09-14: Flame Retardance of Polymer Film Fills

While PVC is long known as a flame retardant polymer, other plastics have the reputation of high flammability. Whereas this is true for standard polyolefin materials, modern polypropylene products with high efficient flame retardant additives can even beat the good fire properties of normal PVC.In this study film fills for cooling towers made of PVC and of a flame retardant PP are tested by several different methods and international standards to evaluate the actual performance of these two materials.
