Polypropylene Fiber

PP Fiber with polypropylene as its raw material, this fiber is produced by
special technology. The products have net-like structure with many fiber
monofilaments.
Product Description
Polypropylene fiber/ PP fiber, also known as anti-cracking fiber, PP fiber, or
concrete fiber, is a high-strength bundled monofilament fiber made of
polypropylene. The addition of our polypropylene fiber products to mortar or
concrete can effectively control the micro-cracks of concretes or mortars
caused by plastic shrinkage, dry shrinkage, temperature changes, and other
factors, etc. At the same time, it can also prevent and inhibit the formation
and development of cracks, thereby significantly improving the penetration
resistance, impact resistance, and earthquake resistance of concretes.
Our polypropylene fiber products have tensile strength and high modulus, which
can help enhance the mechanical properties of high-strength concretes and
improve the bond strength between fibres and cementitious matrix. It has
excellent dispersibility and will not agglomerate, thus ensuring its effective
anti-cracking performance.
Advantages of Polypropylene Fiber
Polypropylene is a light fiber, its density (.91 gm/cm³) is the lowest of all
synthetic fibres.
It does not absorb moisture. This means the wet and dry properties of the fibre
are identical. 
The thermal conductivity of PP fibre is lower than that of other fibres and may
be used in applications as thermal wear.
