Hyflon® PFA & MFA® 

Hyflon® PFA resins are perfluoropolymers with the highest temperature rating and broadest chemical resistance of all melt processable fluoropolymers.

Several Hyflon® PFA families are available:

• Hyflon® PFA P and M for the most high performance applications.
• Hyflon® PFA H for high-purity applications.

All Hyflon® PFA products are classified in accordance with ASTM D3307.

Hyflon® MFA®, low melting point PFA resins, are a cost effective alternative to FEP and ideal for wire and cable, and chemical process industry end uses.

Hyflon® MFA® family also include:

• Hyflon® MFA® F for foamed coaxial cable jacketing and insulation.

Hyflon® MFA® F series meets NFPA 90a fire performance standards.

Extrusion

Hyflon® PFA polymers are suitable for extrusion using techniques normally applied for other thermoprocessable plastics.

Injection Molding

Hyflon® PFA 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® PFA 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.

Transfer Molding

Hyflon® PFA can be used to produce lined items by transfer molding. This technique basically consists of the following steps:

• Melting and plasticizing
• Injection in a hot mold
• Packing and cooling

Extrusion

Hyflon® MFA® polymers are suitable for extrusion using techniques normally applied for other thermoprocessable plastics. Processing of Hyflon® MFA® F1930X requires a nucleating master batch for foamed coaxial cable cores of 0.05 in. to 0.50 in.

Injection Molding

Hyflon® MFA® 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® MFA® 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.

The Hyflon® PFA P series offer:

• Higher Melting Point >300°C

The Hyflon® PFA M series offer:

• Intrinsic processing stability
• Improved surface smoothness
• Remarkably higher transmittance values

The Hyflon® PFA H series offer:

• Improved surface soothness
• Exceptional clarity and transmittance

A novel combination of properties

Hyflon® MFA® is a family of perfluoropolymers with a lower melting point (265-275°C), exceptional stress crack resistance, high flex life and continuous service temperatures up to 225°C.

Hyflon® MFA® offers:

• Chemical and permeation resistance equivalent to traditional PFA
• Exceptional optical clarity
• UV light transparency

Wire & Cable

Hyflon® PFA is used in advanced electronics such as keypads and LED displays in tighter spaces requiring the use of wire & cable materials ever more reliable and safe due its key properties.

Hyflon® PFA offer excellent mechanical properties at high temperatures for wire & cable insulation, heat tracing wiring, oilwell logging wires, sensor wires and avionics along with high reliability and long-term ageing resistance.

Photovoltaic Frontsheets

Hyflon® PFA innovative and customized films and resins are used in the realization of flexible frontsheets thanks to their outstanding properties as:

• Long-term weatherability
• Optimal light transmission
• High moisture barrier for front- and backsheet hydrolysis protection
• Fire resistance
• Electrical insulation
• Light weight

Wire & Cable

Hyflon® MFA® resins are used to replace FEP in such applications as automotive wiring, heater cables, coaxial cables and down hole cables.

Hyflon® MFA® F has excellent thermal stress crack resistance and good mechanical properties allow it to be used continuously up to 225°C. Hyflon® MFA® 1041 is widely used for high speed extrusion of insulation for plenum rated LAN cables, thin walled coaxial cables and consumer electronics.

Hyflon® MFA® F1850-0010 and F10640 are completely pre-compounded foamable fluoropolymers ideal for manufacturing coaxial cables and primary insulation for unshielded twisted pairs. Hyflon® MFA® F1930X is a medium-low melt flow rate resin delivering fire characteristics for heavy wall construction.

Specific Applications in the Chemical Process Industry

Hyflon® MFA® F can be widely used in the chemical process industry due to its virtually universal chemical resistance up to 220-230°C.

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 PFA improving cleanliness, reducing pressure drop and reducing wall build-up in slurries or mixtures.
