Neodymium Polybutadiene Rubber (NdBR)

NdBR is solution polybutadiene made with a neodymium catalyst. Cis-1,4 content is typically ≥97%, with a more linear chain structure than many Ni/Co BR grades. That combination gives very high resilience, excellent abrasion resistance, and low hysteresis.

Industry Applications

High-performance tire treads, sidewalls, and other dynamic rubber parts where rolling resistance, wear, and heat generation are critical. Conventional high-cis BR remains listed separately.
