Highly flexible, silane crosslinkable, low-smoke, low-toxicity, halogen-free compound for insulation and sheathing

A very flexible silane cross-linkable flame-retardant low-smoke halogen-free compound, which has been developed to meet the requirements of limited toxic and corrosive fume emission.

This compound is designed for use as both and insulation and sheathing in flexible cords used for appliances. It can also be used as a sheathing material for general power cable use here a combination of high flexibility and good hot deformation characteristics is required.

CM424 catalyst masterbatch is normally added at 5% to 95% of SX-0670 graft.

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 to 2:1 are recommended.
