Processing Recommendations

 

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.

 

 

Supply Form

 

PTFE Micropowder J14 is supplied in 50 lb. drums with a polyethylene liner.

 

Storage

 

PTFE Micropowder J14 has a 3 year shelf life. It should be kept in a clean and dry place in its original unopened container at temperatures below 30°C (86°F).
