Polypropylene in the construction industry


[edit] Introduction

Polypropylene (PP, also known as polypropene or polymerised propene) is a type of thermoplastic polymer resin that has similar qualities to polyethylene (PE) but is slightly harder and has better resistance to heat and organic solvents. After PE, polypropylene is the second-most widely produced commodity plastic with a global market (2013) of around 55 million tonnes.

A member of the polyolefin family of resins, PP can be injection moulded and extruded into many shapes and products such as cups, cutlery, containers, housewares and car parts e.g batteries. It is also spun into fibres for inclusion in industrial and domestic textiles, including for clothing.

As a plastic it is extremely versatile and found in common household items and used in both commercial and industrial applications.
