Fluoropolymer Coatings

Fluoropolymers have become an indispensable material for engineers in all market sectors, from food production to the chemical processing industry, thanks to these unique properties:

• Superb long term non-stick
• Superb low friction – Coefficient of friction 0.05-0.12 (ASTMG99)
• Excellent chemical resistance, especially at higher film thicknesses
• High temperature resistance – “In use” temperature up to 260°C, continuous use (290°C intermittent use)
• Low permeation/high corrosion resistance
• All coatings applied are on the FDA positive list for use in food contact applications, Regulation 21 CFR 177.1550 and 21 CFR 177.2440. They also comply with “the materials and articles intended to come into contact with food regulations (EC 1935/2004)”

The original fluoropolymer, PTFE, was discovered in 1938 and is still used widely today. It is now complemented with other perfluorinated polymers such as PFA, FEP, ETFE, ECTFE, etc.
