Daikin PTFE (polytetrafluoroethylene) molding powders are excellent, fine cut resins, well suitedfor a variety of demanding chemical, mechanical, electrical and non-stick surface applications.These PTFE resins are fully fluorinated and have the best thermal, electrical, and chemical properties of all fluoropolymers with a continuous service rating of 500°F (260°C). Daikin PTFEmolding powders are available in homopolymer and modified fine cut grades.Daikin PTFE Molding PowdersDaikin America, Inc. 20 Olympic Drive, Orangeburg, New York (845) 365-9500 (800) 365-9570 Fax: (845) 365-9515 Web: www.daikin-america.comP r o d u c ti n f o r m a t i o nThermal Properties: 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 temperaturestrength.Chemical Properties: 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. Electrical Properties: 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 materialsfrom adhering to them. Typical Applications: Chemical/Mechanical—Packings, gaskets, diaphragms, bellows, corrosion-resistant linings, pipingcomponents, 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.Daikin PTFE Molding PowdersTest Method/Condition M-12 M15 M-15X M-18 M-111 M-112THERMALMelt Point, °C DSC 2nd melt 327 327 327 327 324 323Continuous Service 500°F (260°C) 500°F (260°C) 500°F (260°C) 500°F (260°C) 500°F (260°C) 500°F (260°C)MECHANICALTensile Strength1 MPa (psi) ASTM D 4894 43(6,237) 43(6,237) 43(6,237) 43(6,237) 40(5,802) 40(5,802)Elongation1, % ASTM D 4894 400 400 400 400 500 425Compressive Strength2 ASTM D 6950.2% off set, MPa (psi) 7.6(1,102) 7.8(1,131) 7.8(1,131) 7.8(1,131) 8.7(1,262) 7.7(1,117)1% strain 5.0(725) 5.0(725) 5.0(725) 5.0(725) 5.9(855) 4.7(682)25% strain 28.2(4,089) 28.1(4,075) 28.1(4,075) 28.1(4,075) 28.6(4,147) 28.3(4,103)Compression Creep ASTM D 621Characteristics...Total Deformation, % 25°C-13.7 MPa 18.7 17.2 17.2 17.2 10.6 12.9Compression Set, % 8.8 8.6 8.6 8.6 3.0 4.8...Total Deformation, % 100°C-13.7 MPa 31.4 33.3 33.3 33.3 21.7 24.9Compression Set, % 18.5 20.1 20.1 20.1 7.4 8.7...Total Deformation, % 200°C-6.9 MPa 26.7 27.0 27.0 27.0 14.9 17.7Compression Set, % 15.3 16.0 16.0 16.0 4.1 5.0MIT Flexural Life ASTM D 2178 7 x 106 5 x 106 5 x 106 5 x 106 3 x 106 27 x 106SVI (Stretching Void Index) ASTM D 4895 270 300 300 300 62 40ELECTRICALDielectric Breakdown 12.5 10.0 10.0 10.0 13.5 13.0Voltage, kV/0.1mmVolume Resistivity, ? cm ASTM D 257 > 1018 > 1018 > 1018 > 1018 > 1018 > 1018Surface Resistivity, ?

Therefore, special-processing techniques are required to mold it. The basic molding method is to preform the powder, sinter it, and cool it. Physical and electrical properties of the molded product depend upon the preform pressure, sintering temperature, sintering time, and cooling rate.

M-12, M-15, M-111 and M-112 are packaged in 110 lb. fiber drum containers with poly liners.Quality/Regulatory: Daikin-Polyflon PTFE molding powders comply with the requirements set forth in FDA specification21 CFR 177.1550.Daikin America’s manufacturing facility is registered to ISO-9001-2000 (Quality System) and ISO-14001 (Environmental System).Storage &Handling: Molding powders tend to form agglomerates easily; therefore, do not store large quantities of powder in deep containers, and avoid strong vibrations and shock. Storage at temperatures above19°C tends to promote agglomerate formation. Should agglomerates form, keep the powder at lessthan 19°C (ideally 15°C or below) for two days then sift through a coarse screen and allow to come to room temperature before molding.Safety: When PTFE resins are heated to temperatures above 260°C, some decomposition products may begiven off. These decomposition products may be harmful, and inhalation of these fumes must beavoided. Ovens, process equipment and working area must be adequately ventilated.
