How Quality Control and Failure Analysis of PP Effectively Prevent Scrapping of Goods

by Jinyan Li, Liang Xu and Dr. Zhiqiang Zeng; NETZSCH Scientific Instruments Trading, China

Do you need a plastic part or a film with very specific properties – such as temperature stability coupled with dimensional stability accurate to a hundredth of a millimeter and UV resistance – otherwise it cannot be used for its intended purpose? But how can you check whether all requirements have been met and, in addition, how can failures be analyzed?
Only if such questions are under control is it possible to permanently reduce the number of rejects. NETZSCH Analyzing & Testing offers a range of thermoanalytical methods for this purpose.

NETZSCH EPS Standard Material for HFM Instruments: A Question of Reproducibility

When discussing the reproducibility of measurement results in general, what is known as the “reproducibility conditions” must always be taken into account. Measuring exactly the same specimen several times with exactly the same measuring device is usually not considered to be a reproducibility test, but a repeatability test. In order to draw conclusions about the … Read moreNETZSCH EPS Standard Material for HFM Instruments: A Question of Reproducibility

Sub-ambient DMA Measurements down to -70°C without Using LN2

Many investigations in the field of polymers with lower stiffness require a measurement start below room temperature. As an alternative to existing solutions with Vortex tube and liquid nitrogen cooling, NETZSCH now offers the new compact AIC 80 intracooler for DMA measurements that works with chilled air. It reliably cools samples to -70°C without the use of liquid nitrogen.

How to use TGA for the quality control of carbon fiber-reinforced polymers

CFRP_TGA_quality control_netzsch

The determination of fiber volume fraction is crucial for the quality control of carbon fiber-reinforced polymers (CFRP) in order to ensure their favorable mechanical and physical properties for the use in aerospace, wind energy and automotive sectors. A new thermogravimetric testing method, published by Dominik Grund in the journal “Polymer Testing”, considers heating rate, analysis atmosphere and sample size to efficiently ensure high quality of the material. This editorial summarizes the steps for the use of TGA in the quality control of carbon fiber-reinforced polymers.

Good Stability Versus Good Tabletability: The Choice of Modification

Many pharmaceutical solids exhibit polymorphism, i.e., the ability of a substance to exist in different crystalline forms. The polymorphic form can have significant influence on pharmaceutical processing and can, for example, affect grinding, granulation and tabletability. A DSC measurement allows for the characterization of the present modification. Here, different modifications of paracetamol are distinguished by means of DSC.
