Utilization of AI driven solutions for rubber compound formulation: A practical approach
The integration of artificial intelligence (AI) into various industrial sectors has spurred remarkable progress in the field of manufacturing process development. This concept has been extended to polymer compound formulations, where AI techniques have been used to optimize rubber formulations as well. Furthermore, it is conceivable that mixtures of other polymers, such as TPEs, thermoplastic materials or polyurethane compounds, could be similarly treated. Advantages of employing AI driven tools include reduced development time, enhanced efficiency and increased accuracy.

Custom compounding with Spherix aluminosilicate microspheres
Spherix manufactures post-industrial recycled aluminosilicate ceramic microspheres with a mean particle size of 3-4 μm. The solid, incompressible spheres mechanically facilitate ingredient dispersion, processing speed and improved surface quality within a wide variety of polymer systems during both mastication and downstream processing. They promote flow and can reduce the need for conventional lubricants depending on the compound. Spherix is a registered trademark of Spherix.

Therban HT: Compounding with a new heat resistant HNBR elastomer
There is an increased demand for elastomeric compositions having improved heat and fluid resistance in automotive and industrial applications. In automotive applications, new sophisticated designs and engineering of engine compartments and under-the-hood parts require the use of elastomeric composites that can withstand higher service temperatures and have excellent long term aging properties. Similarly, industrial applications are following a similar trend where elastomers are expected to have high performance and function longer in harsher conditions.

Silane modified low molecular weight liquid polymers in sulfur cured mixtures of styrene butadiene copolymers and silica
Global emissions of greenhouse gases from trucks and passenger cars are influenced by the deformation energy and friction losses of tires. It is mostly associated with the rolling resistance between the tire tread and the road surface. For this reason, the rolling resistance is considered one of the most important performance indicators (that is, targeted to be reduced) within the tire industry.

Low temperature properties of HNBR elastomers
Many methods exist to predict low temperature performance of
elastomers, such as the glass transition temperature (Tg) from
differential scanning calorimetry (DSC), dynamic mechanical
analysis (DMA), as well as lot temperature regraction, Gehman
torsional and compression set tests.
Effect of accelerator mixing ratio on curing characteristics of EPDM gasket materials
Due to the long service life of the washing machine, all polymer parts, especially rubber parts, need to have a service life of at least 10 years, which means excellent resistance to aging.
