TECHNICAL DATA SHEET |
|
| General Description |
- 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.
