PTFE balls provide excellent chemical resistance, very low friction and non-stick surface performance. They are suitable for valves, pumps and sealing applications where metal balls may corrode or react with the working media.
To Share:
PTFE balls are commonly used as valve, pump and sealing balls in chemical flow-control systems.
PTFE balls are manufactured from polytetrafluoroethylene materials, commonly known in the industry as PTFE or Teflon® materials.
They are lightweight, non-metallic and highly resistant to many corrosive chemicals.
Compared with metal balls, PTFE balls provide better chemical compatibility, lower friction and non-stick performance, making them suitable for check valves, dosing pumps, sealing components and flow-control applications.
Due to their relatively low mechanical strength, PTFE balls are generally not used for high-load bearing or high-wear mechanical applications.
