    Neodymium Finished Catalyst


    The Product : COMCAT Nd-FC

    Unlike current catalyst technologies, Comar can offer a Neodymium based liquid catalyst, that is a stable, finished catalyst, that is immediately highly active on its own, without requiring any further co-catalysts, in reacting butadiene monomers, to produce a high CIS, linear polymer, with narrow polydispersity.


    The Advantages

    • COMCAT Nd-FC is a highly active catalyst system, leading to a reduction in catalyst system cost, compared to conventional In-situ and Pre-form Nd catalyst systems
    • A polymer is produced with a very narrow molecular weight distribution
    • This polymer has better physical strength properties, such as higher Rebound
    • Lower solution viscosity is obtained, compared with conventional Nd-BR
    • The catalyst is stable in storage for 6 months or more, yielding exactly the same catalytic performance and the same polymer product, irrespective of storage time:



    Catalyst “Ageing” is not relevant any more

    COMCAT Nd-FC produces synthetic polybutadiene with improved physical properties, such as higher rebound. This makes this catalyst ideal in manufacturing synthetic rubber that leads to the lowest rolling resistance in car tires.
