Are You Ready for K 2016?
We’ve got you covered with five feature stories and an entire new-products section devoted to the October show in Dusseldorf.
MATERIALS:The Problems with Single-Point Data
This real-world scenario explains why molders and their customers need to ‘think in terms of graphs’ and gather as much data as possible before selecting a material for an application. Part 11.
MATERIALS: The Problems with Single-Point Data: Part 10
You can predict creep performance of a material over time at a particular temperature by examining how its modulus changes over a range of temperatures.
Melt Flow Rate Testing—Part 6
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...
Melt Flow Rate Testing–Part 1
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.
What's Different About Molding Engineering Plastics
If you try to run them like commodity materials such as PP you'll have problems.
Dimensional Stability After Molding: Part 4
In the first three parts of this series we focused on those influences that cause molded parts to get smaller. But there are environmental factors that also cause parts to increase in size over time.
Dimensional Stability after Molding—Part 3
Any process that involves melting and re-solidifying a polymer involves a compromise between achieving the perfect structure and producing a part that can be sold at a price that the market is willing to pay.
Dimensional Stability After Molding—Part 2
After molding, acetal parts can continue to shrink at room temperature and even in the cold.
Dimensional Stability After Molding: Part 1
The degree to which molded parts shrink as they cool is largely dependent upon the composition of the material being processed.
