Polypropylene fiber is a synthetic fiber made from polypropylene resin. It is lightweight, stable, and non-corrosive. It is widely used in concrete, mortar, plaster, and many cement-based products to improve crack control and surface durability.<\/p>\n\n\n\n

This article explains what a polypropylene fiber is, how it works in cement mixes, where it is used, and what you should watch out for when choosing dosage or suppliers.<\/p>\n\n\n\n

What is a polypropylene fiber<\/a>?<\/h2>\n\n\n\n

Polypropylene fiber is a man-made fiber produced from a thermoplastic polymer called polypropylene (PP). It does not absorb water. It does not rust. It stays stable in most cement environments.<\/p>\n\n\n\n

In construction, polypropylene fiber is usually sold as short cut fibers. You add them into the mix during batching. The fibers spread through the paste, then form a small “net” inside the hardened product.<\/p>\n\n\n\n

What does polypropylene fiber look like?<\/h2>\n\n\n\n

Polypropylene fiber can look very different based on its type. The two most common categories are micro fiber and macro fiber.<\/p>\n\n\n\n
