Polyester Fiber

Polyester fiber is produced from modified polyester chips via blending, spinning, anti‑aging treatment, lipophilic surface treatment and chopping. Featuring high strength, high modulus, good heat resistance, thermal stability and fine compatibility with asphalt, it improves the tensile, shear, compressive and impact strength of asphalt concrete when added at 0.4% of the mixture. It endows asphalt pavement with high‑temperature stability, low‑temperature crack resistance, fatigue resistance, water stability, high skid resistance and low traffic noise, greatly upgrading pavement performance.
