3. Applications

Purified 2,6-Naphthalene Dicarboxylic Acid (PNDA) is produced by the hydrolysis of dimethyl 2,6-naphthalene dicarboxylate (NDC). Polymers produced from PNDA exhibit properties suitable for use in:

  • High-performance polyester films
  • Fibers
  • Packaging applications
  • Engineering applications such as liquid crystal polymers (LCP)

4. Packaging & Storage

  • Packaging Options:
    • Bulk polypropylene fabric type ‘C’ bags (700 kg net weight, up to 2 bags per pallet).
    • Smaller packages available at additional cost.
  • Shipping & Handling:
    • No hazard warning required under OSHA criteria.
    • During unloading, the bags need to be properly grounded.
