    Neodymium Finished Catalysts


    The Product: COMCAT Nd-FC

    Unlike current catalyst technologies, Comar can offer a range of Pre-formed Neodymium based liquid catalyst, that are a stable, finished catalysts, that are immediately highly active on their 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 are highly active catalyst systems, 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 catalysts are stable in refrigerated storage for 12 months or more, yielding exactly the same catalytic performance and the same polymer product.



    COMCAT Nd-FC produces synthetic polybutadiene with improved physical properties. This makes this catalyst ideal in manufacturing synthetic rubber for radial car tires.



    • The products are supplied by seafreight by specialised T-14 or T-22 refrigerated Isotanks, that carry 16 mt at a time
    • Lower quantities are available on special request

      Typical Performance Data Sheet



    Currently the catalyst is available in a diluted form, containing polymerisation grade hexane in 16Mt T-14 or T-22 refrigerated Isotainers (Nd concentration: 0.06 mol/l).



    For laboratory tests:

    Quantities of 1 litre are available from sample forms (1 litre canisters).



    REACH registration for COMCAT Nd-FC has been obtained. Link to the certificate: 

    TSCA Registration has been obtained for the COMCAT Nd-FC catalysts in the USA.


    Technical Support

    Comar’s specialized technicians are able to assist synthetic rubber producers who wish to convert from outdated Ni- or Co- Ziegler Natta technology, to the advanced COMCAT Nd-FC system.

    This can include:

    1. Detailed recommendations and procedures for laboratory evaluations.
    2. On-site assistance in plant trials.
    3. Analytical backup to verify polymer properties.
    4. Assistance to modify your existing Polymerisation plant for the new Nd-FC catalyst technology.

    We invite you to make contact with us via our product enquiry form to discuss and explore this exciting new technology with you.
