Our Filter nozzles and Filter nozzles-stars are made of polypropylene. Depending on the drop in pressure for example at 60 degree Celsius (333 K) Polypropylene (PP) is resistant against:
-
ammonia ag 10%
-
Formaldehyde ag 10%
-
isopropanol all concentrations
-
methanol ag 50%
-
caustic soda solutions 50%
-
hydrochloric acid 50%
-
sulfuric acid 50%
-
soda water
-
ozone 20 degrees Celcius, 50pphm (0,5ml/L)
-
Polypropylene is physiologically unobjectionable.
-
With increasing frost polypropylene gets more sensitive. Please, handle all articles made of polypropylene accordingly. If it is cold we recommend to warm up filter nozzles and nuts before installation.
-
For hot water of a continuous temperature of up to max 135 degrees Celcius depending on the drop in pressure we recommend PVDF. (Conditionally resistant to concentrated caustic solutions).
