Yokohama engineers recognised for plastic innerliner

ERJ staff report (DS)

Tokyo - The Yokohama Rubber Co., Ltd., has said two of its employees had received "Commendations for Science and Technology by the Japanese Ministry of Education, Culture, Sports, Science and Technology 2011" for their work on tyre inner liner technology.

With new material with the characteristics of rubber and resin, the technology makes possible an inner liner that substantially reduces air leakage from tyres, contributing to the improvement of vehicle fuel efficiency.

The two engineers named are Yuichi Hara, Manager, R&D Group No.2, R&D Dept., Research & Development Center

and Yoshiaki Hashimura, Manager, R&D Group No.3, R&D Dept., Research & Development Center

The inner liner developed by Yokohama Rubber uses a new material with a high level of balance between the low permeability of resin and the flexibility of rubber. The result is substantially reduced tyre leakage. In addition, the thickness of the liner is only one-fifth that of a conventional one, yet it can mitigate tyre leakage better, contributing to making the tyre lighter.
