In polymers, aging is commonly considered essentially synonymous with oxidation. But there are important differences between this type of chemical aging and less commonly recognized physical aging. Let’s unlock the mystery. ColumnsPublished: 10/23/2014
The huge chasm between the laboratory and manufacturing discipline usually does not lend itself to problem-solving. It can be improved with clear communication between the analysis laboratory and the people bringing the problem to the lab. ColumnsPublished: 9/22/2014
More than 50 different polymer test techniques can be used to find root causes of problems. Of these, five or six are fairly common. Use them to take the guesswork out of why a product failed.
Once degradation has been established, the discussion inevitably turns to how it happened. It might be expected that the answer to this question is widely known. Not so. The good news is that the influences that cause polymer degradation during proc... ColumnsPublished: 12/29/2013
There are two points in the manufacturing supply chain where a determination of average molecular weight (MW) is important. The first is when the material is first received by the molder. The second is after molding. ColumnsPublished: 11/26/2013
