Polyester fiber

Application- 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.
