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 PVDF ECTFE
Halar ®		 EPDM
Dutral ®		 PTFE Teflon ® FPM Vyton ®
Acetaldehyde A1 D A A D
Acetamide A1 C A A B
Vinyl acetate B1 A2 B2 A2 A1
Acetylene A1 A A A A
Vinegar A B A A A
Acetone A D A A D
Fatty acids A A D A A
 

 

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)
