Polyacrylonitrile Fibre

2.

Polyester fiberApplication- widely used in bituminous pavement and bridge construction, cold-patch and cementation of fissures of the road to protect the project from cracking.Features- it is heat-resistant in spite of features of good fineness, high-strength, easy to scatter, can be widely used in the project of bitulith to improve the nature of resistance to erosion and abrasion of the concrete.Physical parameter- type Sarciniform monofilament density 1.36~1.4g/cm3equivalent diameter 20±5 μm length 4,6,12mm (on request)strength of extension ≥500MPa shrinkage rate under high temperature ≥15%elongation at break ≥15% Acid & alkali-resist superiormelting point ≥250℃ Fire point Aprox 554℃
