Event Description

Radiation-modified Polyolefins to balance melt processability and application performance requirements

Electron beam processing of polyolefins and other materials has been available for many years. It is mainly thought of as a means of cross-linking polyethylene for wire & cable, tubing, shrink sleeves and molded parts. This program focuses primarily on non-crosslinked applications. This process has been used safely for many years and there is no residual radiation with electron beam modification.

The intent of this program is to encourage product and applications development engineers working in the plastics industry to consider utilizing radiation modification as a creative means for meeting challenging application performance requirements. Often, a particular polyolefin type that offers a desirable set of physical properties will be over looked because it has poor melt processability and cannot be converted into the final form such a film or foam. For instance, low-density polyethylene (LDPE) has excellent melt processability due to its branched structure but cannot be used because it does not meet the service temperature requirements of many applications. Linear Low-Density Polyethylene (LLDPE) on the other hand has excellent properties but poor processability due to its linear structure. Often, converters will blend LDPE with LLDPE to balance processability with properties but there are always serious trade-offs. By creating electron beam induced long chain branching in linear low density, the result is a polyolefins that behaves like low density but retains 100% of the desirable properties of linear low density polyethylene.

In this introductory presentation, Edward Phillips will discuss the fundamental concepts of radiation modification of polyolefins and describe its effects on melt processability. Subsequent discussion can delve more deeply into the processes that benefit from improved melt processability: Extrusion coating, thermoforming, blown films, foams.

This program will:

  • Provide a go-to source for putting together an experimental plan for determining the value of radiation modification in your process/application
  • Offer solutions not offered by the large material suppliers
  • Help the converter develop tailored solutions giving him a sustainable competitive advantage
  • Allow the converter to expand his portfolio of offerings with unique higher value radiation modified resins
  • Remove some of the mystery and misconceptions surrounding radiation modification (there's a lot more than cross-linking going on)
  • Shed light on the cost performance of radiation modified polyolefins

Who should attend

  • Materials and Process Engineers
  • Resins suppliers, compounders, converters and end users involved in extrusion based processing of polyolefins
