CHEMICAL COMPATIBILITY
The type of liquid, temperature and working environment are factors to be considered when deciding on the best choice of construction materials for the pump and its correct chemical compatibility. The table below gives some examples of the most commonly-used substances:
| SUBSTANCE | PP | ECTFE (Halar®) |
PTFE (Teflon®) |
PPS-V (Ryton®) |
FPM (Vyton®) |
Santoprene® |
|---|---|---|---|---|---|---|
| Acetaldehyde | A1 | D | A | A | D | --- |
| Acetamide | A1 | C | A | A | B | --- |
| Vinyl acetate | B1 | A2 | A2 | --- | A1 | --- |
| Acetylene | A1 | A | A | A | A | --- |
| Vinegar | A | B | A | A | A | --- |
| Acetone | A | D | A | A | D | A1 |
| Fatty acids | A | A | A | --- | A | D |
A = very good
B = good
C = poor, not recommended
D = severe etching, not recommended
- = information not available
1 = satisfactory up to 22°C (72°F)
2 = satisfactory up to 48°C (120°F)
