Tire Technology
Virtual Conference

Tire Technology Expo provides a global platform for the international tire community to come together, and although the global health crisis has made organizing the annual live show impossible in 2021, the science of tire development, production and testing continues apace. 

Week 1: Tire Science, Research, Materials and Formulations
5 days: June 7, 8, 9, 10, 11, 2021

Week 2: Tire Manufacturing and Production
4 days: June 15, 16, 17, 18, 2021

Week 1:
NETZSCH-Gerätebau GmbH
"Simultaneous dynamic-mechanical and dielectric analysis of silica filled elastomer composites"

presented by Dr. Sahbi Aloui, Senior Application Engineer, NETZSCH-Gerätebau GmbH, Germany
on Monday, June 7, 2021 | 01:40 pm to 1:55 pm

Dynamic-mechanical and dielectric analysis are well-established techniques to describe the material behavior on the macro and nanoscale respectively.
Simultaneous combination of both techniques using the DiPLEXOR opens new opportunities to come closer to real applications during the operating phase by establishing the relationship between the macroscopic property change and the corresponding internal dynamics on the nanoscale. This represents the decisive criterion to understand why the samples are changing their properties during their service life.
What is the criterion of cost efficiency? And can the mechanical state be continuously monitored during application in order to avoid damage and/or wear?

Week 2:
Alpha Technologies
: "Determination of the critical  gel and optimization of vulcanization process"

presented by Michele Scacchi, Field Application Engineer, Alpha Technologies UK, Italy
on Tuesday, June 15, 2021 | 2:45 pm to 3:00 pm 

The blow-point transition of rubber compounds is investigated by rheological techniques during curing. Oscillatory shear experiments and cavity gap thickness determination are performed during isothermal curing. Rheological measurements reveal that the initial stages of cross-link formation produce a sol-gel transition. In this study we show that the formation of a polymer network at the critical gel point is strictly related to the thermal curing history independently of the type of rubber. We observed that times corresponding to the sol-gel transition at different temperatures are characterized by the same degree of curing and by the same die-gap variation.
