Product Application

Polyamides (Nylon, Core High-End Application):

Long-Chain Polyamides:​ Polycondensation with hexamethylenediamine yields Nylon 612 (PA612), and with decamethylenediamine yields Nylon 1212 (PA1212). These nylons possess extremely low water absorption, excellent dimensional stability, high toughness, wear and chemical resistance, and good electrical properties. Widely used in automotive parts (fuel lines, air brake tubes), electronics/electrical components (connectors, coil bobbins), military, sports equipment, and premium brush filaments. PA612 and PA1212 are high-end products in the engineering plastics sector.

Hot-Melt Adhesives:

Polyamide Hot-Melts:​ A key raw material for manufacturing high-performance polyamide hot-melt adhesives. These adhesives offer excellent flexibility, heat resistance, chemical resistance, and bond strength, used in apparel interlinings, footwear, automotive interiors, and electronics assembly.

Synthetic Lubricants & Greases:

Synthetic Ester Base Stocks:​ Complex esters formed with polyols (e.g., neopentyl glycol, trimethylolpropane, pentaerythritol) are top-tier Group V synthetic lubricant base oils. They feature very high viscosity index, extremely low pour point, outstanding thermal-oxidative and hydrolytic stability, used in jet engine oils, high-temperature gas turbine oils, compressor oils, and refrigeration oils for extreme conditions.

Powder Coating Polyester Resins:

Modifying Monomer:​ Used in producing weatherable polyester resins for powder coatings, improving film flexibility, impact resistance, and overbake resistance.

Plasticizers:

High-Molecular-Weight Polyester Plasticizers:​ Used to produce highly permanent, migration/extraction-resistant polyester plasticizers​ for premium wire & cable and automotive interiors.

Fragrances:

Macrocyclic Musks:​ Can serve as a raw material for synthesizing certain macrocyclic musks (e.g., Musk T).
