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

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

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?

Good Stability Versus Good Tabletability

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.

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

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.

HFM 446 Lambda Series

The new HFM 446 Lambda Series features a standardized method for the measurement of thermal conductivity which is equally applicable in research and development and in quality assurance.

DSC 204 F1 Phoenix®

Con questo DSC (Calorimetro Differenziale a Scansione) all’avanguardia si possono ottenere elevatissime sensibilità e risoluzione. Inoltre si possono avere come accessori un autocampionatore (ASC), temperatura modulata (TM-DSC), ottimizzazione della line di base (BeFlat®), correzione delle resistenza termica e della costante di tempo (DSC-correction) accoppiamento a QMS e FTIR, estensione UV per foto-calorimetria.

DMA EPLEXOR® High-Temperature Series up to 500 N

The EPLEXOR® HT series by NETZSCH GABO is the only DMA/DMTA instrument line on market for measurements up to 1500°C.

DEA 288 Ionic - Analizzatore Dielettrico

Il design multifunzionale della DEA 288 Ionic permette di applicare diverse condizioni analitiche, ad esempio cicli di caldo e freddo, atmosfera a umidità controllata, luce UV. Questa flessibilità consente all’utente di determinare, in modo facile e opportuno, i parametri di processo del proprio materiale.
