Silane-modified LBR for next-gen EV tires
Kuraray
Kuraray announces the fusion of innovation and sustainability with its silane-modified liquid butadiene rubber (GS-L-BR), a new series of liquid rubbers tailored for the EV market’s accelerating growth. Kuraray’s silane-modified liquid butadiene rubber incorporates a reactive silane group that greatly enhances interaction with silica fillers and natural rubber (NR) in tires, which is crucial for EV applications. This synergy yields improvements in tire grip, rolling resistance and abrasion resistance, leading to an extended tire lifespan and superior driving dynamics.
With molecular weights from the thousands to a hundred thousand, Kuraray’s liquid rubbers, including isoprene, butadiene, styrene and an innovative bio-based farnesene, improve tire manufacturing processes and overall tire quality. The company’s latest research illustrates the benefits of silane-modified LBR in silica-enhanced rubber formulations, reinforcing their suitability for EV tires and underscoring improved fuel economy.
By combining GS-L-BR’s enhanced tire performance with Kuraray’s outstanding R&D capabilities, Kuraray is setting new standards for the EV tire industry, ensuring manufacturers meet the sector’s growing demands while committing to environmental excellence.
