Technical Details & Test Data
- Processing
SUPEROHM® 3728-5 compound is engineered to be processed on conventional extrusion equipment. Use of a L/D 15:1 to 24:1 extruder with a single flighted, general purpose, tapered screw for proper homogenization and fluxing of SUPEROHM® 3728-5 compound is recommended to obtain optimal output and properties. The compound supplied is in the cleanest state and is of the highest quality; however, the use of a breaker plate with a screen pack of approximately 20/40 or 20/60 mesh is recommended for optimal rheological flow and steady back pressure.
Pre-drying of the compound is not necessary, provided that the compound has been stored unopened in a cool, dry area.
