Chemical resistance of pipes and pipe components made of polypropylene.
POLMELT PP-R pipes and pipe components are extremely durable products that are not only easy to process, but are also characterized by high strength under internal pressure and temperature stress, they are corrosion-resistant and chemically very resistant. We have compiled a compact overview of their resistance and the chemical stresses for which they are suitable.
This overview in tabular form applies to polypropylene pipes and pipe components intended for the transport of the flow materials listed in the tables. It must be taken into account that each application involves a wide variety of variables in the operating conditions. For this reason, this chart is only a guide to the chemical resistance of our polypropylene piping systems and pipe sections. An assessment of the suitability of pipes and pipeline components for a flow substance, defined as chemical suitability (for term see DIN 53 756), can only be made on an individual basis. We would be pleased to check your application for you.
