Polypropylene pipe materials are non-toxic, hygienic, with good heat resistance, and also resistant to most solvents and organic chemicals. With excellent processing performance, they can effectively reduce the scrap rate and energy consumption, thus widely used in hot and cold water pressure-resistant pipes, floor heating pipes, urban drainage pipes, plate profiles, and other fields.
1. Good heat resistance, can be used for a long time under 95°C.
2. They can resist most solvents and organic chemicals.
3. With excellent processing performance, they can effectively reduce the scrap rate and energy consumption.
They can be used in hot and cold water pressure-resistant pipes, floor heating pipes, urban drainage pipes, plate profiles, and other fields.
