Description

Poly[Tetrafluoroethylene-Co-Perfluoro (Alkyl Vinyl Ether)] is a high-performance fluoropolymer, commonly known as PFA, which combines the excellent chemical resistance of PTFE with enhanced melt-processability. This material is critical for applications demanding extreme purity, thermal stability, and non-stick properties in highly corrosive environments. It is an essential engineering plastic for the semiconductor, chemical processing, pharmaceutical, and high-purity fluid handling industries.

Application

• Semiconductor Manufacturing: Critical components for wafer processing, including liners for chemical vessels, tubing, fittings, and wafer carriers, where ultra-high purity and resistance to aggressive etchants and cleans are paramount.
• Chemical Processing Equipment: Lining for reactors, tanks, and pipes; seals, gaskets, and bellows for handling highly corrosive acids, bases, and solvents at elevated temperatures.
• Pharmaceutical & Bioprocessing: Single-use bioprocess bags, tubing, connectors, and filter housings that require sterilization (autoclave/SIP), leachables control, and compliance with stringent regulatory standards.
• Wire & Cable Insulation: Primary insulation for high-temperature, high-frequency, and demanding environmental applications due to its excellent dielectric properties and flame resistance.
• Food & Beverage Industry: Non-stick coatings for processing equipment, release sheets, and components that require FDA-compliant materials with easy-clean surfaces.
• Analytical & Laboratory Equipment: Labware, beakers, stir bars, and chromatography system components that demand chemical inertness to prevent sample contamination.

Quality Control

Our PFA products are manufactured under strict quality management systems to ensure batch-to-batch consistency and performance reliability. We provide comprehensive quality documentation, including Certificates of Analysis (COA) detailing key parameters such as melt flow rate, thermal stability, and purity. Materials can be supplied in compliance with relevant industry standards for semiconductor (SEMI), pharmaceutical, and food contact applications. Custom specifications and purity grades are available to meet specific project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flames. Although chemically stable, prolonged exposure to direct sunlight or UV radiation should be avoided to prevent any potential surface degradation.
