Why choose PTFE coating for a Spiral/Helical Impeller?
Chemical Inertness: PTFE is resistant to almost all chemicals. This prevents the metal impeller from corroding or reacting with the batch media, making it essential for pharmaceutical or aggressive chemical synthesis .
Non-Stick (Release): The low friction surface prevents media from caking or adhering to the spiral blades, which is critical when mixing adhesives, resins, or biological materials .
Wear & Hydrophobicity: Studies show that a PTFE top layer increases surface hydrophobicity (water repellence), which helps reduce slurry and cavitation erosion wear on the impeller blades .
