Conveyants Compatibility
Conveyants Compatibility for Composite Polypropylene Hoses
The lists below offer guidance on the compatibility of our COMPOHOSE® range of polypropylene hoses with various conveyants. Please note that these recommendations are based on chemical compatibility only and are intended as a general guide. The description of a hose as ‘suitable’ does not imply compliance with specific regulations or operating conditions related to the conveyed chemical. It is essential to perform a visual check for internal discolouration if the hose has conveyed a chemical with oxidizing properties, especially before using it for other conveyants where colour contamination is not permissible.
