Nucleating Agent NA30

Product Overview

Nucleating Agent NA30 represents a advanced class of hydrazide-type additives engineered specifically for optimizing the crystallization behavior of aliphatic polyesters. Chemically known as Decanedioic acid 1,10-bis(2-benzoylhydrazide), this specialty chemical serves as a critical performance enhancer in polymer formulations. Our manufacturing process ensures high purity and consistent particle size distribution, making it an ideal choice for demanding applications in biodegradable plastics and food contact materials.

Working Mechanism

The efficacy of NA30 lies in its unique molecular structure which facilitates epitaxial crystallization. Upon incorporation into resin matrices such as Polylactic Acid (PLA), the agent dissolves at processing temperatures and subsequently crystallizes first during cooling. This early crystallization forms nanometer-scale filiform crystals that act as nucleation sites. These sites induce rapid heterogeneous nucleation in the surrounding polymer matrix, significantly reducing the overall crystallization half-time. The result is a finer crystal structure that improves both mechanical integrity and optical clarity without compromising the biodegradable nature of the substrate.

Key Performance Benefits

• Accelerated Cycle Times: Drastically shortens molding and processing cycles by promoting fast crystallization.
• Enhanced Mechanical Properties: Improves flexural modulus and thermal stability, allowing for higher heat deflection temperatures.
• Superior Optical Quality: Increases surface gloss and whiteness, essential for consumer packaging applications.
• Heavy Metal Deactivation: The hydrazide structure effectively chelates heavy metal ions, preventing catalytic degradation of the resin during processing.
• Food Contact Compliance: Suitable for use in indirect food packaging materials, meeting stringent safety regulations.

Technical Specifications

Industrial Applications

While primarily designed for PLA resins, Nucleating Agent NA30 demonstrates excellent compatibility with a range of biodegradable aliphatic polyesters including PHAs and PBS. It is widely utilized in the production of disposable cutlery, transparent packaging films, and rigid containers where clarity and heat resistance are paramount. The recommended dosage typically ranges from 0.5 to 1.5 parts per hundred parts of resin (phr). For optimal homogeneity, we advise using compatible dispersion agents during the compounding stage.

Storage and Handling

To maintain product integrity, containers should be kept tightly closed in a cool, dry environment away from direct sunlight and moisture. Proper storage ensures the free-flowing nature of the powder is preserved for extended periods. Our facility adheres to strict quality control protocols, providing Certificates of Analysis (COA) with every shipment to guarantee compliance with specified parameters.
