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.

Silicones’ role in decarbonization studied
A study to identify and quantify silicones’ contributions to the EU Green Deal’s ambitions to become climate neutral by 2050 reveals an annual greenhouse gas (GHG) emission saving potential of 96.4 metric tons (MT) in 2030. This is equivalent to the carbon footprint of 36 million people’s electricity consumption (for reference, Poland has 37 million inhabitants). These savings are projected to be 42.6 MT by 2050 for silicone-using technologies compared to non-silicones alternatives.
