| Hyflon® F is a new family of PFA polymers which combine excellent mechanical characteristics to properties such as chemical inertness, high flexural endurance, inherent flame resistance, low surface energy and exceptional dielectric properties. Hyflon® PFA F1520 is a low melt flow rate multi purpose resin with an exceptional stress crack resistance, continuous service temperature up to 225°C and a 100-150x10³ cycles flex-life (on a 0.3mm film, ASTM D2176). Key Attributes: Flame Retardant; Good Flexibility; High ESCR (Stress Crack Resist.); Low Flow Applications: General Purpose; Wire & Cable Applications COLOR MASTER BATCHES
- Manufacturer recommends that only Color Master Batches based in Hyflon PFA be used. Master Batches based on other fluoropolymers can negatively influence the superior processing and electrical performance of the resin. HEALTH SAFETY AND ENVIRONMENT
- Hyflon PFA F1520 is a very inert polymer and it is not harmful if used and handled according to standard processing procedures. If handled inappropriately, it may release harmful toxic chemicals.
- Hyflon PFA F1520 does not contain any RoHS or WEEE substances. Hyflon MFA F1520 is not produced using APFO and contains no APFO. Please refer to the Material Safety Data Sheets for more information on handling and safety. PACKAGING AND STORAGE
- Hyflon PFA F1520 resin is available in 25 kg (55 lbs.) and 500 kg (1102 lbs.) packaging. Though it has an indefinite shelf life, it is recommended to store it in a clean area, protected by direct sun light and possible contamination. Extrusion Notes: EXTRUSION PROCESSING GUIDELINES
- As with other fluoropolymers, Hyflon MFA is corrosive in the melt. Therefore all parts coming into prolonged contact with the melt should be made with corrosion resistant materials such as Hastelloy®, Inconel®, Monel® or Xaloy®. Chrome or nickel plating is not recommended since they are typically only sufficient for brief processing tests.
- F1520 is suitable for extrusion using techniques normally applied for other thermo-processable plastics, provided that the extruder is equipped with corrosion resistant alloys. Extruders with L/D ratio of 20:1 to 30:1 are recommended. Extruders should be equipped with independently controlled heaters capable of accurate temperature control up to 450°C (840°F). An overview of the temperature, tooling and equipment requirements are in the following tables.
- Many different screw designs can be used. Single-flight screws are recommended while barrier-flights should be avoided. A typical screw design consist of a long feed section (at least 12 flights), followed by a 2 to 6 flight transition and a 5 to 7 flight metering section.
