Typical Properties
Polymist® and Algoflon® L PTFE micronized powders are free flowing powders used as additives in a wide range of materials such as thermoplastics, coatings and paints, inks, elastomers and lubricants (i.e., greases, oils, dry lubricants) to enhance processing or end-use performance characteristics.
