Crash Course Recap: Amorphous vs Crystalline Polymers

  Are you an organized traveler? Do you know how to pack your business pants to minimize creases? Or are you more likely to be throwing things in a bag at the last minute? And what in the world do these questions have to do with crosslinkable polymers?

Radiation Chemistry Rules: What is Glass Transition Temperature?

amorphous polymer structures

Electron beam crosslinking  can enhance different polymer properties such as tensile strength, impact strength, high-heat properties, abrasion and chemical resistance, and environmental stress crack resistance. But not all polymers crosslink. So how can you tell if your polymer is a good fit for e-beam crosslinking? One of the factors that help us know if a […]

Crash Course Recap: Crosslinkable Polymers

The last E-BEAM Crash Course tackled the subject of crosslinkable polymers. But just what are crosslinkable polymers? Ionizing radiation produced by the electron beam breaks bonds within the molecules of the polymers. With some polymers, these bonds reform in a beneficial way, which we call crosslinking. For example, polyethylene is a polymer that is relatively […]

Hydrogel Crosslinking

Although we may not recognize them for what they are, hydrogels are very useful and are becoming more and more common each day. We can find hydrogels in a wide variety of today’s products, from medical devices to contact lenses to your lunchtime Jell-O snackpack. So, what exactly is a hydrogel?

Increasing UHMWPE abrasion resistance with electron beam processing

Are you looking for a tough material with high abrasion resistance? The e-beam process can greatly improve the abrasion resistance of Ultra High Molecular Weight Polyethylene. Ultra High Molecular Weight Polyethylene is also known as UHMWPE. It’s pretty cool stuff. As the name implies, it is polyethylene with really long chains. In fact, it’s molecular weight […]

Throwback Thursday: Long-lasting barrier-resistant properties

With a show of hands, how many of you wear makeup on a daily basis? I myself never leave home (and actually rarely even walk around home by myself) without mascara and some form of gloss or lipstick. And in today’s world, a lot of us care a lot about what goes into our makeup. […]

Long Chain Branching, Part 3 – Demonstrating Improved Drawability

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 […]

Long Chain Branching, Part 2 – Experimental results

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 […]
