Teflon Balls (PTFE)
PTFE – Teflon balls have a nonstick, slippery surface. Fluorinated semicrystalline polymer balls are light in weight and used in high temperature applications because they have excellent corrosion resistance. Compared to other plastic materials, it has weaker mechanical and wear resistance qualities. They are auto lubricant and effective electric insulators. If Teflon is subjected to electromagnetic radiation, its characteristics alter.

Corrosion Protection:
Teflon balls have outstanding corrosion resistance qualities; they can withstand contact with caustic or industrial chemicals. Only when exposed to molten alkaline metals and fluorides at high temperatures can they experience corrosive events.
Applications:
Include appliances, measuring and medical equipment, special valves for use in extremely abrasive environments, and ball bearings. They are utilized in the chemical, electrical, pharmaceutical, paper, and food industries.
