F4B-N and F4B-T Teflon Woven Glass Fabric Copper-Clad Laminates
Introduction to F4B-N and F4B-T
F4B-N and F4B-T Teflon woven glass fabric copper-clad laminates are essential materials for manufacturing Teflon woven glass fabric copper-clad laminates. The production process involves dipping treatment of the Teflon resin on alkali-free woven glass fabric, followed by drying, baking, and sintering to formulate the microwave material. These products are characterized by heat resistance, insulation, low loss, excellent electrical performance, and non-adhesion properties. They are widely used in various industries including electronics, motors, aviaţie, textiles, chemicals, and food. In microwave devices, they serve as bonding films for multilayer printed circuit boards.
