Low MW PTFE micropowder

APPLICATIONS FOR LOW MW PTFE (MICROPOWDER OR FLUOROADDITIVE) 609 used to create parts for use in the semiconductor industry include [24,25]... 

Polymer chemistry and architecture are key to the properties for which PTFE micropowders are used and the production process dictates much of the architecture. The PTFE micropowders are produced by three general processes (1) direct polymerization of low MW PTFE [28-32], (2) irradiation and grinding of high MW PTFE [33-35], and (3) thermal degradation of high MW PTFE [36,37]. 

As noted above, surface area is an important property for many micropowder applications. The only directly polymerized low MW PTFE available commercially is based on dispersion polymerization (high surface area) so either irradiated granular or thermally degraded PTFE is employed when a low surface area is preferred for the application.
