Polytetrafluoroethylene (PTFE) Micropowder

Polytetrafluoroethylene (PTFE) micropowder is a fine powder form of the well-known fluoropolymer PTFE, renowned for its exceptional chemical resistance, high thermal stability and excellent non-stick properties. This micropowder is produced by a special process, resulting in particles that usually range between a few micrometers to tens of micrometers in size. It retains the inherent advantages of PTFE while also offering a range of unique attributes, such as enhanced dispersibility and uniform blending capabilities. These qualities significantly improve the performance of various host materials. As a result, PTFE micropowder finds extensive application as an additive in diverse industries, including plastics, rubber, paints, and inks.
