Low-smoke, low-toxicity, halogen-free, flame-retardant, silane crosslinkable compound for insulation of LV cables and sheathing of all types of cables This is a flame-retardant chemically crosslinkable compound, curable by exposure to moist conditions and possessing good extrusion properties. The graft component SX407 is mixed with a crosslinking catalyst masterbatch CM424 generally in the ratio 95:5. The SX407:CM424 system has been specifically developed to meet the requirements of limited toxic/corrosive fume emission. Core or cable designs made using SX407 have complied with the following flame tests:- BS 4066 Part 1/IEC 332 Part 1; CEGB GDCD Standard 21; VDE 0472 Pt.804 Method C; VDE 0472 Pt.814; NF C 32-070 Test 2 (Category C1); BS 4066 Part 3; IEC 332 Part 3 (Categories A, B & C). A satisfactory cure can be obtained either by immersion in hot water or exposure to low pressure steam at a temperature up to 65°C. |
