Corrosion resistance of PPR pipes
Thread Content
It’s unclear what the corrosion resistance of PPR is like Who has information on this topic? Please learn more: handshake:handshake:handshake
The corrosion manual only covers PP material; PPR is not explicitly addressed.
PP is polypropylene, while PPR is a type of modified polypropylene; its full name is terpolymerized random copolypropylene. During the modification process, an appropriate amount of PE material is added to PPR, around 5-10%； Another key difference is that the molecular structures are different ； In terms of performance, it offers greater flexibility compared to PP, reducing the weakness of brittleness at low temperatures; at the same time, its stiffness is also lower than that of PP.
