TECAMID® 66 natural
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.
