LSZH Compound used in wires as per BS 7211/BS EN 50525-3-41 is Thermosetting Insulation suitable for the operating temperature of 90°C, Type EI5 to BS EN 50363-5.
PVC, when burnt, emits large quantities of dense black smoke and acid gas, and in addition to the debilitating effect of smoke and toxic fume inhalation, obscuration of fire safety exits delays or prevents escape. Improved PVC formulations producing less smoke and acid gas have been developed but still do not satisfy the required emission levels. The demand therefore has been for materials to replace PVC which do not give off smoke and toxic fumes and do not contain halogens.
The materials need to have the following characteristics:-
1 Fire retardant and zero halogen
2 Low emission of smoke, toxic fumes, and acid gases during combustion
3 Similar mechanical and electrical properties to PVC
4 Acceptable process-ability
5 Low additional cost
Detailed properties of the above material are
o Halogen Content – Max 0.5%
o pH value –Minimum 4.3
o Conductivity – Maximum 10 micro Siemens/mm
1. Conductor - Annealed plain copper (single-strand solid, class-1)
