Introduction of PA6/PA66: PA66 plastic has a higher melting point in polyamide materials. It is a semi-crystalline-crystalline material. PA66 also maintains strong strength and stiffness at higher temperatures. PA66 plastic remains hygroscopic after molding, the extent of which depends primarily on material composition, wall thickness, and environmental conditions. In product design, the effect of hygroscopicity on geometric stability must be considered. In order to improve the mechanical properties of PA66, various modifiers are often added. Glass is the most common additive, and sometimes synthetic rubber is added to improve impact resistance.
PA66 plastic is less viscous and therefore flows well (but not as good as PA6). This property can be used to process very thin components. Its viscosity is sensitive to temperature changes. The shrinkage rate of PA66 is between 1% and 2%. Adding glass fiber additives can reduce the shrinkage rate to 0.2% to 1%. The difference in shrinkage in the flow direction and the direction perpendicular to the flow direction is larger. 
Advantages of PA6/PA66
-
High Melting Point: PA6/PA66 materials have a relatively high melting point compared to other polyamide materials, making them suitable for applications requiring high temperature resistance.
-
Strength and Stiffness: Both PA6 and PA66 exhibit excellent strength and stiffness properties, especially at elevated temperatures, making them suitable for structural applications.
-
Hygroscopicity: PA6/PA66 materials have a degree of hygroscopicity, which can be advantageous in certain applications where moisture absorption is desired for specific properties.
-
Modifiability: PA6/PA66 can be easily modified with additives to enhance specific properties, such as impact resistance and dimensional stability.
-
Good Flowability: PA6/PA66 have lower viscosity compared to some other plastics, allowing for good flow during processing and enabling the production of complex and thin-walled components.
-
Reduced Shrinkage: By adding glass fiber additives, the shrinkage rate of PA6/PA66 can be reduced, improving dimensional stability in molded parts.
-
Wide Application Range: PA6/PA66 materials find widespread applications in various industries including automotive, electrical, consumer goods, and industrial components, showcasing their versatility and reliability.
