Materials Know How
Why (and What) You Need to Dry
Other than polyolefins, almost every other polymer exhibits some level of polarity and therefore can absorb a certain amount of moisture from the atmosphere. Here’s a look at some of these materials, and what needs to be done to dry them.

We covered the invention of acrylic in our last installment. Here, we discuss its commercial development.

Though often criticized, MFR is a very good gauge of the relative average molecular weight of the polymer. Since molecular weight (MW) is the driving force behind performance in polymers, it turns out to be a very useful number.
Read MoreThe Effects of Temperature
The polymers we work with follow the same principles as the body: the hotter the environment becomes, the less performance we can expect.
Read MoreUnderstanding Strain-Rate Sensitivity In Polymers
Material behavior is fundamentally determined by the equivalence of time and temperature. But that principle tends to be lost on processors and designers. Here’s some guidance.

This so-called 'commodity' material is actually quite complex, making selecting the right type a challenge.

Aliphatic polyketone is a material that gets little attention but is similar in chemistry to nylons, polyesters and acetals.

The road from discovery in the lab to commercial viability can be long, and this was certainly the case for acetal polymers.
Read MoreTracing the History of Polymeric Materials: The Differences Between Nylons & Polyesters
In many respects, nylons and polyesters appear to be interchangeable. But there are interesting differences in the properties of these two families that arise from their chemical structures.
