The Importance of Oxidative Stability In Polyolefins, Part 2
The DSC test can do a reasonably good job of capturing the comparative behavior of materials that use similar antioxidant chemistries.

MATERIALS: The Importance of Oxidative Stability in Polyolefins
Because oxidation is a process that causes materials to deteriorate over time, its effects or potential for those effects are not always apparent when new products are tested.

MATERIALS: The Problems with Single-Point Data
It’s time for material suppliers to take a fresh approach to providing data. Thankfully, things are starting to move in that direction. Part 12 of 12.

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.

MATERIALS: The Problems with Single-Point Data: Part 9
Time—and not just temperature—governs the behavior of materials under load. Both must be considered when evaluating a polymer for an application.

MATERIALS: The Problems with Single-Point Data, Part 8
DTUL tests may have made sense in the 1940s and 1950s, before the advent of dynamic mechanical analysis. But designers and engineers today need better tools.

MATERIALS: The Problems with Single-Point Data, Part 7
The industry can choose between continuing to perform DTUL tests that provide single points that are part of a curve never seen, or perform the test that provides the entire curve.
