Ultraflon MP-25

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 Typical Properties: Property Unit of Measure Test Method MP-8T  Appearance  N/A  Visual Observation  Pristine White  Powder Bulk Density  g/L  ASTM D5675  310  Secondary Particle Size  µ  Laser Particle Size Analysis  4  Primary Particle Size  nm  Laser Particle Size Analysis  300  Specific Surface Area  m²/g  Nitrogen Absorption  8.2  Melt Point Temperature  °C  ASTM D5675  332
