Technical Details & Test Data
- Processing
SUPEROHM® 3749 compound is engineered to be processed on conventional extrusion equipment. It is recommended that this product is processed using a shallow screw, cross channel obstruction such as mixing rings should be avoided. Metering screw with 2.5-3:1 compression ratio in 20/1 extruders should produce satisfactory results. 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.
