WHAT IS POLYPROPYLENE?
Polypropylene is a durable synthetic resin that is a polymer of propylene. It’s particularly useful for making molded and extruded objects, including pipes and fittings. There are two different kinds of polypropylene used in pressurized pipe-making: polypropylene random copolymer (PP-R) and polypropylene random copolymer with modified crystallinity and temperature resistance (PP-RCT). Of the two, PP-R is the more common and broadly useful.
PP-R is a high-temperature plastic pressure piping system first used for plumbing and hydronic heating in the 1980s in Europe. PP-R piping products are rated for continuous operation at 180ºF (82Cº) temperature, with pressure ratings dependent on their wall type (SDR). PP-R pipes commonly include reinforcement layers for benefits such as reducing longitudinal thermal expansion/contraction.
PP-R pipes provide resistance to highly acidic and basic solutions, making them ideal for a wide range of applications. Common uses include HVAC piping, outdoor piping, industrial piping, plumbing, and food-grade piping. PP-R joints are heat-fused, not glued. Their high-heat and/or pressure performance makes PP-R pipes suitable for demanding applications, such as pressure piping (plumbing, hydronics) in commercial high-rise buildings.
