Crosslinking vs Scissioning

When dealing with the electron beam processing of polymers, two terms you will often hear are crosslinking and scissioning. Although both of these things happen as a result of electron beam irradiation, they are two opposite processes. Both are used to enhance or reduce certain properties of polymers according to a company’s specific needs. Polymer […]

Crosslinked Foam and Its Application in the Automotive Industry

Did you know that electron beam processing is used to create crosslinked polyolefin foam? The extruded, unfoamed matrix is beamed at E-BEAM Services in an efficient reel-to-reel process. Later it can be foamed in a high heat process offsite. Crosslinked foam has increased heat stability, strength, and chemical resistance while retaining flexibility. These properties make […]

5 Common Questions About Rheology

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 […]

Molecular Structures in Polymer Crosslinking Chemistry

If crosslinking chemistry is like carpentry on a molecular level, then electron beam processing is like having a “secret weapon” in your tool belt. Instead of using time-consuming and complicated chemical crosslinking, let the electrons do the heavy lifting! When a polymer is showered with high energy electrons, the electrons kick off hydrogens and create […]

We put the “X” in PEX pipe

Polyethylene (PE) pipe goes through the e-beam process and becomes crosslinked (X). That is how we put the “X” in PEX. Polyethylene is the most common polymer we electron beam crosslink every day. We see it in different forms, from injection molded and thermoformed parts, extruded sheet, tubing and wire and cable. While there are […]

What is chain branching?

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 […]

Why use electron beam treatment curing for reinforced plastics or composites?

With the different curing options out there, how do you know which one is best for your product? UV curing is a good method for surface treatments, however UV has limited penetration. Thermal curing may provide the answer for some thicker materials, however e-beam curing has several advantages over the thermal curing process:
