SuperOhm® 3443

Superohm® 3443 is a UL listed 150°C stationary, 125°C flexible low smoke, non-halogenated, lead free flame retardant crosslinkable EPR insulation compound. It is formulated to obtain balanced performance characteristics with excellent electrical properties, outstanding ozone resistance, flexibility, thermal stability and flame retardancy. Superohm® 3443 is a colorable polymeric composition based on ethylene propylene rubber (EPR) containing peroxide curing agent. In a free flowing pellet form, this compound is ready for extrusion in a conventional CV extrusion line.

Technical Details & Test Data

Processing

SUPEROHM® 3443 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® 3443 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 20/40/20 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.
