Function of Polypropylene Fiber


Crack resistance of concrete

To improve concrete impermeability

To improve freeze-thaw resistance of concrete

Improve impact resistance and toughness of concrete

To improve the durability of concrete


 Application of Polypropylene Fiber 

PP fiber for building can enhance the crack resistance, anti-permeability, anti-abrasion performance, frost-resistance, antiknock and workability of mortar and concrete. Due to the uniform distribution of tens of thousands of fibers in the mortar and concrete, keeping the whole structure strong, avoiding the structure being struck to pieces, preventing the steel from corroding, lengthening the service life of the project and reducing the maintaining cost.

Application Area


Used for crack-resistance putty powder, heat retaining mortar, concrete, building’s surface, wass, ground, pool, undercroft, road and bridge projects.


Advice on Construction


The mixed fibers quantity per CBM mortar for common plastering mortar: 0.9-1.2kg, usually 1kg/m3

The mixed fibers quantity per ton mortar for heat maintaining mortar:1-3kg

The mixed fibers quantity per CBM concrete”0.6-1.8kg, normally 0.9kg/m3


Package of Polypropylene Fiber 

common 0.9 or 1kg per bag. Maybe modified with customer’s requirements.

Q:The difference between polyester and hollow fiber
No analogy, polyester fiber refers to polyester fiber, hollow fiber refers to the processing of fiber form is hollow.
Q:Which material is good, cotton blended or synthetic?
Overall, cotton blends due to synthetic fibers. But the actual needs of different, but also according to the actual needs of the distinction.Clothing fabric, pure natural fiber, natural fiber and chemical fiber blend, purification fiber (man-made fiber) three kinds. Blended fabric is cotton, chemical fiber and other silk, hemp textile products of natural fiber blended yarn fabric.
Q:What is the viscose chemical or natural? Will the ball?
It's not natural fiber. It doesn't matter.
Q:The fabric in the lining is polyester. Can the clothes be machine washed?
Polyester fiber synthetic fiber polyester (polyester fibre) by organic acid and diol which is prepared by spinning the. A large number of industrially produced polyester fibers are made from polyethylene terephthalate, a Chinese product called polyester. It is the largest variety of synthetic fiber at present.
Q:Is Chiffon the same as polyester?
If prices are concerned, polyester Chiffon should be cheaper. The fruiting of polyesters. I hope I can help you.
Q:Will the material be 100% polyester fabric?
Polyester fiber is a chemical synthetic material. It is available in many clothing materials nowadays. It is combined with cotton components in most clothing
Q:Why has the fabric of bamboo fiber shrunk so much?
Bamboo fiber cross section is full of large and small oval pores, can absorb a lot of moisture in a moment, the volume will expand, cool dry because of its fiber characteristics will shrink.
Q:What do you mean by "T300 T700" in carbon fiber?
Carbon fiber T number refers to the level of carbon materials, industry refers to Japan's Dongli company produced a certain kind of carbon material, the industry generally refers to the ultra-high precision carbon materials. How many T refers to the cross section area of 1 square centimeters of the number of units of carbon fiber can withstand tension tonnage. So in general, the higher the T number, represents the carbon level is high, the quality is better.
Q:Will superfine fibers replace pure cotton?
Superfine fibers do not substitute for pure cotton, and two materials are irreplaceable.The definition of superfine fiber is different, also known as micro fiber, fine denier fiber, very fine fiber, the English name microfiber. Generally, the denier 0.3 denier (diameter 5 microns) fiber below is called superfine fiber. Foreign countries have produced 0.00009 denier ultra fine wire, if such a wire pulled from the earth to the moon, its weight will not exceed 5 grams. China has been able to produce 0.13 - 0.3 denier microfiber. The main ingredients of superfine fiber polyester polyester, nylon polyemide two (which is generally 80% domestic polyester nylon 20% and polyester, 100% (water absorption effect is poor, poor hand)).
Q:What are the differences between automotive carbon fiber stickers and films? Who knows the industry, please point out!
There's no such thing as carbon fiber stickers! The so-called carbon fiber stickers, in fact, is the appearance of carbon fiber cloth texture of the film!The film is divided into 2 level and the extension of pressure casting! The superior extension of pressure casting, the specific reason is not to say, as long as know better on the line level casting. At present, there are no more than 10 foundry manufacturers worldwide, and there should be no casting film production enterprises in china.
