NIPPOLLAN N-963

1 of 6 products in this brand
NIPPOLLAN N-963 is newly developed polycarbonate diol (PCD) with added flexibility to the initial versions of NPU’s PCD (NIPPOLLAN 980, 981) products. NPU’s initial PCD products possessed high durability and stiffness due to its straight aliphatic carbonate chain structure, and have been widely applied in synthetic leather and various other applications. However, the lack of flexibility was one of its disadvantages. Therefore, a new series of PCD were developed which possessed the same durability but also with added flexibility property.

    Technical Details & Test Data

    Flexibility

    The following graphs show the improved flexibility of the new NIPPOLLANs by testing of modulus (M100-M300), elongation at break (EB) and reversibility properties using the formulation PCD/1.4BG/MDI (hard segment content approx. 32%).

    Safety & Health

    handling Precautions
    • Although the polycarbonate ester introduced here are generally considered stable chemicals, exposures to moisture followed by reaction with isocyanate may cause trouble. Therefore, it is advisable to store the product in airtight containers away from direct sunlight and kept below room temperature. In addition, avoid usage of product in humid places and ensure that equipment and tools used are dry.
    • Once opened, the container should be purged with nitrogen and resealed for future usage.
