Tyres components curing

technology of electron beam treatment of tire components is constantly evolving and nowadays electron beam accelerators are installed and successfully operating in many tire manufacturing plants

 Early development of electron-beam treatment in tire industry accounted for the year 1975-1985. The first company to introduce the use of tire rubber components processed with a beam of accelerated electrons, was «Firestone tire and rubber company». Since that time, technology of electron beam treatment of tire components is constantly evolving and nowadays electron beam accelerators are installed and successfully operating in many tire manufacturing plants.

There are two major effects of e-beam treatment of tire components:

  • • Formation of C-C chemical bonds between the macromolecules — «crosslinking»;
  • • Formation of free radicals in the macromolecules of vulcanized rubber facilitates the formation of the grid with the sulfur bridges

Key results and benefits:

tyres irradiation effect1. Improving the performance of the tread:

    • • Improved wear resistance,
    • • Improved grip of the wheel,
    • • Lower hysteresis loss on rolling,
    • • Improved fatigue of rubber components (carcass, breaker),
    • • 5-10% higher tire life
 

2. Reducing the use of expensive additives to rubber compounds: antiagers and modifiers.

3. Reducing the share of expensive synthetic and natural rubbers:

    • • Lower use of the material, and so lower the mass of the tire
    • • The ability to use cheaper synthetic rubber

4.  Reducing defective goods and waste production
