Teflon™ Coatings Resources

 

The unique combination of properties inherent to all Teflon™ coatings make them a natural choice in a number of industries. The tables below break down the Thermal, Mechanical, Electrical, and Chemical properties of the four primary product lines of Teflon – PTFE, FEP, PFA, and ETFE.

Featured Teflon Coating Lines

PTFE – Polytetrafluoroethylene

PTFE nonstick coatings are two-coat (primer/topcoat) systems. PTFE products have the highest operating temperature of any fluoropolymer (500°F/260°C), an extremely low coefficient of friction, good abrasion resistance, and good chemical resistance.

FEP – Fluorinated ethylene propylene copolymer

FEP nonstick coatings melt and flow during baking to provide nonporous films with excellent chemical resistance. FEP coatings have very low friction and excellent nonstick coating properties, with a maximum use temperature of 400°F/204°C.

PFA – Perfluoroalkoxy

Like FEP, PFA nonstick coatings melt and flow during baking to provide nonporous films. PFA’s properties include a higher maximum use temperature of 500°F/260°C and improved toughness making it an excellent choice for a wide variety uses, especially those involving chemical resistance.

ETFE –Copolymer of ethylene and tetrafluoroethylene

Although not fully fluorinated, ETFE coatings have excellent chemical resistance and can operate continuously at 300°F/149°C. This resin is the toughest of the fluoropolymer coatings and can be applied at film builds up to 2,000 micrometers (80 mils).

Primary Teflon Coating Properties

Thermal Properties of Teflon Coatings

Teflon fluoropolymer coatings can operate continuously at temperatures up to 550°F/290°C and can be used intermittently to 600°F/315°C with adequate ventilation. The table below outlines those Max Use Temperatures as well as Flame Rating, Limiting Oxygen Index, and Thermal Conductivity, among others.

Teflon Coatings: Mechanical Properties

Teflon nonstick coatings are both hydrophobic and oleophobic as well as very resistant to scratches and abrasion due to their excellent durability and toughness. The table below provides data on Hardness, Coefficient of Friction, Abrasion Resistance, Specific Gravity, and Tensile Strength, among others.

Teflon Coatings: Electrical Properties

Over a wide range of frequencies, Teflon fluoropolymers have high dielectric strength (typically 2000 V/mil), low dissipation factor and very high surface resistivity. Data for these properties as well as dielectric constant, arc resistance, and volume resistivity are outlined below.

Teflon Coatings: Chemical Resistance Properties

Teflon coatings are normally unaffected by chemical environments and are great anti-corrosion coatings. Below, find data on Chemical/Solvent Resistance, Water Absorption, Salt Spray Resistance, Detergent Resistance and Weather Resistance (Florida Exposure).
