eoregularity in the polymer main chain. Accordingly, polymers with low stereoregularity (atactic polymers) tend to be less valuable materials; for example, polypropylene can be a useful material only ...

For semi-crystalline polymers, the crystallinity rate is a key parameter which directly influences mechanical properties, such as mechanical resistance or stiffness, as well as thermal and gas barrier ...

This series of articles is designed to help molders understand how a few analytical tools can help diagnose a part failure problem. Michael Sepe is our analyst and author. He is the technical director ...

In a previous article we reviewed rapid forming of thermoplastic composites (TPC). In the second part of this three-part series, we’ll explore the thermal processes and how these can be managed, ...

Polyethylene (PE) is a semicrystalline polymer that is one of the most extensively manufactured polymers in the world for consumer products and packaging. Shopping bags, milk bottles, storage ...

But here’s the challenge: traditional QA/QC methods are often slow, hands-on, and destructive. They rely on solvent-based extraction or other time-consuming processes that are unable to keep up with ...
