PFA coatings are useful in a wide variety of industries. Medical instrument manufacturers, agricultural machinery and food processing manufacturers, as well as semiconductor, aerospace, and chemical engineering professionals all rely on PFA coating services.
What is PFA?
PFA is a co-polymer product of PTFE. It is applied electrostatically in powder form and cured at between 650 and 775 F. PFA is hydrophobic and oleophobic, and possesses excellent dielectric strength (3000 volts/mil).
Here are the top 5 benefits of PFA coatings:
- Chemical resistance.
PFA melts and flows during curing, providing a non-porous film. This makes PFA incredibly impervious to chemicals, providing an idea coating for pumps, tanks, and vessels used in the chemical industry.
- Superior release properties.
PFA is a superior choice as a mold release agent because very few substances will adhere to it. PFA is very slippery, with a coefficient of friction of 0.10 against polished steel.
- Outstanding temperature resistance.
PFA is resistant to 500 F continuous. Additionally, PFA possesses good cryogenic stability, and can withstand temperatures as low as -310 F with no significant loss of physical properties.
- High abrasion resistance.
PFA is a thermoplastic and builds up significantly thicker than other fluoropolymers. This offers greater toughness than PTFE or FEP coatings. PFA is also available in an Ultra-Durable formulation.
- FDA approvability.
Most PFA coatings conform to FDA Regulation 175.3, and are frequently used on medical instruments and in food processing applications. PFA is ideal for pharmaceutical equipment, laboratory equipment, food processing machinery, and cookware and bakeware.
