Definition - What does Polypropylene (PP) mean?
Polypropylene (PP) is a versatile plastic which offers a wide variety of benefits. It is one of the most commonly used plastics in the world, found in everything from automobiles to clothing. Composite pipes made of the thermoplastic polypropylene are used in trenchless construction pipes because of their durability and resistance to corrosion.
Trenchlesspedia explains Polypropylene (PP)
The Polymer Science Learning Center website credits polypropylene with doing double duty as both a plastic and a fiber. As a fiber it can be used in dishes, and as a fiber it can be used in carpets. The versatility of the material extends to a wide variety of industries, including trenchless construction.
Polypropylene is a vinyl polymer, the most common type of plastic. A technical report from Teppfa, Borealis and LyondellBasell claims that polypropylene and polyethylene have the potential for a 100-year service life in gravity sewer pipes. The polymer was first synthesized by a pair of Phillips Petroleum scientists in 1951. The resin identification code “5” appearing on a plastic product signifies the use of polypropylene in its manufacture.
