Comparison of the properties of PP and PVC materials
Thread Content
Experts, does anyone have data comparing the material properties of PVC and PP in various aspects? Could you share it? Which is better for emergency valves using hydrochloric acid: PP or PVC? If available, could you please send it to the email ws1451411@sina.com?

It is recommended to purchase a high-quality PP valve, preferably one made by manufacturers such as GF or AGRU; such valves can last for 10 years in indoor use without failing
