TEFLON (PTFE) BALLS


Low weight fluorinated semicrystalline polymer balls, they provide exceptional corrosion resistance and are used into high temperature applications.

Mechanical and wear resistance properties are lower than other plastic materials. Good electric insulators, they are auto lubricant. Teflon properties change if they are exposed to electromagnetic radiations.

 

Applications

Ball bearings, special valves (very aggressive environments), measurement and medical instruments, appliances. They are used into foodstuff, paper, chemical, electronic, pharmaceutical industry.

Corrosion Resistance

Teflon balls provide exceptional corrosion resistance properties, they are resisting even in contact with industrial acids or caustic substances. They suffer

corrosive phenomena only against molten alkaline metals and fluorides at elevated temperatures.
