As the raw material for tires, rubber compounds are comprised of various materials such as carbon black and silica.
The molecular structures and composition properties of these materials are complexly involved with each other and as tires generate performance. By developing “simulation”, “creation”, “control”, and “research” at the nano level (a nanometer = 1 billionth of a meter) of the materials making up these tires, we develop rubber materials with high precision.
That is Nano Balance Technology of TOYO TIRES.
TOYO TIRES establishes a graphing technology “Nano-level Tan Delta Simulation” that successfully lead to the master curve of energy loss (viscoelasticity) through the microscopic structure of rubber materials. With this industry-first technology, we can graphically quantify and evaluate the characteristics of rubber materials in the “low frequency region” showing Fuel Efficiency performance and “high frequency region” showing Wet Grip performance.
Design strong coupling polymers based on the result of the Nano-level Tan∂ Simulation.
Even if excellent raw materials were used, best performance cannot been obtained unless there is a processing technology that maximizes its performance. In Nano-level Production Control, precise mixing and temperate control of silica blending precisely controls the reaction between silica and coupling agent, which have made it possible to efficiently combine the polymer and silica.
By establishing 3D observation technology, pricise observation of the filler dispersibility in three-dimensional movement has become possible. It has been confirmed that the uniform dispersion control is possible with the latest compounds made by Nano Balance Technology.
Utilizing high- intensity X-ray facilities like SPring-8, one of the world's largest synchrotron radiation facilities, we established the industry-first X-ray observation technology of filler structure information under dynamic environments. In addition to the filler dispersibility, it is also possible to evaluate the reinforcement of rubber which leads to abrasion resistance and durability.
Through the evolution of Nano-level Analysis, we have established “Nano Dynamic Search” which performs three-dimensional observation of rubber material and analysis of rubber internal structure under dynamic environment. We observed rubber internal deformation during braking with high intensity X-ray and confirmed that rubber compound that designed based on molecular simulation has excellent friction coefficient as well.
