3M™ Dyneon™ PTFE Micropowders can be used as  additives in many applications and at concentrations  typically from 5 to 20%. Homogeneous incorporation  is the single most important process and application  consideration. Due to poor flow properties of the  micropowder it is recommended that the micropowder  and matrix material both be at a temperature below  30°C (86°F). However, in the case of thermoplastic  blends, the micropowder may be incorporated into the  melt. Dyneon PTFE Micropowder J14 can be dispersed  using a variety of mixing equipment. Depending upon the  application, high speed mixers and tumble blenders have  been successful for dry blends, while propeller mixers  work well for wet mixtures such as solvents and oils. Glass  bead mills should be used for relatively high viscosity  mixtures and roll mills for very high viscosity applications,  such as lubricating greases and oils.

Features and Benefits

• Low molecular weight  PTFE powder • Agglomerate particles • Friable (can be broken down  into smaller particles) • High specific surface area • Broad chemical resistance and  temperature range of use Used as an additive to: • Reduce coefficient of friction  or impart low surface energy • Thicken or increase viscosity  of matrix material
