Plastic recycling presents many challenges across the manufacturing workflow. One of the biggest challenges is controlling the uncertainty of feedstock quality. Variations in quality arise from mixtures of different polymer types in the recycling process. This is a step-by-step guide for the quality control of recycled plastics with the NETZSCH DSC 214 Polyma.
NETZSCH thermoanalytical instruments support the processes from incoming goods inspection to optimization of the manufacturing process to quality assurance of the final product. Visit the NETZSCH booth D49 in hall 11 to talk to the thermal analysis experts and listen to our series of short talks.

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.
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.
Spray-dried a-lactose monohydrate is a matrix of amorphous lactose in which lactose monohydrate crystals are embedded. Humidity has no influence on the crystal but amorphous lactose is very hygroscopic: in presence of humidity, it will transform into the crystalline form. This has consequences on the tableting properties of the substance. Thermal Analysis gives you first Information about the water content of your lactose and the consequences for its compressing properties.
The database system for thermal analysis by NETZSCH, called Identify, has now (from Proteus® analysis version 8.0 or higher) already more than 2000 database entries available.
Furthermore, Identify can now be used with combined TGA+DSC, TGA-c-DTA® and STA measurements, which allows for material identification with greater certainty.
AutoEvaluation by NETZSCH is a very helpful tool for evaluation of thermoanalytical measurements. The entire measurement is evaluated by AutoEvaluation automatically and autonomously (not via pre-defined macro!) – with only one mouse click – and just within a second. AutoEvaluation is available for DSC, TGA and now also for STA measurements. Furthermore, the adaptability of AutoEvaluation is adressed.
Drug excipient compatibility ensure that the efficacy of the active ingredient is not affected by the excipients. You get first information about compatibility and interaction of components with thermal analysis methods as DSC or TG.
Thermal stability of materials measured fast and easy with a thermobalance coupled to a FT-IR System. Here, this method is applied to determine the thermal stability of Eudragit® L100-55.
