Thermo Fisher Scientific offers a comprehensive range of material characterisation products that analyse and process material for rheological and thermal properties. These instruments are available from Rheology Solutions and they analyse and measure viscosity, elasticity, processability and temperature-related mechanical changes of plastics, foods, adhesives, coatings, and a wide variety of liquids or solids.
A brief overview of solutions across a number of industries for R&D, Process, and QC applications follows:
Rheological measurement data relating to dispersability and flow characteristics of ceramic injection moulding compounds and pastes provide the ceramics industry with valuable information to optimise products. To do this, a flexible, modular rheometer platform is needed to evaluate product processes used for manufacturing ceramics and suspensions for porcelain and/or ceramics.
Innovative recipe development, comprehensive reproduction simulation, and reliable quality assurance require a powerful rheometer platform in conjunction with pioneering measurement extruders and mixers.
Paints, dyes and powder coatings
Innovative paints and dyes demand extensive and precise rheological measurements. This begins with reliable quality control of raw materials and products and continues in the research and development of new formulations. Stability, time dependence, process characteristics when spraying or coating, and structural properties of these products must be derived in the early stages of development.
In the petrochemical industry simulation of pump characteristics and measurements for oils and drilling fluids under pressure is vital.
Pharmaceutical and cosmetics
Understanding the processability, consistency, time- and temperature dependent properties of raw materials and end products in order to develop innovative and successful products is critical.
Processing-related data such as melt characteristics, the effect of additives, temperature, shear stability and dynamic viscosity during shear are of great significance to the development of innovative polymers. Process simulation in compounding and extrusion of rods, profiles or films, combined with rheological or visual measurements, help the plastics industry to optimise procedural parameters, to create inspection bodies for tests or to perform quality checks at incoming and outgoing goods for viscosity, dispersion or plastifying characteristics.
The impact of carbon black on the cross-linking characteristics of a rubber compound and the dispersion or vulcanisation and flow properties of rubber are key to product quality. Furthermore, optimised end product mixing times are important not only to ensure efficient use of production plants, but also to successfully launch competitive products onto the market.
