PTFE Resin / PTFE Suspension Powder / 90-120um size / Moulding
Pelletized free-flow PTFE resin is a kind of white granular
product. It has excellent fluidity, electrical properties,
extremely chemical inertness and outstanding mechanical properties
like low frictional coefficient.. The product can be used for
processing complicated articles. It also can be used for processing
big sheets by compression molding, equal compression molding,
automatic compression molding and exact extrusion. Pelletized
free-flow PTFE resin is propitious for automatic processing that
can shorten processing period and decrease compression molding
Main Application of Everflon PTFE M40
Main Processing Way of Everflon PTFE M40
Everflon® PTFE M usually is processed in two steps: preforming and
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.
