450MPa Polypropylene Fiber PP Mesh Fibers

450MPa Polypropylene Fiber PP Mesh Fibers 

450MPa polypropylene fiber (PP mesh fibers) are high-strength synthetic fibers made from polypropylene, designed to reinforce concrete and improve its crack resistance. These fibers are characterized by their tensile strength of 450 MPa (megapascals), making them highly durable and effective in enhancing the structural integrity of concrete. 

Key Features of 450MPa Polypropylene Fiber (PP Mesh Fibers) :

◆Polypropylene mesh fiber material: Made from 100% virgin polypropylene, ensuring high quality and consistency.

◆PP mesh fibers tensile strength: 450 MPa, providing excellent reinforcement and crack resistance.

◆Density: Approximately 0.91 g/cm³, making them lightweight yet strong.

◆Length: Typically ranges from 6 mm to 60 mm, with customizable options available.

◆Diameter: Between 20-35 μm, ensuring fine dispersion in concrete.

◆Resistance: Highly resistant to acid, alkali, and corrosion, making them suitable for harsh environments.

◆Melting Point: Around 160-170°C, ensuring stability under normal construction conditions.

Technical Specification

Crack Elongation: 20% ± 5%, ensuring flexibility and resilience.

Elastic Modulus: Ranges from 3000-5000 MPa, providing strong  reinforcement.

Polypropylene fiber mesh synthetic fiber function:

◆Improve the impermeability of concrete

◆Improve the cracking resistance of concrete

◆Improve the impact resistance and fatigue resistance of concrete

◆Improve the wear resistance of concrete

◆Improve the plastic deformation ability of concrete

◆Strong acid and alkali resistance, with good stability

◆Improving the homogeneity of concrete

Applying instruction:

◆The choices of polypropylene pp fiber mesh length:Generally,the length of polypropylene pp mesh fiber in engineering concrete is 20mm.

◆The amount of polypropylene mesh fiber is 0.9KG, and the amount of waterproof layer on the bridge floor is 1.8KG, and the amount of other materials is not changed. When there are special uses, the amount of polypropylene mesh fiber can be determined by testing.

◆Mixing process:crusted stones,fibers and sands are put into the mixer in succession.After stirring for two minutes,fiber will fully spread and then add cement and water and stir normally.The addition of materials also can be put into as usual,but the stirring time should be properly prolonged to more than 4 minutes make fiber completely mixed.

◆Mixer:Horizontal Two-shaft Forced Mixer.

Polypropylene fiber mesh packaging:

1、Typically packed in 600g or 900g bags,may packed as customer’s requirement.

Polypropylene fibers pp mesh fiber  application:

polypropylene fiber concrete fibers are widely used in various construction and infrastructure projects  such as: 

◆Projects like concrete road, bridge and factory floor which strictly require cracking resistance.

◆Concrete pavament, deck, airport runway,factory horizon,shortcrete projects

◆Such as tunnel,mine wall,roof,reservoir and other projects using special construction methods.

◆Irrigation work such as river,dam

◆PP mesh fiber can be used in large projects .such as terminal revetment,bridge pier

◆Polypropylene fibers pp mesh fiber can be used as concrete precast.
