Multiple layers of adhesive coated Kraft Paper strips are wound on the mandrel contineously to produce the paper tube and cores. Paper Tube formation need high tack and very quick setting properties. Yellow dextrin based adhesive formulations are generally used for this application. Complete lamination of Paper to paper is critical in achieving potential compression strength. Stardex offer Tapioca Dextrin based adhesive formulations for textile(POY /DTY) tubes and other heavy cores. Depending up on the application one can choose the solids between 33 % to 50%. The viscosity of the product is application dependent ( POY and DTY tubes need different viscosity) and can be maintained at constant level. |
