Glossary Of Terms
amorphous polymer
A polymer having no crystallinity; for example, polysulfone. See Thermoplastics.

Aesno® is part of the nylon 12 family (polymers with 12 carbon atoms). Nylon 12 is tougher than nylon 11, with low density, good stress crack resistance, low water absorption and good dimensional stability. Tubing can be transparent or opaque. Amorphous grades offer more translucence. Very flexible grades also are available.
