Advantages:

1. Excellent Corrosion Resistance: PFA exhibits outstanding chemical stability, resisting nearly all corrosive substances, including strong acids, alkalis, and organic solvents.
2. Exceptional High-Temperature Resistance: PFA remains stable across a temperature range of -200°C to 260°C, making it suitable for harsh high-temperature environments.
3. Superior Transparency: PFA offers better transparency than PTFE, enabling visual inspection and fluid observation.
4. Smooth Surface and Low Friction Coefficient: PFA has excellent non-stick and self-lubricating properties, reducing friction and preventing debris adhesion.
5. Excellent Electrical Insulation: PFA is an ideal high-frequency insulating material due to its superior electrical insulation properties.
6. Aging and Weather Resistance: PFA is stable in atmospheric conditions, with strong anti-aging capabilities, suitable for outdoor and extreme applications.
7. Strong Processability: PFA has good melt flow characteristics, suitable for injection molding, extrusion, and various processing methods.
8. Biocompatibility: Due to its physiological inertness, PFA can be used in pharmaceuticals, medical devices, and the food industry, meeting FDA and other international standards.
9. Permeation Resistance: PFA has low permeability, offering excellent performance in gas barriers and liquid sealing.

FAQ

1. What are the advantages of PFA-coated products?

PFA coatings offer outstanding non-stick properties, high chemical resistance, and the ability to withstand extreme temperatures (-200°C to 260°C). These coatings are also known for their durability, smooth finish, and excellent electrical insulation.

2. How is PFA different from PTFE in coatings?

While both PFA and PTFE provide strong non-stick and chemical-resistant properties, PFA has a slightly higher melting point and superior transparency, making it suitable for applications that require visual inspection. Additionally, PFA’s melt processability allows for thicker, more uniform coatings.

3. In what applications are PFA-coated products commonly used?

PFA-coated products are widely used in industries such as:

• Chemical processing (tanks, pipes, valves)
• Food and beverage (non-stick baking trays, molds)
• Medical and pharmaceutical (coatings for lab equipment)
• Electronics and semiconductors (coated components for high purity)

4. What thickness options are available for PFA coatings?

Standard PFA coatings range from 25 to 150 microns (0.025-0.15 mm), but can be applied up to 500 microns (0.5 mm) for applications requiring enhanced durability.

5. How should I care for and clean PFA-coated surfaces?

PFA-coated surfaces are easy to clean due to their non-stick properties. Mild detergent and warm water are usually sufficient. Avoid using abrasive cleaning tools or harsh chemicals that may damage the coating.

6. Are custom thicknesses and colors available for PFA coatings?

Yes, custom thicknesses and colors are available based on application requirements. For specific needs, please contact us to discuss customization options.

7. Can PFA-coated products be used in high-temperature applications?

Yes, PFA coatings are ideal for high-temperature applications, with a continuous operating range up to 260°C and short-term exposure up to 300°C.

8. Are PFA coatings safe for food contact?

Yes, high-quality PFA coatings are FDA-approved and suitable for direct contact with food. They are widely used in food processing and baking equipment.
