Technical Details & Test Data

Processing

Elastomers EPR 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 15/1 through 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.
The following conditions are given as a guide for processing (single extrusion):

Temperature Profile:	°F	°C
Screw:	170-180	77-82
Zone 1 (feed):	210-220	99-105
Zone 2:	210-220	99-105
Zone 3:	210-220	99-105
Zone 4:	210-220	99-105
Crosshead	220-230	105-110
