Tire, MRG, Shoe Soles

Reinforcement

Americas, EMEA

In the deliberately simple webinar, an attempt is made to explain the reinforcement of rubber by active fillers. For this purpose, the amplification (reinforcement) effect is first illustrated by a tensile test. Subsequently, an attempt is made to demonstrate by means of a clear size comparison between filled material and a spaghetti plate on which size scales the amplification of force and elongation takes place at the molecular level. In order to measure the effect of reinforcement based on the morphology of the filler, the sizes of the SSA and DOA are briefly presented. Subsequently, it is explained why silica system, in contrast to the CB system, requires an adhesion promoter in order to leverage the full potential of this modern filler. Based on this, the success of the Silica/Silane system as the modern filler system in passenger car tires is explained. The advantages of the silica/silane system can of course also be used in all other rubber components, esp. in coloured MRG products or shoe soles. Finally, the knowledge gained is extended to the reinforcement of silicone rubbers.

Carrier

Worldwide

Did you ever hear about the “carrier effect” or absorbates being called “dry liquids”? If not, we at Evonik show you how highly absorptive SIPERNAT® specialty silica or AEROPERL® granulated fumed absorb liquids like a sponge and transform them into pourable powders. Learn how silica properties such as particle size influence the selection of the carrier. The right silica selection eases the handling challenges of highly viscous or sticky liquids and can be used when liquids need to be added to powder products which themselves don't have sufficient absorption capacity.

Tire

Evonik solutions for further improving PCR and TBR tire performance

Asia, China

in Chinese

New trends in tire development are to further improve the magic triangle and to increase the application of sustainable raw materials. The methods to adjust the low rolling resistance with a reinforcing filler is explained. Subsequently, Evonik solutions for further improving the performance of PCR and TBR tires as below will be discussed. ULTRASIL® 9100 GR and Si 363™ is a powerful Silica/Silane combination with improved balance between rolling resistance and abrasion resistance. ULTRASIL® 7800 GR is a HD silica for improved compound processing, improved dry handling and better abrasion resistance, especially for SUV and all season tires. ULTRASIL® 5000 GR allows higher silica loading with good compound processing and improved wet grip. A further improvement of winter properties is observed especially in ice traction for higher loading of ULTRASIL® 4000 GR compared to usual silica types with 105 – 120 phr loading. TBR tire rolling resistance is further reduced by higher replacement of carbon black with high specific surface area HD silica and silane.
