PTFE Resin / PTFE Suspension Powder / 90-120um size / Moulding Processing
PTFE is composed of polytetrafuluoroethylene, the most commonly used fluoroploymer. PTFE has a very long chain molecular structure in which all of the hydrogen atoms of polyethylene are replaced by fluorine atoms.
PTFE is superior in heat resistance and chemical resistance compared with the other plastics. These properties result from stable chemical structure consisting of only carbon and fluorine atoms with the highest electro negativity.
Main Application of Everflon PTFE M40
Main Processing Way of Everflon PTFE M40
Everflon® PTFE M usually is processed in two steps: preforming and sintering:
The powder is first compacted into a preformed shape approximating that of the desired molding. A precise
heating (sintering) and cooling cycle is then used to consolidate the molding at temperatures above the crystalline melting point of the neat powder.
The properties of a finished molding are dependent on perform pressure, sintering time and temperature, and cooling rate.

Everflon® PTFE Suspension Powders’ preforming is easiest when the resin is uniformly between 21–27 °C (70–80 °F). As temperatures decline below this range, the resin will be increasingly difficult to mold without cracks and problems with condensed moisture. Higher temperatures inhibit flow and promote lumping.
Storage conditions should be set accordingly. Cleanliness is a critical requirement for successful use of Everflon® PTFE Suspension Powder. The white resin and high sintering temperatures cause even small foreign particles to become visible in finished moldings. Keep resin drums closed and clean. Good housekeeping and careful handling are essential.
Properties of Everflon PTFE Resins
Everflon® PTFE Suspension Powder is preferred for moldings requiring optimum mechanical and electrical properties. Its low bulk density limits the size of moldings from a given mold or press opening. It is often preferred for making filled compounds, especially with metal powders that are difficult to mix because of density differences.
