Polyester Fiber (PET Fiber)

Polyester Fiber (PET Fiber) - High-Performance Reinforcement Solution

Advanced Synthetic Reinforcement Technology

PET fiber represents a breakthrough in concrete and composite material engineering, offering superior mechanical properties through precisely engineered polymer technology.

Material Science Advantages

• Manufactured from high-grade polyethylene terephthalate polymers
• Exceptionally high tensile strength (800-1200MPa range)
• Available in multiple deniers and lengths for customized performance

Key Performance Benefits

• Crack control: Effectively mitigates both plastic and drying shrinkage cracks

• Impact resistance: Enhances toughness and energy absorption capacity

• Durability: Excellent resistance to alkalis and chemical attack in concrete environments

Optimal Application Scenarios

1. Thin-section concrete: Ideal for slabs, overlays and toppings

2. Shotcrete applications: Tunnel linings and slope stabilization

3. Industrial flooring: Warehouses and manufacturing facilities

4. Repair mortars: Structural rehabilitation projects

Technical Specifications
