Daikin POLYFLON™ PTFE M-112 Polytetrafluoroethylene Molding Powder
Categories: Polymer; Thermoplastic; Fluoropolymer; Polytetrafluoroethylene (PTFE); Polytetrafluoroethylene (PTFE), Molded

Material Notes: DAIKIN-POLYFLON PTFE (polytetrafluoroethylene) molding powders are well suited for a variety of demanding chemical, mechanical, electrical and non-stick surface applications. These fully fluorinated have excellent thermal, electrical, and chemical properties, with a continuous service rating of 500°F (260°C). DAIKIN-POLYFLON PTFE molding powders are available in homopolymer and modified fine cut grades.

Daikin PTFE molding powders can be used continuously at temperatures up to 260°C (500°F) and for short periods of time at higher temperatures. They also possess excellent low temperature strength.

Daikin PTFE molding powders are completely inert to attack by all chemicals except high temperature, high-pressure elemental fluorine gas, molten alkaline metals and chlorine trifluoride.

The non-polar molecular structure makes Daikin PTFE molding powders ideal for use as high frequency insulating material. The dielectric constant and dissipation factor are uniformly low over a wide frequency range.

Low Friction: Under ordinary conditions of use, Daikin PTFE molding powders possess the lowest coefficient of friction of any solid material. Also, the non-stick properties of these products prevent most materials from adhering to them.

Typical Applications: Chemical/Mechanical—Packings, gaskets, diaphragms, bellows, corrosion-resistant linings, piping components, pump parts, O-rings, V-rings, bushings, slide bearings, etc. Electrical/Other—Insulating skived tape, insulating sleeves, terminals, connectors, sockets, spacers, electronic parts, laboratory equipment, etc.
