TECAMID® 612

Low moisture nylon

product inquiry
request sample
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.
