TECAMID® 612

Low moisture nylon

Nylon generally has outstanding wear resistance and low frictional properties. It has very good temperature, chemical, and impact properties. However, nylon's primary weakness is a propensity to absorb moisture and thus have poor dimensional stability.  TECAMID 612 has lower moisture absorption rates than nylon 66, hence superior dimensional stability.
