Cables manufactured with MFA 1041 have met the Telecommunications Industry Association (TIA) Category 6 standard. The extremely low attenuation of MFA 1041 makes it a logical choice for the developing Augmented Category 6 standard. Cables made from MFA 1041 have met the fire performance requirements called out in NFPA 90a ("Standard for Air- Conditioning and Ventilating Systems").

Hyflon® MFA 1041 is not recommended for heavy wall applications where significant thermal stress crack resistance is required.

Key Attributes: Flame Retardant; Good Electrical Properties

Applications: Telecommunications; Tubing; Wire & Cable Applications

Agency Ratings: NFPA Code 90a

COLOR MASTER BATCHES
- Manufacturer recommends that only Color Master Batches based in MFA 1041 be used. Master Batches based on other fluoropolymers can negatively influence the superior processing and electrical performance of MFA 1041. A list of suppliers can be obtained from your Solvay sales representative.

HEALTH SAFETY AND ENVIRONMENT
- Hyflon MFA 1041 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. Please refer to the Material Safety Data Sheets for more information on handling and safety. MFA also complies with Directive 2002/95/EC ("Restrictions of hazardous substances in waste from electrical and electronic equipment" - RoHS), Directive 2000/53/EC ("End of life of vehicles" - ELV) and Directive 76/769/EEC ("Restrictions on the marketing and use of certain dangerous substances and preparations"), as subsequently amended.

PACKAGING AND STORAGE
- Hyflon MFA 1041 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, 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.
- MFA 1041 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.
- MFA can be processed with many different screw designs. Single-flight screws are recommended while barrierflights 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 Saxton mixing or other block mixing sections can improve the processing performance.

EQUIPMENT/TOOLING REQUIREMENTS
- Line Speed: 1,500-2,500 ft./min (450-750 m/min)
- Draw Down Ratio: 80-120
- Draw balance: 0.98-1.05
- Extruder: L/D 24/1-30/1
- Screen pack: Breaker plate only is required
