In addition, it can also be used to make health equipment, sporting goods, daily necessities, etc. Properties: PA66 polyamide 66 or nylon 66 chemical and physical properties PA66 has a high melting point in polyamide materials. It is a semi crystalline crystalline material. PA66 can also maintain strong strength and stiffness at higher temperatures. In product design, the influence of moisture absorption on geometric stability must be considered. In order to improve the mechanical properties of PA66, various modifiers are often added. Glass is a common additive. Sometimes synthetic rubber, such as EPDM and SBR, is added to improve impact resistance. The viscosity of PA66 is low, so its liquidity is very good (but not as good as PA6). This property can be used to process very thin components. Its viscosity is very sensitive to temperature changes. The shrinkage of PA66 is between 1% and 2%, and the addition of glass fiber additive can reduce the shrinkage to 0.2%~1%. The shrinkage rate differs greatly in the flow direction and the direction perpendicular to the flow direction. PA66 is resistant to many solvents, but weak to acids and other chlorinating agents. Features: 1. It has excellent wear resistance, self lubrication and high mechanical strength. But the water absorption is large, so the dimensional stability is poor 2 PA66 can also maintain strong strength and stiffness at higher temperatures. PA66 still has hygroscopicity after molding, and its degree mainly depends on material composition, wall thickness and environmental conditions. 3.
