Comparing summary
of properties of various coating systems:
| PTFE: |
- Lowest friction coefficient
- High creep resistance
- Not processable by thermoplastic means
- High chemical resistance
- Temperature resistance from -200°C to approx. +260°C
|
| PFA: |
- Similar properties like PTFE, but thermoplastic processing possible
- high creep resistance
- high chemical resistance
- temperature resistance from -200°C to approx. +260°C
- good anti-adhesion property
|
| FEP: |
- Chemical resistance similar to PTFE
- mechanical resistance less than PFA and PTFE
- temperature resistance from -200°C to approx. +205°C
- even better anti-adhesion effect than PFA
|
| ETFE: |
- Highest chemical resistance behind PTFE, PFA and FEP
- same elongation property as PTFE
- temperature resistance from -100°C to approx. +155°C
- highest impact toughness of all plastic materials
- high modulus of elasticity
- coating thicknesses up to 800 µm max.
|
| E-CTFE: |
- Resistant to organic solvents, strong acids, chlorine and sodium hydroxide
- high impact toughness down to -40°C
- temperature resistant from -100°C to approx. +150°C
- regular coating thickness 800 µm, maximum coating thickness possible 1500 µm
|
| Slide paint coat: |
- Non-porosity
- high sliding capability, expecially as a counterpart to PTFE
- Strong adhesion to underground
- temperature range up to approx. 130°C
- coating thicknesses from 150 µm to 300 µm
- high hardness, Shore D DIN 53505 = 90-95
