Addressing Extrusion Problems with a New Generation of PPAs

Improve Extrusion Efficiency and Output Quality

Producers who manufacture extruded blown films and products like tubing, cable jacketing, and pipes typically encounter two main obstacles that impact product quality, production run rates, and yields: melt fracture and extrusion instabilities.

For years, manufacturers have added polymer processing aids (PPAs) to resins to reduce these common extrusion process problems. Using PPAs:

  • Achieves a smooth process throughput
  • Reduces die buildup and downtime
  • Facilitates a faster product changeover

the most common applications that benefit from PPAs

Because they offer a more consistent performance over a broader range of processing conditions, minimize discoloration caused by thermal breakdown, and reduce olfactory effects during processing and in final products, PPAs are used in applications blown film, extruded shapes, and fibers and monofilaments.

This white paper gives details about a new generation of PPAs which — even when used in smaller quantities than previous generation PPAs — improves extruder efficiency and product quality.
