Glass Filled PTFE Precision Balls

Glass Filled "GF" plastic balls are filled with fiber glass and provide mechanical, dimensional, and heat resisting properties. Depending on the needs of the application, Glass Filled PTFE is reinforced with glass fibres with the percentage range varying between 5% and 40%. Because of these properties, Glass Filled PTFE balls are commonly used in valve seat applications. Other applications of glass filled PTFE balls are gaskets, shaft bearings, and filter technology.
