Polypropylene Fiber is a synthetic fiber made from polypropylene (PP), which is a polymer derived from the polymerization of propylene monomers. It is known for its unique physical and chemical properties, making it widely used in various industries, including construction, textiles, and industrial applications.
Polypropylene fiber is added to concrete as micro-reinforcement, helping to enhance its crack resistance and improve overall strength. It reduces the occurrence of thermal expansion and shrinkage cracking, making it especially useful in extreme temperature environments (both hot and cold).
This makes Polypropylene Fiber a valuable component in enhancing the performance and durability of a wide range of construction materials, offering long-term benefits for both residential and commercial projects.
Chemical Name: Polypropylene Fiber
CAS No.: 65996-61-4
HS Code: 3912 9000
pH: 5.0-9.0
Bulk Density:0.3-0.6 g/cm³
Fiber Length: 200-1,000μm
Appearance: white or black fiber
Lightweight: Polypropylene fiber has a low density, making it lighter than water, which is beneficial for applications where weight is a critical factor.
Chemical Resistance: Polypropylene exhibits excellent resistance to many chemicals, acids, alkalis, and solvents, making it suitable for harsh environments.
Heat Resistance: It can withstand high temperatures, typically up to 150°C, without losing its structural integrity, which makes it ideal for use in high-temperature applications.
Water Resistance: Polypropylene fibers are hydrophobic, meaning they do not absorb water, making them effective in wet or moist conditions.
UV Resistance: Polypropylene has a natural resistance to UV radiation, allowing it to perform well in outdoor and exposed applications.
Abrasion Resistance: Polypropylene fibers are durable and have good resistance to wear and tear, ensuring a longer lifespan in various products.
Timing of Addition: Usually adding during concrete mixing. It can be added directly after sand and gravel aggregates but before water, or simultaneously with water.
Mixing Time: It is recommended to extend the mixing time appropriately (usually 1-2 minutes longer than for ordinary concrete) to ensure uniform dispersion of the fiber in the concrete and prevent clumping.
Dosage: Determined according to project requirements (e.g., crack resistance grade). Generally, the dosage varies from 0.6kg to 1.5kg per cubic meter of concrete.
Construction: After mixing, pour and vibrate according to normal concrete construction procedures. No special curing is required, but should pay attention to the moisture retention curing of conventional concrete.
