Capillary Rheology of Thermoplastics: An Overview

Generally, capillary rheometers are used to measure melt properties at higher shear rates compared to rotational rheometers, allowing determination of flow behavior under typical processing conditions. Thermoplastics can be characterized using a Kinexus Rotational Rheometer, but also with the Rosand Capillary Rheometer.

How to Measure the Expansion of Materials Due to Water Uptake

NETZSCH_wood_humidity

In the previous articles, focusing on thermal analysis under humidity, we have seen that thermogravimetric analysis and dynamic mechanical analysis help determine the influence of water on a material or substance. Thermomechanical analysis complements the analysis under humidity.

Reduce Scrap Production with Thermal Analysis

NETZSCH_Reduce_Scrap2

Bringing cost, material, production process and quality successfully together is one of the key objectives in the injection molding industry. If the production process is not correct or if the material does not adhere to the specified requirements, low quality and thus scrap production is the consequence. Ideally, all of these four factors should be able to be managed in order to avoid scrap production. Thermal analysis methods offer valued approaches.

Why the Recycling Industry Benefits from the Use of Thermal Analysis

Plastics waste for reycling

Ever since plastics have become a popular material, manufactures have produced a total of 8.3 billion tons of virgin plastic. The production and usage of plastic has been a resounding success. However, it is alarming what is happening to the plastic that has served its time. The challenges posed by mechanical recycling can be overcome with thermal analysis.

Clever Tool for Short Cooling Times

How do nucleating agents influence the crystallization behavior of your polymer in the mold? To answer questions like these, the kinetics of the crystallization reaction is determined for mixtures of polypropylene with different nucleating agents. The results are used to carry out predictions on the product behavior for any temperature programs.
