Linear, Low-Density Polyethylene (LLDPE) and High-Density Polyethylene (HDPE) Films
In addition to reduced melt fracture and die build-up, film processors will see dramatic improvements in processing with DuPont™ Viton® FreeFlow™ including: Lower operating costs, Increased output, Improved gauge control, cooling, Efficiency and physical properties, Increased melt strength, Improved bubble stability, Reduced need for blending.
New Metallocene Polyolefins
Metallocene resins can present processing problems. In research conducted by DuPont, resins with Viton® FreeFlow™ were processed with a 25ºC lower melt temperature with the same die pressure. This translates to higher melt strength, and faster cooling for optimal processing conditions.
Wire and Cable
During the manufacture of jacketing for wire and cable, die build-up can develop. The deposits on the die adversely affect production rates and surface quality. The use of Viton® FreeFlow™ reduces die build-up and improves processing and surface finish with no effect on electrical properties or permeability performance.
