Hyflon® MFA® F1540 is a medium-high melt flow rate multi purpose resin with an exceptional stress crack resistance, continuous service temperature up to 225°C and a 13-15 x 10³ cycles flex-life (on a 0.3 mm film, ASTM D2176).

Key Attributes: Flame Retardant; High ESCR (Stress Crack Resist.); High Flow

Applications: General Purpose; Wire & Cable Applications

COLOR MASTER BATCHES
- Manufacturer recommends that only Color Master Batches based in MFA® 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® MFA® F1540 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® MFA® F1540 does not contain any RoHS or WEEE substances. Please refer to the Material Safety Data Sheets for more information on handling and safety.

PACKAGING AND STORAGE
- The Hyflon® MFA® F1540 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: WIRE AND CABLE PROCESSING GUIDELINES
- As with other fluoropolymers, 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.
- Hyflon MFA F1540 is applied onto wire using tubing extrusion techniques similar to other thermoplastic materials. 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, followed by a 2 to 6 flight transition and a 5 to 7 flight metering section. The addition of a block mixing section can improve the processing performance.

EQUIPMENT/TOOLING REQUIREMENTS
- Line Speed: 200 to 350 m/min (700 to 1200 ft./min)
- Draw Down Ratio: 80 to 120
- Draw Balance: 0.96 to 1.04
- Extruder L/D: 20/1 to 30/1
- Screen Pack: Breaker plate only is required.
