Deduster removes fines, fluff, and streamers to improve PVC quality
Unwanted contaminants are no longer attracted to Sylvania Chemical's PVC pellets -- but customers are.
Sylvania Chemical Co. manufactures polyvinyl chloride [PVC] compounds at its plant in Denver, Pa. A few years ago, the company had problems with excess contaminants -- fines, fluff, and streamers -- in its flexible PVC compounds. These contaminants caused problems when Sylvania's customers processed the PVCs. The fines, fluff, and streamers burned first, creating specks and imperfections in the finished products. In addition, cross-contamination of colored fines caused color changes.
