PP-R is the abbreviation of Polyethylene Random (copolymer). It can be used for hot & cold water application for transportation of all kinds of liquid food; for piping system in industries like transportation of aggressive fluids (acids chemical, alkalis etc.) and for conveying compressed air. It is also used in agricultural and can be applied to under-floor heating pipes. But the most common use is for drinking water piping system.

Characteristics:
1)Sanitary guarantee & free-poison, green material.
2)Heat resistance.  It can bear up to 80 Celsius for the hot water transportation.
3)Anti-corrosion & anti-scale.
4)Temperature maintenance & energy saving because of its lower heat conductivity.
5)Lightweight and low specific gravity.
6)Aesthetic appearance, smooth wall surface, excellent flow behavior.
7)Flexible, easy for transportation and installation, safe and fast jointing with fusion technology.
8)Excellent stability, long lifespan, more than 50 years under normal conditions.
