Netzsch is offering a free webinar on rubber thermal analysis
Many objects encountered in day-to-day life are made of elastomers. Typical examples are car tires, hoses, seals, rubber gloves, cable sheathings and shoe soles. All these goods are made of loosely-crosslinked polymers with rubbery-elastic properties.
Thermal analysis is a powerful tool for characterizing elastomers in the context of research and development, quality control or process optimization. This group of analytical methods allows a wide range of information to be obtained about such points of interest as: the individual components of a rubber mixture; the varying thermal stability of a rubber seal under the influence of different gas atmospheres; the gases evolved during elastomer processing; the visco-elastic properties of a damping element under high frequency load.
In particular, TGA, DSC, high-force DMA, TMA, LFA and coupling techniques are widely used for the investigation of raw materials, semi-finished products and finished parts made of rubber.
This webinar gives an overview of the application spectrum of these methods using a range of selected examples and illustrates how glass transition temperatures, compositional aspects such as filler and plasticizer content levels, mechanical parameters such as modulus values, and the thermophysical properties (thermal diffusivity and thermal conductivity) can be determined.
