Chemical and physical properties of PA66:

PA66 has a high melting point. It is a semi crystalline crystalline material. PA66 can maintain strong strength and stiffness even at higher temperatures. PA66 still has moisture absorption after molding, which mainly depends on the composition of the material, wall thickness, and environmental conditions. When designing a product, 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 a common additive, and sometimes synthetic rubber such as EPDM and SBR are added to improve impact resistance.
