Applications

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 aversely 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.
