What is nylon 66 material? Nylon 66 price

Chemical and physical properties of PA66 polyamide 66 or nylon 66 PA66 has a higher melting point in polyamide materials. It is a semi crystalline crystalline material.

Nylon 66 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 in Zui. Sometimes synthetic rubber, such as EPDM and SBR, is added to improve impact resistance.

The viscosity of nylon 66 is low, so the fluidity is good (but not as good as nylon 6). This property can be used to process very thin components. Its viscosity is very sensitive to temperature changes.

The shrinkage of nylon 66 is between 1% and 2%, and the addition of glass fiber additive can reduce the shrinkage to 0.2% and 1%. The shrinkage rate is different in the flow direction and the direction perpendicular to the flow direction. Nylon 66 is resistant to many solvents, but is less resistant to acids and other chlorinating agents.
