    ※1:Functional examination resin:PBAT Mixing conditions:160℃

    ※2:Test method: GC-MS analysis of harmful gases generated by samples with 1wt% modifier added Resin: PBT Mixing condition: 250 ℃

    ※3:Temperature at 5% weight reduction Temperature rise condition: 5 ℃/min Our measured values

    The terminal product using C-768 will not produce odor.

    Due to the effective suppression of the gas generated during processing, it can be used with confiden.

  • Melt viscosity
    base resin:PBAT/PLA=7/3
  • No additives170~180℃
    C-768180~200℃
    Products from other companies170~180℃

    Adding C-768 has the effect of increasing viscosity.

    As shown in the table on the right, by increasing the processing temperature, C-768 can be processed under the same conditions as other company products.

    ※Can be used in conjunction with other company products.

  • Hydrolysis Resistance
