In our last post we talked about some of the common thermosets. Epoxy is a popular choice since it has good cost/performance, i.e. you can get a wide variety of interesting properties at a reasonable cost. Epoxies are characterized by the three member oxygen containing ring that is easily polymerized using a wide variety of nucleophiles (typically amines). There are many ... [Click to Continue...]
Thermoset Cure Chemistry 1: Introduction
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 ... [Click to Continue...]
Thermoset versus Thermoplastic Polymers
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 ...

Thermosets; An interesting subset in the polymer field
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 ... [Click to Continue...]
