Material Data Sheet
Material: Tecamid® ST (Nylon 6/6) Nylon
NylonTecamid® ST is Ensingers version of super tough nylon. It has increased impact resistance and toughness over Tecamid 6/6. Nylon was the first engineering resin. It has been used in applications ranging from electronic, marine, and automotive industries. Nylon has outstanding wear resistance and low frictional properties. It has very good temperature, chemical, and impact properties. However Nylon's one weakness is a propensity to absorb moisture and thus have poor dimensional stability.
