Crosslinking & Polymer Modification Rheology Control Electron Beam Rheology Control May 15, 2020 / May 15, 2020 by ebeam [embedyt] https://www.youtube.com/watch?v=tidr0p-yobs[/embedyt] Does your PE or PP resin have the exact material properties you want? If you’re manufacturing a specialty film, bottle, foam, or other plastic product, the standard off-the-shelf grades offered by the big resin manufacturers don’t always meet your needs. Read more »
Chain Scissioning Crosslinking & Polymer Modification Rheology Control What is the difference between crosslinking, branching, and chain scissioning? February 18, 2020 / September 19, 2025 by ebeam https://www.youtube.com/watch?v=UdiX3oW1sxM In the latest Crash Course, the E-BEAM team talks about the difference between three different types of polymer modification: crosslinking, branching, and chain scissioning.

Crosslinking & Polymer Modification E-Beam Long Chain Branching Rheology Control Long Chain Branching, Part 3 – Demonstrating Improved Drawability March 13, 2017 / June 2, 2021 by ebeam In Part 2, we irradiated three samples of LLDPE with the electron beam to impart long chain branching and we achieved the improvement in melt tension we were looking for. In Part 3, we irradiated one of the samples with a higher dose to produce LCB (long chain branched) LLDPE with a melt tension measurement […] Read more »
Crosslinking & Polymer Modification E-Beam Long Chain Branching Rheology Control Long Chain Branching, Part 2 – Experimental results March 10, 2017 / October 9, 2025 by ebeam Hypothesis: long chain branching of LLDPEs can improve melt strength in terms of drawability. We irradiated 3 LLDPE feedstocks with an electron beam and compared the properties of the 3 processed resins to a LDPE Control. The starting samples were: Radiation Processing We dosed the samples with a 150kW, 4.5 MeV electron beam accelerator. The […] Read more »
Chain Scissioning Crosslinking & Polymer Modification Long Chain Branching Rheology Control Long Chain Branching – Background. Part I November 9, 2016 / June 2, 2021 by ebeam This is the first of a three part series highlighting the advantages of long chain branching and crosslinking – – valuable modifications made by electron beam treatment. History Linear low density polyethylene (LLDPE) has been used in extrusion coating and blown film since the 1950s, where its excellent melt strength created new possibilities. Polypropylene (PP) […] Read more »

E-Beam Property Improvements Rheology Control 5 Common Questions About Rheology August 14, 2015 / May 15, 2020 by ebeam When you e-beam polyethylene resin pellets, won’t there be gels? This is often one of the first questions asked in regards to e-beam processing in relation to changing the rheology of polymers. The concern is that with the e-beam irradiation, crosslinking is occurring and therefore hard gels are being formed. However, at low doses, before crosslinking […] Read more »
Crosslinking & Polymer Modification Property Improvements Rheology Control What is chain branching? March 13, 2015 / October 15, 2025 by ebeam Crosslinking of polymers via electron beam irradiation (e-beam) is well known and the number of success stories involving it touch our daily lives in many ways – but more on that in a later blog. An important similar concept that might be a little less familiar to some is the process of chain branching. What […] Read more »

August 15, 2014 / July 24, 2020 by ebeam Let me tell you a story. In June of 2013, I was standing in our booth at the MD&M show in Philadelphia when I turned to face a stately looking gentleman holding some sort of medical device in his hand. He was shaking his head, saying “you sterilization guys have a history of horrible service.” […] Read more »
