PTFE Balls
PTFE Balls are an engineered plastic product from Goodfellow, available in 5 variations. These polytetrafluoroethylene (PTFE) balls exhibit excellent chemical resistance, high temperature resistance, low friction, and electrical insulating properties. PTFE balls find use across scientific and industrial applications including bearings, valves, and seals where lubricity, chemical inertness, and heat resistance are required.
