Introduction
NEOFLON PFA is a copolymer of tetrafluoroethylene and perfluoroalkyl vinyl ether, NEOFLON PFA is a compound of carbon atoms and fluorine atoms in which a perfluoroalkoxy radical is bonded to the carbon chain in the following molecular structure.

PFA分子式

NEOFLON PFA has better mechanical strength at high temperatures than NEOFLON FEP, and has excellent moldability for easy of processing by extrusion, compression, blow, transfer, and injection molding methods. Due to the high bonding strength of the carbon, fluorine and oxygen atoms, NEOFLON PFA demonstrates nearly the same outstanding capabilities as PTFE in temperatures ranging -200℃~+260℃.NEOFLON PFA has excellent transparency for use in melt-flow processing.

1.NEOFLON PFA Features
1-1 Moldability
While maintaining the outstanding characteristics of PTFE, NEOFLON PFA is a fluoropolymer resin with good melt flowability, which can be processed similar to other thermoplastic resins.

1-2 Corrosion-resistance
NEOFLON PFA is not effected by most chemicals.

1-3 Retention of mechanical strength through a wide temperature range
From-200℃ up to +260℃,PFA maintains its flexibility without a loss of toughness. The maximum continuous use temperature for PFA is 260℃ (500℉). This is the highest temperature for continuous use of any fluoropolymer resins.

1-4 Electrical characteristics
• Low, stable dielectric constant throughout a wide frequency range
• Extremely low, stable dissipation factor throughout a wide temperature and frequency range
• High volume resistivity
• Extremely high dielectric breakdown strength

1-5 Flame resistant
NEOFLON PFA has excellent flame resistance.

1-6 Weatherability
Even after long exposure to the elements, PFA’s properties will not change.

1-7 Non-sticking and low friction
PFA is inherently noncohesive and it is extremely repellant of water, oil and other substances. Furthermore, its surface is characteristically slippery.

4.Processing of NEOFLON PFA
NEOFLON PFA  has a good melt flow processability and excellent thermal stability.
NEOFLON PFA  can, be molded by the same injection, extrusion, blowing, and compression molding processes used for other thermoplastic resins.
NEOFLON PFA  AP-201 in particular has a low viscosity and is suitable for use in molding complex shapes. NEOFLON PFA AP-230 is particularly suited for use in corrosion resistant linings requiring stress crack resistance.
The mold temperature range for both AP-210 and AP-230 is 350℃~380℃(662~770℉). Molding conditions must be selected according to the specific molding method used and the shape the final product.
The molding speed in injection molding must be less than the critical shear rate or melt fracture will occur, resulting in a rough surface on the molded part.
Fig.12 shows the relationship between temperature and melt viscosity.
Fig.13 shows the relationship between shear stress and shear speed.
Fig.12 Melt Viscosity vs TemperatureFig.13 Shear Rate vs Shear Stress
When molding NEOFLON PFA, using injection, extrusion, or blow molding machines, a highly corrosive resistant material should be used to coat all surfaces which will directly in contact with the molding resin. NEOFLON PFA will begin to decompose at 380℃(788℉). Extended use of such high temperatures should be avoided.
 
4-1 Injection molding
Molding of semi-conductor manufacturing equipment, instruments for physics, chemistry and other sciences, and electronics and electrical parts is possible by this method.
Normal screw-type injection molding machines are used.
In order to reduce molding deformation, the sprue, runner, and gate should be slightly large and as short as possible, and the mold cavity should be nearly round in cross-section. A hard chromium-plated mold should be used, and it must be heated to between 150~200℃(302~392℉).
The following table shows a typical set of injection molding conditions.

4-2 Extrusion molding
Coated electrical wiring, pipe, tubing film monofilament, and similar products can be produced by extrusion molding.
Extruder cylinders usually have a diameter from 30~65mm, with a screw L/D ratio of 2.0~24 Rapid compression screw type units with a compression ratio of 2.5~3.0 are used. Table 10 shows typical extrusion molding conditions.

4-3 Compression molding
Processing of molded sheet products with thickness of 1-2mm is possible by using presses equipped with both electrically heating panels capable of heating to 360(680℉) and with water cooling panels. Processing is also possible with presses in which these panels are separated. The molds are usually carbon steel with a hard chromium plating. If the molded product adheres to the mold surface and is not easily release, line the mold with aluminum foil.

7.Caution on Handling
The following points should be followed to ensure safety when handling NEOFLON PFA
• WARNING: VAPORS HARMFUL IF INHALED. The work area should be abequately ventilated at all times, because HF, COF2 begin to be produced at approximately higher then 260℃ and the volume increases at approximately 380℃. If PFA is incinerated, the acidic gases must be removed by alkaline scrubbing techniques.
• Personnel should be cautioned against inhaling the fumes liberated during processing and provided with suitable protective equipment.
• Smoking should be prohibited in work areas, since smoking fluoropolymer contaminated tobacco may result in inhalation of decomposed gas. Do not bring tobacco in the work area.
• Avoid breathing dust and contact with eyes.
• Wash hands and face after handling.
• Waste generated during processing should be treated by waste treatment specialists and/or licensed waste contractor disposed of in a accordance with federal, state and local waste disposal regulations.
• Read the “Material Safety Data Sheet” before use.
