Semi-dull boutique nylon 6 slices

Nylon 66 Material has a higher melting point among polyamide materials. Nylon 66 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 mainly 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 synthetic rubber is sometimes added to improve impact resistance. Nylon 66 tubing is less viscous and therefore flows better (but not as good as PA6). This property can be used to handle very thin components. Its viscosity is sensitive to temperature changes. The shrinkage of PA66 is between 1% and 2%. Adding glass fiber additives can reduce the shrinkage to 0.2%~1%. The shrinkage in the flow direction and perpendicular to the flow direction is quite different. Thermal Properties of Polyamide Nylon 66 Melting point is the temperature at which the crystals melt. For the crystalline polymer PA66 plastic, it shows a well-defined melting point. Depending on the test method used, the melting point fluctuates from 259 to 267°C. The melting point of PA66 plastic, usually measured by differential thermal analysis, is 264°C. The melting point temperature of nylon 66 is 246 to 263° C. when the temperature at which the volume expansion coefficient shows a maximum value is taken as the melting point. Close to the theoretical melting temperature of 259°C. Injection molding characteristics of PA66 plastic drying treatment: If the material is sealed before processing, drying is not required. However, if the storage container is open, drying in hot air at 85°C is recommended. If the humidity is greater than 0.2%, vacuum drying at 105°C for 12 hours is required.
