Between the inner and outer envelopes there is a stuffing of felt threaded with polymer fibre. The thickness of the stuffing is between 6-8mm, wt. of is 400-500 g/m2 and tension strength is 22.65 kg/f lengthwise and 21.10 kg/f in width direction. Flame resistance, to standard 07113 AFNOR, is 12.0 lengthwise and 16.5 in width direction. The change gives greater protection against missiles and fire compared with the original stuffing.</p> |
