Features

  • Coagulated powder of unsintered low-molecular –weight PTFE
  • Coagulation of fine powder.Can be made smaller with hard dispersion.
  • Soft grain, prone to disfigurement
  • Relatively large specific surface area, making it difficult to deposit when dispersed in a liquid.
  • Large oil adsorption.
  • Tends to come out to the coating surface.
  • Fine powder, dispersed close to the state where very fine particles
  • Fine powder, dispersed close to the state where very fine particles( Dp 50= 0.3 µm) have coagulated.
  • Can be dispersed in liquid with the particles measuring 1 µm or less in size.
  • Such fine – powder features as viscosity and fibrillation are suppressed for easy handling.
