| Thermoplastic, low-smoke, halogen-free, flame retardant compound for cable insulation and sheathing. A flame-retardant low-smoke thermoplastic compound which has been specially developed to meet the requirements of limited toxic/corrosive fume emission, and having high fire retardance as indicated by a high oxygen index. TP543C has been specially developed to comply with the requirements of BS7655 Section 6 for types LTS1,2,3 and 4; EN 50290-2-27 for type HM2 and HD 604 for type HM4. Cables made with TP543C have complied with IEC 332 part 1 and 3 fire tests. TP543C is available in the following versions: TP543CN (natural colour) TP543CB (coloured black) TP543CNU (with a non-staining UV stabiliser added) TP543CBU (carbon black added to give UV&& |
