PA66 Polyamide 66 or Nylon 66 Chemical and physical properties PA66 has a higher melting point among polyamide materials. It is a semi-crystalline-crystalline material. PA66 also maintains strong strength and stiffness at higher temperatures. When designing products, it is important to consider the effect of hygroscopicity 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 rubbers such as EPDM and SBR are added to improve impact resistance. PA66 has a low viscosity and therefore 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. The shrinkage of PA66 is between 1% and 2%, and the addition of glass fiber additives can reduce the shrinkage to 0.2% to 1%. The difference in shrinkage in the process direction and the direction perpendicular to the process direction is large. PA66 is resistant to many solvents, but has weak resistance to acids and some other chlorinating agents.
