| abstract |
Highly temperable mixts. of olefin (co)polymers, elastomers or thermoplastic elastomers, which can be crosslinked by heating with peroxides, contain peroxides, (I), and/or other cpds. which generate radicals on heating and which are decomposed to 50% in 5 min. at 180 degrees C. The mixts. can be extruded on cables to form internal or external field-defining conductive layers. The mixts. can be processed continuously in extruders without the hazard of crosslinking during local overheating. Compsn. discharge temp. at extruder head can be 150 degrees C. Even extruder stoppages of >30 min at 135 degrees C, do not lower extrudate quality. |
