GORE RASTEX Fibers Weaving Yarn is made from a unique form of expanded PTFE. It has exceptional strength and maintains its dimensional stability better than other synthetic and PTFE fibers. Key Features 30 years of proven performance Low shrinkage at elevated temperatures High tenacity at room and elevated temperatures Low elongation at elevated temperatures Non-contaminating Made from 100% expanded PTFE Non-aging Generally chemically inert Key Benefits GORE RASTEX Fibers Weaving Yarn offers up to 20% material savings due to higher yield/kg compared to competitive yarn Higher tenacity provides more construction options that use less yarn Reduced breakage leads to fewer weaving interruptions Lower elongation means less damage from heavy dust load in filter bags Does not degrade in chemicals, high temperatures or moist environments Longer life for filter bags and cartridges Needle-felting processes can abrade and weaken supporting scrim fibers, and yet it is the supporting scrim that contributes most to the felt's strength. The unique structure of GORE RASTEX Fibers Weaving Yarn makes it stronger and able to retain more strength after felting than other PTFE fibers. The result is stronger felts. Manufacturers can even use a looser scrim weave or smaller fiber to attain the same strength compared to other PTFE fibers, especially when GORE RASTEX Fibers Weaving Yarn is used.
