This post is the first in a series that will cover the chemistry and curing of thermosets or thermosetting polymers.  This post will provide an introduction to the types and applications of thermosets.  The image on the left shows a filament wound container.  The individual fibers are impregnated with a thermosetting resin (typically epoxy) and then are wound around a ...

Thermosets (or thermosetting polymers) are an important class of polymeric materials.  The major use of thermosets is in applications where high temperature stability is required.  How do thermosets get this high temperature resistance?  One word: crosslinks.  Thermoplastics are high molecular weight linear (or sometimes branched) polymers.  They derive their useful properties ...

We are back after a short hiatus over the holidays and now will do a series of posts on thermosets or thermosetting polymers. Thermosets as a class of polymeric materials don’t get a lot of play per se.  When people think of polymers or plastics they typically identify the common plastics like polyethylene, polystyrene, and the ubiquitous polyethylene terephthalate (water ...

Time to take a break and spend time with family and friends.  We’ll be back the first week of January. ... [Click to Continue...]

Guest Post by Dr. Robert Humphreys Generation Y and Z may teach their grandchildren that replacing petroleum and coal by renewable energy, chemicals and polymers was a mission that defined the first 50 years of the New Millennium and distinguished “their time” from the fossil carbon dependence of previous generations. On the other hand, a cynical history professor might ... [Click to Continue...]
