Contact Supplier Polyester fiber as the raw PET material is produced through adding some functional additive, by plastic melting, extruding, high-ratio stretching and special surface disposal.And shaped be cutting with special machine Its appearance is beam-like structure with many monofilament fiber collecting.
 Besides the small thinness, high tensile strength and easily scattering, polyester has outstanding temperature stability. In -40℃~220℃ temperature environment is not brittle, not deformation, maintain the existing strength. So it can be used in hot-mixing bitumen concrete projects and reinforced crack-resistance for high-tensile concrete.
