Which is more resistant to chloride corrosion, RPP or PTFE?

I was confused about choosing the internal material for the pump; the fluid flowing through it is 10% PAC. I thought PTFE would offer better corrosion resistance, but when I asked for quotes, RPP turned out to be more expensive.

Then use a pump with PTFE lining; it has excellent resistance to chloride ions

Fluoroplastic or fluorine-lined pumps can fully meet the requirements; our company uses diaphragm pumps. By the way, you mean PPR, right?

For resistance to chloride ions, PTFE will meet the requirements

It’s definitely not PPR; it’s RPP, which is reinforced polypropylene
