Enhance Building Materials with Premium Polypropylene Short Fiber

PP Fiber & Pure Polypropylene Fiber

Polypropylene Fiber（PP Fiber） is a synthetic fiber made from polypropylene, a type of polymer known for its strength, durability, and resistance to various chemical and environmental factors. This fiber is widely used in construction, textiles, and other industrial applications due to its excellent performance characteristics.

Main features of Polypropylene Fiber(PP Fiber)

High Strength and Durability:

Polypropylene short fibers are known for their high tensile strength and durability, which make them suitable for applications requiring resistance to physical stress and wear.

Chemical Resistance:

These fibers exhibit excellent resistance to a wide range of chemicals, including acids, alkalis, and organic solvents. This chemical stability makes them ideal for use in environments where exposure to harsh substances is common.

Melting Point:

Approximately 160-170°C, providing good thermal stability.

Lightweight:

Polypropylene fibers are inherently lightweight, which contributes to the overall reduction in weight of the composite materials or products in which they are incorporated. This feature is particularly beneficial in the automotive and aerospace industries, where weight reduction is a key consideration.

Moisture Resistance:

PP short fibers do not absorb water, making them ideal for outdoor applications and in products where moisture resistance is critical. This property also contributes to their mold and mildew resistance.

Low Cost:

Compared to many other synthetic fibers, polypropylene short fibers are relatively inexpensive to produce, making them a cost-effective choice for many applications.

Eco-Friendly:

Polypropylene fiber is recyclable, contributing to sustainable practices in industries.

Fibre cutting site

Synthetic polypropylene fibres can be supplied in the lengths required by the customer.

Applications of PP Fiber Pure Polypropylene Fiber

Concrete Reinforcement：

When added to concrete, polypropylene short fibers help to reduce the formation of cracks during the curing process and increase the tensile strength of the material. This reinforcement leads to more durable and resilient concrete structures, capable of withstanding environmental stresses and extending the lifespan of buildings and infrastructure.

Industrial Flooring:

In industrial flooring applications, PP fibers increase the impact resistance and durability of concrete surfaces, making them ideal for warehouses, manufacturing facilities, and other high-traffic areas.

Asphalt Modification：

Incorporating PP short fibers in asphalt mixtures enhances the thermal stability and fatigue resistance of roads and pavements. This results in improved resistance to cracking and rutting, especially under heavy traffic conditions or extreme temperatures, thereby prolonging the pavement lifespan and reducing maintenance costs.

Mortars and Stucco:

Adding PP fibers to mortar and stucco formulations increases their flexural and tensile strength, reduces the likelihood of cracking, and improves the overall performance of the finished surface.

Can Polypropylene Short Fiber replace steel reinforcement?

Polypropylene short fiber cannot fully replace steel reinforcement in all applications. However, it is an excellent supplementary reinforcement, reducing the amount of steel mesh or rebar required in many cases. It helps control shrinkage cracks and improves overall material performance, particularly in non-structural applications.

Is Polypropylene Short Fiber safe and environmentally friendly?

Yes, polypropylene short fiber is non-toxic, chemically inert, and recyclable. It does not emit harmful substances and is safe to handle, making it an environmentally friendly option for construction projects.

Can Polypropylene Short Fiber be used in all types of concrete?

Yes, polypropylene short fiber is compatible with most types of concrete and cement-based materials. It can be used in standard, high-performance, and lightweight concrete mixtures, as well as in precast products, shotcrete, and industrial flooring.

What are the advantages of using Polypropylene Short Fiber over other reinforcement materials?

Polypropylene short fiber is lightweight, easy to handle, and cost-effective compared to traditional reinforcement materials like steel. It provides excellent crack control, improves the durability of concrete and mortar, and reduces labor time during the mixing process. Additionally, it is corrosion-resistant, making it suitable for environments where steel reinforcement might degrade.

What is the tensile strength and melting point of Polypropylene Short Fiber?

The tensile strength of polypropylene short fiber ranges from 450 to 750 MPa, depending on the fiber length and type. Its melting point is between 160 and 170°C, ensuring excellent performance in high-temperature environments.

How is Polypropylene Short Fiber packaged and delivered?

At Ningbo Wanhong Ruiquan Technology Co., Ltd., polypropylene short fiber is typically packaged in 20 kg or 25 kg bags, with bulk or palletized delivery options available. Custom packaging solutions can also be provided upon request to meet specific customer needs.
