Product Application

Polyamides (Nylon, Core High-End Application):

Ultra-Long-Chain Polyamides:​ Polycondensation with hexamethylenediamine yields Nylon 614 (PA614), and with decamethylenediamine yields Nylon 1414 (PA1414). These nylons are top-tier products within the long-chain polyamide family, possessing extremely low water absorption, unparalleled dimensional stability, very high toughness, excellent wear/chemical resistance, outstanding electrical insulation, and hydrolysis resistance. Used in the most demanding applications, such as high-temperature/oil-resistant lines in automotive engines, high-pressure hydraulic hoses, aerospace components, deep-sea cables, precision electronic parts, and advanced sports equipment.

Synthetic Lubricants & Greases (Top-Tier Application):

Synthetic Ester Base Stocks:​ Complex esters formed with polyols (e.g., neopentyl glycol, trimethylolpropane, pentaerythritol) are premium Group V synthetic lubricant base oils. They feature very high viscosity index, extremely low pour point, exceptional thermal-oxidative stability, hydrolytic stability, and lubricity. Particularly suited for extreme and specialty conditions​ like aviation engine oils, ultra-low temperature instrument oils, high-speed/high-temperature bearing oils, and high-grade biodegradable lubricants.

Hot-Melt Adhesives:

High-Performance Polyamide Hot-Melts:​ Used in synthesizing ultra-high-performance polyamide hot-melt adhesives​ with higher heat resistance, excellent flexibility, strong bond strength, and superior fluid resistance. Applicable in demanding environments like automotive manufacturing (interiors, filters), premium footwear, and electronic encapsulation.

Powder Coating Polyester Resins:

Modifying Monomer:​ Used in producing super-weatherable, highly flexible polyester resins for powder coatings, significantly improving film impact resistance, overbake resistance, and durability.

Plasticizers:

High-Molecular-Weight Polyester Plasticizers:​ For manufacturing highly permanent polyester plasticizers with exceptional migration/extraction resistance, used in specialty wire & cable and medical devices.
