Low smoke, low-toxicity, halogen-free, flame-retardant compound for insulation of LV cables and sheathing of all types of cables

This is a low smoke, low fume, fire retardant silane crosslinkable compound, which can be processed like a thermoplastic material at high output rates. The crosslinking catalyst masterbatch CM601 is mixed with the SX-0612 graft component at an addition rate of between 5 and 10%, the rate dependent upon the extruder residence time.

The compound combines good mechanical, electrical and fire retardant properties to meet demanding insulation specifications such as BS7211 and IEC 60092-351/HF90. This compound can also be used for sheathing of cables which require high levels of fire retardance.

Crosslinking or Cure: A satisfactory cure can be obtained either by immersion in hot water or exposure to low pressure steam at a temperature up to 70°C. At the higher 10% addition levels of CM601 catalyst and under the correct conditions a satisfactory cure is possible at ambient temperature and humidity.

Extrusion instructions
Many modern thermoplastic extruders will process the material, although a screw designed to give good homogenisation without excessive shear (which could cause unacceptable increases in melt temperature) should be used. An extruder with an L/D ratio (length/diameter) of 15-24 and an extruder screw with a compression ratio 1.2:1 are recommended.
