Barium sulphate BS70 for fiber

Barium Sulphate BS70for Fiber Barium sulfate BS70, specially developed for super bright polyesterfiber, is an ideal substitute of foreign barium sulfate for fiber, and has gotwidely recognizedby fibermanufacturersdue to itstop quality comparable with foreign products.Withspecial organic envelop treatment, the product has high whiteness, no impurities, uniform and narrow size distribution, excellent dispersion and no secondary cohesion. It can effectively disperse in polyester system, effectively improve the processing performance of polyester fiber, extend the filter usage time, reduce fiber breakage rate, increase fiber dyeability, spinnability and tensile strength, as well as make polyester chips and fiber reflect excellent optical performance.Applications: fiber polyester, color masterbatch.
