TOKYO (Oct. 29, 2012)—By exploiting properties at nano scale—about 100 nm—Bridgestone Corp., together with development partners, has created a rubber material which delivers lower rolling resistance and better abrasion resistance.
The development is described in a Japanese-language document from NEDO, Japan's largest public R&D management organization. Bridgestone worked with NEDO and JSR Corp.
The development promises to improve rolling resistance by a further 20 percent ahead of today's state-of-the-art, represented by Japan's AAA tire label.
It also improves wear resistance by around 26 percent.
The material is based around an S-SBR with end-group modification, and with improved rubber-filler interaction.
Bridgestone said the breakthrough was achieved by independent control of the compound at three different scales: 1000 nm; 100 nm and 10 nm.
Bridgestone said it will implement the technology as soon as possible.
