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.
