Polypropylene fiber

Product Introduction

Polypropylene fiber which is also called engineering fiber, concrete fiber, antl-crack fiber, synthetic fiber, plastic fiber and so on, is a kind of strong fascicular fiber with polypropylene as the main raw material and produced by a special technology. When the fiber is added to concrete or mortar, it can effectively address the problem of micro cracks caused by the shrinkage and temperature fluctuation of concrete(mortar), prevent cracks, Improve the concrete performance in crack resistance, anti-permeabillty, Impact resistance and shock resistance. This fiber is widely used in the pavement of bridge, road and airport runway, mining and tunnel projects, railways, high-rise buildings, slope fixing, fire protection, concrete repair, industrial civil construction Waterproofing works for roofs, walls, basements, pools and roof gardens, insulation and anti-cracklng mortar, various concrete products, etc.

Main function

As a secondary reinforcement material of concrete, Polypropylene fiber can noticeably improve the performance of concrete in crack resistance, anti-permeability, impact resistance, shock resistance, anti-freezing, anti-aging, workability, Pumpability and water-retaining property.
