Medium-impact modified nylon for fast, easy molding

Parts molded from 721 have good impact strength right out of the mold without post conditioning

Suitable for applications such as clips, fasteners, and other parts where some initial flexibility and impact resistance is desired

Cylinder temperatures should be in the 450°F-500°F range.
