Neodymium Butadiene Rubber

Neodymium catalyzed polybutadienes are highly elastic polymers with a very high degree of resistance to dynamic stress, and retain these properties even at extremely low temperatures. ARLANXEO Nd-BRs have a very high 1,4-cis content together with a very low 1,2-vinyl content, a relatively narrow molecular weight distribution and a low degree of branching.


Key Properties  

Provided that the compounds are formulated and processed correctly, the vulcanizates have good resistance to aging, reversion, abrasion and flex cracking, good low temperature flexibility and high resilience.


Nd-BR’s micro- and macrostructure properties make them well suited for high performance tire treads in combination with higher performance sSBR to improve fuel economy and  tread wear as well as high performance golf balls requiring a high coefficient of restitution.   Nd-BRs can be blended with NR for goods having thick sections and requiring high resistance to reversion, e.g. buffers, roll covers needing high abrasion resistance, seals, profiles and other goods.

Main applications:

    · tires

    · conveyor belts

    · track pads

    · footwear soles

    · V-belts

    · golf balls
