It has excellent wear resistance, self-lubrication, and high mechanical strength. However, due to its high water absorption, its dimensional stability is poor2. PA66 can maintain strong strength and stiffness at higher temperatures. PA66 still has hygroscopicity after molding, and its degree mainly depends on the material composition, wall thickness, and environmental conditions.3. When designing products, it is important to consider the impact of moisture absorption on geometric stability. In order to improve the mechanical properties of PA66, various modifiers are often added. Glass is the most common additive, and sometimes synthetic rubber such as EPDM and SBR are added to improve impact resistance. PA66 has low viscosity, therefore it has good fluidity (but not as good as PA6). This property can be used to process very thin components. Its viscosity is very sensitive to temperature changes.4. The shrinkage rate of PA66 ranges from 1% to 2%, and adding glass fiber additives can reduce the shrinkage rate to 0.2% to 1%. The difference in shrinkage rate between the process direction and the direction perpendicular to the process direction is significant. PA66 has solubility resistance to many solvents, but has weak resistance to acids and other chlorinating agents.
