Products classified under HTS 2921.22.05.00
Hexamethylenediamine Adipate (Nylon Salt)
Hexamethylenediamine adipate, commonly known as Nylon salt, is the salt formed from hexamethylenediamine and adipic acid, used as the direct precursor for producing Nylon 6,6 polymer. It falls under HTS 2921.22.0500 as a derivative salt of acyclic polyamine hexamethylenediamine. This chemically defined organic compound is supplied in pure form for industrial polymerization processes.
Nylon 6,6 Polymerization Salt
Industrial-grade hexamethylenediamine adipate used exclusively in the production of Nylon 6,6 via melt polymerization. This specific salt matches HTS 2921.22.0500 as it's the defined reaction product of hexamethylenediamine (acyclic polyamine) and adipic acid. Typically supplied as white crystalline powder with controlled moisture content.
AH Salt for Nylon Production
AH Salt (Adipic acid-Hexamethylenediamine salt) is the technical name for hexamethylenediamine adipate under HTS 2921.22.0500, serving as the monomer salt for high-performance Nylon 6,6 resins. This pure chemical intermediate enables direct salt melt polymerization without water removal steps. Used by major nylon producers worldwide.
Industrial Nylon Salt Flakes
Flaked form of hexamethylenediamine adipate (Nylon salt) optimized for continuous polymerization reactors, classified under HTS 2921.22.0500. The flake physical form facilitates uniform melting and reaction control in nylon production. Meets specifications for fiber-grade and engineering plastic-grade nylon 6,6.
Polymer-Grade Hexamethylenediamine Adipate
High-purity (>99.5%) hexamethylenediamine adipate meeting polymer-grade specifications for premium Nylon 6,6 used in automotive and aerospace applications. Precisely matches HTS 2921.22.0500 as the named acyclic polyamine salt derivative. Supplied with full analytical package including GC, HPLC, and Karl Fischer water content.
