Polypropylene Fiber (PP Fiber)

Chemical Formula: (C₃H₆)ₙ  

CAS No.: 9003-07-0  

Melting Point: 160-170°C  

Density: 0.91 g/cm³  

Color: Natural white (custom colors available)

Polypropylene Fiber (PP Fiber) is a high-performance synthetic fiber made from isotactic polypropylene polymer. It is widely used as a secondary reinforcement material in construction, geotechnical, filtration, and textile applications due to its excellent crack resistance, corrosion resistance, and dispersion properties.

Key Benefits

Crack Control: Reduces plastic shrinkage cracks in concrete by up to 70%

Impact Resistance: Improves toughness by 20-30% compared to plain concrete

Corrosion Proof: Immune to chloride/chemical attack (ideal for marine environments)

Uniform Dispersion: Hydrophilic coating prevents balling during mixing

Lightweight: Adds negligible weight (0.91g/cm³ density)
