DAIKIN-NEOFLON ®PFA

 

 

Daikin PFA is a copolymer of tetrafluoroethylene (TFE) and perfluoroalkyl vinyl ether. DAIKIN-Neoflon® PFA has the molecular structure shown below. Melting points range from 295 to 310 ̊C.Compared to FEP, the copolymerization composition ratio of the comonomer content

is small, and PFA has a chemical structure that is close to PTFE. Therefore, PFA has a higher melting point and higher heat resistance than FEP. Daikin PFA has excellent mechanical strength at high temperatures, and has excellent moldability for easy processing using extrusion, compression, blow, transfer, and injection molding methods.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Thermal Properties: Due to the high bonding strength of the carbon, fluorine, and oxygen atoms, PFA demonstrates̊̊ nearlẙ the same̊ outstanding capabilities as PTFE in temperat ures ranging from -200 C to 260 C. From 200 C to 260 C, PFA maintains its flexibilitẙ̊ without a loss of toughness. The maximum continuous use temperature use for PFA is 260 C (500 F). This is the highest temperature for continuous use of any fluoropolymer resin.

 

Chemical Properties: Daikin PFA provides excellent chemical resistance.

 

Electrical Properties: A low dielectric constant and dissipation factor exist along with high dielectric strength over a wide range of frequencies and temperatures.

 

 

Low Friction: Daikin PFA is inherently non-cohesive and it is extremely repellant of water, oil and other substances. Furthermore, its surface is characterist ically slippery.

DAIKIN-NEOFLON ® PFA

 

Pellets Daikin PFA pellets have good melt flow characteristics and can be processed in the same manner

as other thermoplastic resins. The semiconductor grades (SH Series) have reduced elusion ions, and are

used for various components for semiconductor manufacture lines where cleanliness is essential.

Polymer Processing of Daikin

 

PFA Pellets

 

Molding

 

PFA can generate traces of highly corrosive gas when it decomposes at the molding temperature, requiring materials of construction with outstanding corrosion and heat resistance for extrusion and injection-molding equipment used for molding.

 

 

Extrusion molding

 

In extrusion, covered electrical wire, pipe, tubing, monofilament, film, etc. can be formed by extrusion. Extruders with a cylinder diameter from 30 to 65 mm are most commonly used. A rapid compression type screw with an L/D ratio of 20 to 24 and compression ratio of 2.5 to 3.0 is also used.

 

 

Injection molding

 

DAIKIN PFA has good injection moldability and can easily mold complicated profiles, such as semiconductor manufacturing jigs, electrical and electronic components. A screw-type molding machine is generally used, and the spool, runner, and gate must be made slightly thicker than normal, as

 

short as possible, and have the cross section nearly circular to reduce molding strain. Hard chromium-plated dies are generally used.

 

 

Transfer molding

 

Pipe, valves, joints, and other linings for the chemical industry, brewing industry, etc. can be formed by transfer molding PFA. Components subject to lining processi ng, such as pipes and valves,

 

are used for the outer die or inner die, and are heated to temperatures that exceed the melting point. PFA resin that has been separately melted inside the cylinder is pressu re-fed into the components̊ and cooled while under pressure. Components̊ can be molded at die temperatures of 350 to 370 C and resin temperatures of 350 to 390 C.

 

 

Dispersions Neoflon PFA dispersions are water-based coatings with bases of co-polymers of tetrafluoroethylene

and perfluoroalkylvinylether.
