The global demand for polypropylene generated an annual market of approximately 74 million metric tons in . Around 30 per cent of this was consumed by the packaging industry. The electrical and equipment manufacturing industry is also a major player, consuming around 15 per cent of the market. The annual figure is forecasted to grow to around 90 million metric tons by the year .

Polypropylene is known as the &#;steel of plastics&#; because it has several properties that can be modified to tailor to specific applications. Polypropylene fibres and powders are heavily used in the automotive industry, packaging, fashion, sports, medical, and housewares.

Polypropylene is the second most used plastic in the world, so the demand for high-quality polypropylene fibres and powders is high, and there are many advantages to using them, including:

1. Polypropylene is Resistant to Fatigue 

Polypropylene fibres and powders help manufacture things like car tires, conveyor belts, and ropes because its resistant to fatigue, wear and tear, ensuring products stand the test of time.

2. Low Density 

Polypropylene is a very light plastic, which makes it ideal for products that need to be lightweight but strong, such as car bumpers. Polypropylene is also used for boat parts and other recreational vehicles because of its low density.

3. Chemical Resistance 

Polypropylene is resistant to many chemicals, making it an ideal material for containers that will hold aggressive fluids like acids and alkalis.

4. Recyclability 

Polypropylene can be recycled multiple times without losing any of its properties, making it a sustainable choice for many applications.

5. A Non-Toxic Solution 

Polypropylene is a non-toxic plastic, so it&#;s safe to use for packaging and other items that come into direct contact with people.

6. Polypropylene Has No Static Electricity 

Polypropylene fibres and powders do not accumulate static electricity, so they&#;re often used in electronic applications to prevent damage from static discharge.

7. Low Moisture Absorption 

Polypropylene doesn&#;t absorb moisture, so it&#;s often used in food packaging to keep products dry. You&#;ll also find polypropylene in things like rain gear and outdoor furniture covers because of its water-resistant properties.

8. Polypropylene is Translucent 

This property is beneficial for products that need to be see-through, such as polypropylene containers for storing liquids.

9. Non-Polar 

Polypropylene is a non-polar material, meaning it does not readily absorb water or other liquids, making it ideal for use in laboratory equipment, containers, and pipes.

10. Tough, Flexible and Durable 

Polypropylene fibres and powders will help toughen up a product and make it more flexible and durable without adding too much weight. This is why polypropylene is often used in the automotive industry.

11. Affordable and Cost-Effective 

The cost of polypropylene is lower than other plastics with similar properties, making it a popular choice for mass-produced products. Due to possessing several advantageous properties, polypropylene is made to last and withstand a variety of applications, making it very cost-effective.

Polypropylene is an extremely versatile plastic with many advantages, which is why it is one of the most popular plastics in the world. It&#;s also a popular material for nonwovens, such as filters, nappies, sanitary towels, medical mesh, and face masks.

Polypropylene is an excellent choice if you are looking for a strong, lightweight, and dimensionally stable plastic. Polypropylene fibres and powders can be used in a variety of industries and applications to create high-quality products.

Applications and advantages of using polypropylene fibres

Applications and advantages of using polypropylene fibres.

Polypropylene fibres have certain features that make them an ideal complement to achieve specific advantages when used for building works, more specifically, when added to concrete.

They mainly comprise continuous or discontinuous polypropylene fibres arranged within a plastic matrix. Below are some of the reasons why polypropylene is used as a reinforcement material:

• Good value for money.
• Versatility: compatible with most existing processing techniques and used in different applications.
• Because they are the plastic material with the lowest specific weight, lower amounts of material are required to obtain the finished product.
• Mechanical properties: polypropylene can achieve a good impact/stiffness balance.
• Chemical properties: excellent chemical resistance to common solvents.
• Good dimensional stability when exposed to high temperatures.
• Vapour barrier: prevents the transfer of moisture.

Polypropylene fibres are used in the following applications:

• Industrial pavements.
• Highly resistant concrete. Industrial grounds.
• Tunnels.
• Roads.
• Special mortars.
• Precast concrete.

Among the advantages of using polypropylene fibres for reinforcement purposes are:

• More cost effective, fast and easy to use alternative to mesh as a reinforcement method.
• Reduces the formation of retraction and contraction cracks.
• Saves time during the construction process as it can be applied directly after combining with concrete.
• Lower labour costs due to requiring less steps during the execution of the building works.
• Provides a secondary, uniform reinforcement.
• Easy to mix with concrete at both on site and at the manufacturing plant.
• Non corrosive and non magnetic material.
• Provides added tenacity to structures.
• Increased  impact resistance while preventing erosion.
• Provides safety at building works.
• Provides 3D strengthening.
• High traction resistance.
