| Thermoplastic, low smoke, halogen free, flame retardant compound for cable insulation and sheathing. This is a flame retardant, low smoke, thermoplastic compound which has been specially developed to meet the requirements of limited toxic and corrosive fume emission, having good moisture resistance and hot pressure performance. TP521 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 TP521 have passed the 3m³ smoke chamber test. TP521 is available in the following versions: TP521N (natural colour) TP521B (coloured black) TP521NU (with a non-staining UV stabiliser added) TP521BU (carbon black added to give UV stability)&& |
