Polyamide Material
Polyamide 66 has good
rigidity, hardness, abrasion resistance and thermal dimensional stability. In
addition, nylon 66 has outstanding wear resistance and low frictional
properties. It also has very good temperature, chemical, and impact properties.
Users should be aware of PA 66 propensity to absorb moisture which could affect
dimensional stability. In fact, PA 66 will tend to absorb more moisture at
saturation than cast PA type 6. It has been successfully used in diverse
applications ranging from electronics, marine, and automotive industries, to
forrestry, construction and mining.
