Fluoropolymer Coating Types

Comparative summary of characteristics of common fluoropolymers that Maksem uses are as follows.  Prominent features of each material are underlined.

PTFE (Poly tetra-fluoro ethylene)

Lowest coefficient of friction

- High creep resistance

Thermo-plastically unprocessable

- High chemical resistance

- Temperature resistance from -200°C to +260°C


PFA (Perfluoroalkoxy)

- Similar characteristics like PTFE, but thermo-plastically processable

- High creep resistance

- High chemical resistance

- Temperature resistance from -200°C to +260°C


FEP (Fluorinated ethylene proplylene)

- Chemical resistance similar to PTFE

- Mechanical resistance lower than PTFE and PFA

- Temperature resistance from -200°C to +205°C

Better non-stick properties than PFA

ETFE (Ethylene tetra-fluoro ethylene)

- Highest chemical resistance after PTFE, PFA and FEP

- Same expandability as PTFE

- Temperature resistance from -100°C to +155°C

Highest impact strength of all plastics

- High E module

Layer thickness up to 800µm max.

E-CTFE (Ethylene chloro tri-fluoro ethylene)

- Resistance to organic solvents, strong acids, chlorine and sodium hydroxide

- High impact strength

- Temperature resistance from -100°C to +150°C

- Nominal layer thickness 800µm, maximum layer thickness 1500µm
