Free Application Note

Much effort and expense is put into the accelerated weathering of plastics and for the purposes of optimizing stabilizer formulations, ranking performance, and meeting customer specifications.

An important consideration is that weatherability is not an inherent material property; it is a system property. Since pure polymers are rarely used in any real application, the entire system must be tested, and the evaluation must have predictive value.

This paper is a study by James E. Pickett, GE Global Research. It was originally published in Atlas SunSpots, Volume 35, Issue 73 in Spring 2005.

In 1999; GE initiated an effort to accurately predict the weathering of engineering thermoplastics based on aromatic polymers. In his study, Jim Pickett reports on the findings.
