Fluoropolymer coatings are specialized plastic coatings made from fluorinated polymers that provide non-stick, low-friction, and highly chemical-resistant surfaces. These coatings form a thin, durable film that protects metals, plastics, and composites in demanding environments.
Key Characteristics:
- Low Surface Energy: Resists sticking, fouling, and buildup.
- Chemical Resistance: Inert to most acids, bases, and solvents.
- Thermal Stability: Performs in high-temperature environments, often up to 500°F (260°C) or higher.
- Lubricity: Reduces friction, even under dry conditions.
Common Fluoropolymer Types:
- PTFE (Teflon®) – Excellent non-stick and temperature resistance.
- FEP & PFA – Offer greater flexibility and chemical resistance.
- ETFE & PVDF – Used for electrical insulation and corrosion resistance.
Applications:
-
- Cookware: Non-stick pans and bakeware.
- Industrial: Pumps, valves, fasteners, and molds.
- Automotive & Aerospace: Wire coatings, gaskets, and anti-corrosion parts.
- Electronics: Protective layers on semiconductors and sensors.
Popular fluoropolymer coatings include Xylan®, Teflon®, and other engineered blends designed for food-grade, medical, and industrial performance.
