March 2026 – Shanghai Shenhui Technology Development Co., Ltd. has recently launched a new series of PFA (Perfluoroalkoxy Resin) products targeting overseas markets including India and Italy. PFA is a high-performance fluoroplastic that can be melt-processed like ordinary plastics while retaining the excellent corrosion resistance and high-temperature performance of PTFE (the "Plastic King"). It has become an indispensable core material in fields such as semiconductors, chemical anti-corrosion, and wire and cable.
Simply put, PFA is an "upgraded version" of PTFE.
PTFE (commonly known as "Teflon") has excellent corrosion resistance but cannot be melt-processed—it can only be shaped like ceramics through compression molding, making it difficult to form. PFA, however, retains all the advantages of PTFE while can be injection molded and extruded like ordinary plastics, greatly expanding its application range.
To use an analogy: if PTFE is like "stone" (can only be carved), then PFA is like "metal" (can be cast and forged)—more flexible to process and broader in application.
| Advantage | Plain Explanation | Technical Parameters |
|---|---|---|
| High Temperature Resistance | Stable performance from -196°C cryogenic to 260°C high temperature | Continuous use temperature -196°C to 260°C |
| Corrosion Resistance | Resists almost all strong acids and alkalis except molten sodium metal and fluorine gas | Resists all chemicals except molten alkali metals and fluorine |
| High Purity | Extremely low metal ion extraction, won't contaminate semiconductor chips or pharmaceuticals | Metal ion content ppb level (parts per billion) |
| Good Strength | Stronger than PTFE, resists deformation during long-term use | Tensile strength 24-35MPa, elongation 300-350% |
| Easy Processing | Adjustable melt index, suitable for injection molding, extrusion, and other processes | Melt index 1-30 g/10min (customizable) |
| Excellent Insulation | Outstanding electrical properties, suitable for high-frequency cable insulation | Volume resistivity >10¹⁸Ω·cm |
Pipes and fittings for transporting high-purity chemicals and ultrapure water
Tanks for wafer cleaning, components for etching equipment
Wafer storage boxes, valve seals
Why must it be PFA? In semiconductor manufacturing, chemical purity requirements are extremely high. Even ppb-level (parts per billion) metal impurities can cause chip rejection. PFA is currently the only melt-processable plastic that meets ultra-high purity requirements.
Linings for storage tanks holding strong acids and alkalis
Pipes, pumps, and valves for conveying corrosive media
Reactor linings, sealing gaskets
Why choose PFA? Chemical plants often handle highly corrosive media like sulfuric acid, hydrochloric acid, and nitric acid. PFA ensures equipment remains corrosion-free and leak-proof long-term.
High-temperature insulation cables for aerospace and military equipment
Data communication cable jackets
Heating cable protective layers
Why choose PFA? PFA is high-temperature resistant, flame retardant (UL94 V-0), and electrically stable—reliable even in harsh environments.
Medical device components, catheters
Pharmaceutical equipment linings (won't contaminate drugs)
Laboratory器具
Why choose PFA? PFA meets FDA food-grade requirements, won't react with drugs, and won't leach harmful substances.
| Market | Characteristics | Demand for PFA |
|---|---|---|
| India | Rapidly developing semiconductor and chemical industries | Strong demand for high-purity pipes, valves, tank linings; PFA coating market growing at 20.84% annually |
| Italy | Important chemical equipment manufacturing base in Europe | Growing demand for high-end PFA pipes, chemical equipment linings, injection-molded parts |
PFA can be formed using common plastic processing methods. Here are key parameters:
| Processing Method | Temperature Settings | Typical Products |
|---|---|---|
| Injection Molding | Barrel 330-370°C, Mold 180-230°C | Wafer boxes, valves, pipe fittings |
| Extrusion | Barrel 310-350°C, Die 340-365°C | Pipes, wire jackets |
| Compression Molding | 340-360°C, Pressure 10-30MPa | Tank linings, sealing gaskets |
| Rotational Molding | 350-370°C | Irregular tanks, complex linings |
Processing Tips:
PFA processing temperature should not exceed 380°C to avoid decomposition and harmful gas release
Recommend drying at 100-120°C for 4 hours before processing (remove moisture)
Mold shrinkage approximately 1.5-3.5%—allow extra space when designing molds
