Polyamide 6, Polyamide 6.6 and Blends
Polyamide 6.6 and polyamide 6 and their blends are engineering thermoplastics characterised by high mechanical strength, stiffness and heat resistance. Even at low temperatures, polyamides have high toughness and are nevertheless easy to process.
Further advantages are the high wear resistance, advantageous slip properties and the good flow behaviour as well as the very good chemical resistance. The mechanical properties, such as strength and impact strength, can be further improved by reinforcement with glass or carbon fibres.
Polyamide 6 and Polyamide 6.6 – differences in Production
Polyamide 6.6 is produced by polycondensation of hexamethylenediamine (HMD) and adipic acid. Polyamide 6 is formed by polymerisation of caprolactam. Despite the different production methods, the mechanical and chemical properties of these two polyamides are very similar. There are slight differences in the melting point, water absorption, crystallinity and heat ageing. PA 6.6/6, a polymer blend of PA 6.6 and PA 6, combines the advantages of polyamide 6 and polyamide 6.6.
PA 6.6 – we Show You Alternatives
Bottlenecks in the supply chain for raw materials, above all ADN, have led to higher prices – a challenge for all those working with PA 6.6 compounds.
For some applications, however, good alternatives can be determined on the basis of the individual requirements for mechanics and heat resistance. Please ask for more information.

Application Areas of Polyamide
Due to their extraordinary properties, polyamides are almost indispensable in many areas of technology for components and machine elements, as high-quality electrical insulation materials and for many special applications. They include internal parts, housings, cable ducts, automotive fasteners, coils, household appliance panels, connectors, switches, panels and covers for electrical applications.
Since polyamides have a low own weight, do not corrode and nevertheless have very good mechanical properties, they can sometimes replace moulded metal parts.
K.D. Feddersen offers a comprehensive selection of high-quality polyamides. The basic range extends from non-reinforced grades to 60% glass-fibre-reinforced polyamide compounds.
