Polypropylene Twisted Bundle Fiber Description

Polypropylene twist/bunch fiber can be used instead of steel fiber for reinforcement in cement concrete.

Compared with steel fiber, it has the advantage of easy dispersion and blending, no damage to the mixing equipment, etc

The rigid polymer fiber is made from polypropylene and features a rough surface treatment produced by a special parallel-thread extruding & twisting process. It has high break strength, better dispersion, and strong

combining ability, and will be widely used instead of steel fiber to reinforce the cement concrete and make it crack-resistant.

Polypropylene Twisted Fiber Main Technical Specification

Density(g/cm3)	0.91 +/- 0.01	Raw material	PP
Length(mm)	20,30,48,50, 54mm	Equivalent Dia(mm)	0.3±0.05
Shape	twisted	break tensile Ratio(%)	8-15
Crack Ratio	20+/-5 %	Melting point ( C. Deg)	160-170
Tensile Strength	>500 MPa	Water absorbency	NO
Elastic Modulus (MPa)	>3500	Resistance to acid & alkali	strong

Recommended adding 2.0–3.0 kg of fiber per cubic meter of concrete, depending on the application.

Polypropylene Twisted Fiber Applying Instruction

1. Ratio design of the fiber concrete:
Generally, the recommended amount to add to the concrete is more than 2.7kg per sqm ( volume ratio is 0.3% ), reinforcement

adding amount is 5.5 kg. Compared with adding 47kg of steel fiber, 5.4 kg of polymer fiber has the same volume ratio to the concrete.

2. length:

48, 50, or 54mm for common crack-resistant requirements.

3. Matching Ratio:

Usually, there is no need to change the concrete's matching ratio.

Considering the requirement of fissure-resistant, the polymer fiber

is recommended to be combined with the polypropylene fiber mesh

the volume ratio of 1:1 (0.9 kg fiber mesh per sqm of cement concrete).

4. Mixer Adoption: Double-axle horizontal compelling mixer is a priority.

5. Mixing process:

Crushed stones, fibers, and sands are put into the mixer in succession.

After stirring for two minutes, the fiber will fully disperse; then add cement and water, and stir as usual. The addition of

materials also can be put into as common concrete, but the stirring time should be properly prolonged to make fiber completely

Mixed.

6. Shaping & Maintenance

There is no special requirement; it may be vibrated for 30 s. The maintenance of fiber concrete should be done the same way as for

normal concrete.

7. Package: 1kg or 0.9kg per bag in common, 10kgs per carton.

May be packed as per customer requirements; water-soluble bag is also available.

Polypropylene Twisted Fiber vs Steel Fiber

Items	Polypropylene Twisted Fiber	Steel Fiber
Mixing performance	Easy to mix, no clumping	Hard to disperse, easy to clump
Equipment wear	No damage to mixing machines	Causes serious wear on equipment
Corrosion resistance	Never rusts, works well in wet & salty environments	Prone to rust over time
Weight	Lightweight, adds little extra load	Heavy weight
Construction safety	No sharp edges, safe for workers	Has sharp edges, easy to cause injuries
Cost	Cost-effective	Higher price
Reinforcement effect	Good for anti-crack, impact resistance & toughening	Higher strength, ideal for extremely heavy-load projects

RFQ

1. Q: Is the fiber corrosion-resistant for wet and salty environments?

A: It resists acid, alkali, and chloride ion erosion, and can work stably for a long time in coastal areas, water conservancy projects,

and damp underground environments.

2. Q: Does the fiber disperse easily during concrete mixing?

A: With a well-designed twisted bunch structure, it can disperse automatically and distribute evenly in concrete without clumping.

3. Q: Can it be used together with other concrete admixtures?

A: It has good compatibility. It can be used with water-reducing agents, air-entraining agents, early-strength agents, and other

common admixtures without affecting their performance.

4. Q: Can you supply custom polypropylene bunch fiber?

A: We provide customization on fiber length and packaging, and produce products in line with clients’ project demands and export

standards.
