PFA COATINGS

PFA (Perfluoroalkoxy) coatings are advanced fluoropolymer coatings known for their high-temperature stability, excellent chemical resistance, and non-stick properties. PFA coatings are used in industries such as pharmaceuticals, food processing, and chemical processing, where resistance to extreme environments is crucial.

Characteristics

High Chemical Resistance
Offers excellent resistance to a wide range of chemicals.
High Temperature Resistance
Withstands extreme temperatures without losing performance.
Low Friction Surface
Ensures a low-friction surface, reducing wear and tear.
Non-Stick Properties
Provides a smooth, non-stick surface ideal for various applications.
Good Mechanical Strength and Flexibility
Combines strength with flexibility for versatile use.
Temperature Range
PFA coatings offer outstanding performance across an extensive temperature range, maintaining their properties in both high and low temperatures.

  • Service Temperature: 320°F to 500°F (-195°C to 260°C)
  • Melting Point: 305°C (581°F)
Coating Thickness
PFA coating thickness can vary based on the specific needs of the application. Common thickness options include:

  • Standard Thickness: 0.3 mm – 1.5 mm
  • Application-Specific Thickness: up to 2 mm (available on request)

The coating thickness is chosen based on the exposure to chemicals, abrasion, and temperature conditions.
