Ultraflon MP-25 is a coagulated dispersion-based PTFE powder and has a comparatively high molecular weight. It possesses an agglomerated particle size of 4 microns, but breaks down to its primary particle size of 300 nanometers upon shearing. This allows MP-25 to exhibit an extremely high surface area after processing, impacting viscosities. The particles are engineered to be spherical, which makes MP-25 particularly well suited as an additive for various applications and processes. This product exhibits superior thermal and chemical stability.

Typical Applications Include (but not limited to):

• catalyst or electrocatalyst additive to optimize the water management in fuel cells
• prevent the electrolyte flooding in alkaline fuel cells and anion exchange membrane fuel cells
• adjusting the hydrophobic/hydrophilic nature of electrocatalyst layers for fuel cells and electrolyzers
• adjusting the hydrophobic/hydrophilic nature of gas diffusion layers for fuel cells and electrolyzers
• binder agent for gas diffusion layers and microporous layers
• modification of the surface properties of bipolar plates and current collectors for fuel cells and electrolyzers
• dry lubricants, aerosols, specialty greases
• engineered polymer additive, polymeric compound additive, friction/wear reducing additive
• corrosion-resistant coatings, cookware coatings, mold release, lubricants and specialty oils
