PTFE filled with Glass Rod

PTFE filled with Glass Rods are made from a composite material that has a balance of properties by combining polytetrafluoroethylene (PTFE) polymer with glass filler. We offer 37 variations of these versatile rods that provide chemical inertness and low friction, while the glass enhances mechanical strength and rigidity. The percentage of glass filler can be varied to tune mechanical and thermal properties for applications like bearings, seals, valve seats and electrical insulators. This makes PTFE filled with Glass Rods valued across industrial, chemical and medical settings.
