Understanding Plastic Failures Due to Molecular Degradation

Plastic materials feature a unique balance of ductility and strength, both of which are associated with their inherent viscoelastic nature. However, they are susceptible to molecular degradation by a variety of exposures.

Molecular degradation is a permanent change in molecular weight that reduces the mechanical properties and integrity of the plastic material. Molecular degradation results in the premature failure of many plastic components, which results in substantial monetary costs. This process is not reversible.

This webinar by expert speaker Jeffrey A. Jansen will discuss how molecular degradation can occur during compounding, processing, storage or while in service, and how you can prevent it. You will come away with a better understanding of how molecular degradation takes place and its repercussions on the performance of the material.
