Technical Details & Test Data

Processing

SUPEROHM 4474 compounds are 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® 4474 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.
The following conditions are given as a guide for processing:

Temperature Profile:	°F	°C
screw	170	77
Zone 1 (feed):	210	99
Zone 2:	210	99
Zone 3:	210	99
Zone 4:	210	99
Head:	210	99
Die:	180	82

 

Packaging & Availability

Boxes

Packaging

• 1,750 pounds (794 Kg) per box.

Storage & Handling

Handling

• To ensure health and safety, Material Safety Data Sheets (MSDS) are available and should be consulted prior to use.

Storage

• SUPEROHM® 4474 containers should be stored at temperatures below 50°C (120°F) in a dry area to avoid massing of pellets. Product is recommended to be used within 12 months.
