Glass-Filled PTFE Film - T 0.5mm 300mm x 300mm

Glass-Filled PTFE Film combines the chemical inertness and low-friction properties of PTFE with the mechanical reinforcement of finely dispersed glass fibers, resulting in improved wear resistance, dimensional stability, and reduced creep. The film format offers a smooth, durable surface suitable for use in high-load bearing liners, electrical insulation, and chemically resistant sealing layers. Industries apply it in aerospace structural insulation, low-wear slide surfaces in industrial machinery, and gaskets for chemically aggressive environments. Specific applications include thrust washers in high-performance pumps, thermal barrier layers in electronics, and non-stick conveyor liners for abrasive materials. In research, the film is used to study composite tribology, optimize filler dispersion for mechanical reinforcement, and develop high-performance laminate structures. The synergy of PTFE’s surface chemistry with glass’s reinforcing properties ensures reliability in demanding engineering applications.
