Cas no 26098-55-5 (Nylon 6/12)

Nylon 6/12 is a semicrystalline polyamide copolymer synthesized from hexamethylenediamine and a blend of adipic and dodecanedioic acids. It exhibits lower moisture absorption compared to Nylon 6 or 6/6, enhancing dimensional stability in humid environments. The material retains mechanical strength and rigidity while offering improved chemical resistance to oils, fuels, and hydraulic fluids. Its balanced properties include good abrasion resistance, thermal stability up to 120°C (248°F), and ease of processing via injection molding or extrusion. Common applications include automotive components, electrical connectors, and industrial parts requiring reduced water uptake. The 6/12 ratio optimizes cost-performance by balancing monomer content.
