Advanite™ PBT Solutions

SASA’s other base product is polybutylene terephthalate (PBT) polymer, PBT is a polymeric material formed by the interaction of dimethyl terephthalate (DMT) with 1,4 butane-diol (BDO),

PBT polymer products in SASA’s product portfolio are available for the following end uses:

    Injection (Production of all kinds of plastic materials)
    Industrial (Industrial applications requiring high tenacity, such as tire cord production)
    Medical (Parts of medical equipment and medical materials)
    Textile (Staple/filament fibers and  nonwoven production)

The target viscosity (IV) value in SASA’s PBT production technology is 0,90 dL/g, However it is possible to make amorphous production between 0,70 – 1,00 dL/g IV,  Additionally, it is possible to produce high IV products, such as 1,20dL/g IV with the existing SSP equipment,

SASA is capable of measuring the viscosity of PBT products by MVR (cm3/10min) in addition to IV,

PBT amorphous polymer is a naturally crystalline polymer, Therefore, there is no need for an additional crystallization process,  SASA can produce all of its products as crystalline or SSPed,

Titanium dioxide filling for textile end uses is also possible for PBT products, the same as for PET products,

Products are shipped in chips form by bulk containers or big bags,
