Bitumen Concrete Reinforced Fiber

 

1. Polyester fiber is a new-developed engineering material in recent years. With polyester as its raw material, the fiber is produced through adding some functional additive, by plastic melting, extruding, high-ratio stretching and special surface disposal. And shaped by cutting with special machine Its appearance is beam-like structure with many monofilament fiber collecting.

 

2. Besides the small thinness, high tensile strength and easily scattering, polyester has good heat-resistance. It can be used in hot-mixing bitumen concrete projects and reinforced crack-resistance for high-tensile concrete, so it is an ideal multi-functional reinforced material.

 

3. According to the testing report by  many authorized organizations, the polyester fibers main technological performance indexes all reach the advanced level of the same products in the world.

Usage: stuffing and packing of toy,pillow,sofa,seatcushion and leaning cushion; thermal insulation lining of shoes,gloves,cap and garment and so on;raw material of spray finishing cotton,gel-free cotton,hardening cotton and nonwovens; 
Also used in the bituminous concrete to reduce the stress concentration of the microcrack point , weakens or removes the tension caused by sun crack of the concrete or mortar, further prevents the happen and development of the microcrack.
