetic fibers with single density points, density can be modified in GORE Fibers for each application. GORE Fibers can be engineered into high and low density forms, resulting in more open pores that allow space for coating and fillers.
GORE ePTFE fiber makes an outstanding medium for additives or filler materials such as catalysts, carbon, metals and pigments.
A wide range of surface textures is available.
Versatile, High-Performance Solutions
GORE® ePTFE Fibers and Filaments are engineered for flexibility and durability, making them ideal for a wide range of industrial applications. They can be sewn, knitted, or woven into various structures and combined with other materials to achieve specific fabric properties. They can be added to sports strings to improve performance and durability and ropes to increase service life and decrease surface temperature.
