The Effects of Time on Polymers
Last month we briefly discussed the influence of temperature on the mechanical properties of polymers and reviewed some of the structural considerations that govern these effects.

The Effects of Stress on Polymers
Previously we have discussed the effects of temperature and time on the long-term behavior of polymers. Now let's take a look at stress.

How Backpressure Optimization Affects Melt Preparation
Backpressure is often the least understood of the settings in an injection molding process, even though it can play a significant role in the final quality of the part. Let’s start with understanding what backpressure is and then learn how to optimize it for a given mold.

Tracing the History of Polymeric Materials, Part 27: Liquid-Crystal Polymers
Liquid-crystal polymers debuted in the mid-1980s, but the history of the chemistry associated with this class of materials actually starts a century earlier.
