Properties

A Family of Products that Delivers the Performance You Need

Hyflon® perfluoropolymers offer a unique set of properties to meet extreme performance requirements, including very cold temperature resistance, inherent flame resistance, chemical inertness, low surface energy, exceptional dielectric properties, and excellent mechanical characteristics.

Due to its virtually universal chemical resistance up to 220-230°C (428-446°F), Hyflon® MFA F can be widely used in the chemical processing industry. Specific applications include protective linings of tanks, reactors and heat exchangers, tower packing, and applications where FEP is also used.

The surface of Hyflon® MFA is up to 10 times smoother than standard perfluoropolymer, improving cleanliness, reducing pressure drop, and reducing wall build-up in slurries or mixtures.

Hyflon® MFA F has excellent thermal stress crack resistance and good mechanical properties that allow it to be used continuously up to 225°C (437°F). In particular, Hyflon® MFA 1041 is widely used for high-speed extrusion of insulation for thin-walled cables for a variety of applications.

Relative Performance of Melt Processable Fluoropolymers

Hyflon® perfluoropolymer resins offer excellent mechanical properties at high temperatures for wire & cable insulation, heat tracing wiring, oil well logging wires, sensor wires, and avionics along with high reliability and long-term aging resistance.

Processing

Hyflon® perfluoropolymers are truly thermo-processable resins. When heated above their melting point they do not cross-link and undergo a consistent reduction of viscosity which makes it possible to process them with the standard techniques used for common plastics. The outstanding thermal stability of Hyflon® perfluoropolymer allows long residence times in the molten state without degradation or reduction of properties.

Extrusion

Hyflon® perfluoropolymers are suitable for extrusion using techniques normally applied for other thermo-processable plastics, provided that the extruder is equipped with corrosion-resistant alloys. 

Injection Molding

Hyflon® perfluoropolymers can be injection molded following the same processes used for normal thermoplastic resins. The low viscosity grades are particularly designed for injection molding of complex shapes.

Compression Molding

Hyflon® perfluoropolymers can be molded by compression to obtain semi-finished items such as sheets, rods, and film. The most suitable molding conditions must be selected according to the specific process and the shape of the final item. In all cases, the molding temperature will be in the range of 340 - 380 °C (645 - 715 °F).

Transfer Molding

Hyflon® perfluoropolymers can be used to produce lined items by transfer molding. Typical transfer molding resins are the low-MFI grades, such as Hyflon® P420 and Hyflon® M620.
