Abstract
The present disclosure provides poly(tetrafluoroethylene) (PTFE) microparticles with a Dv50 of about 20 μm to about 30 mm and a specific surface area (SSA) of at least about 3.0 m/g when measured by a multipoint BET method of ISO 9277. Such PTFE microparticles can be obtained via a method including thermomechanically degrading scrap PTFE in the presence of air and/or oxygen and reducing the particle size of the resultant degraded PTFE.
