Webinar – Thermal Analysis of Tires

"Thermal Analysis of Tires" Details the Main Thermoanalytical Techniques Used in the Tire Industry

A modern tire consists of tread and body; its constituents encompass synthetic rubber, natural rubber, fabric and wire, along with carbon black and other chemical compounds. The purpose of the tread is to provide traction, while the body contains compressed air and provides comfort. The investigation of tread and body samples, by thermal analysis allows the prediction of tire behavior and is important for compositional analysis and quality control.  

In this Webinar, we will show how thermal analysis is applied to investigate tire materials. We will present some typical examples of samples measured by DSC, TGA, TMA, or DMA.

In the webinar titled "Thermal Analysis of Tires", we describe a number of techniques and methods that can be used to characterize the physical properties of tire tread compounds.

Tire tread

The tread of the tire is in direct contact with the surface of the road. The tread formulation and the design of the tread pattern are therefore decisive factors for most tire properties such as low rolling resistance, good wet traction and high resistance to abrasion.

The ingredients of the tire tread have a significant impact on these properties. These are investigated using various thermal analysis techniques.


Thermal analysis of tires

The most important effects that can be analyzed by DSC are the melting point, melting range, and melting behavior. DSC is also used to determine the heat of fusion, the glass transition, and oxidative stability.

TGA measures weight changes. The main applications of TGA are content determination, thermal stability, decomposition kinetics, and compositional analysis.

DMA is used to determine the modulus and damping behavior of materials. It allows tire properties such as rolling resistance or grip behavior to be directly predicted.
