| Low-smoke, low-toxicity, halogen-free, flame-retardant, silane crosslinkable compound for low voltage insulation and sheathing of all types of cable This is a low smoke, low fume, fire retardant silane crosslinkable compound which can be processed as a thermoplastic at high output rates and cured post processing by exposure to moisture. The graft component SX559 is mixed with a crosslinking catalyst masterbatch CM540U generally in the ratio 97:3 to 95:5 The compound combines good mechanical, electrical and fire retardant properties to meet demanding insulation specifications including BS 7211. The compound can also be used for sheathing of cables requiring high fire retardance.&& |
