Product Description
Type B semi-static ropes specially developed for rapid descent from helicopters by special forces. Their Aramid sheath does not melt, even against a descender overheated by the descent. Whereas classic ropes in polyamide or polyester have a very limited lifetime because their sheath melts, rendering the rope stiff and useless, Raider ropes permit multiple descents.
ROPES RESISTANT TO HIGH TEMPERATURES
EFFECT OF HIGH TEMPERATURES ON ARAMID
The resistance of Aramid to high temperatures is best illustrated by the graph illustrating the residual strength after exposure to raised temperatures. Thus we may for example see that after 10 hours of exposure at 200C it retains 100% of its strength, or that after 1 hour at 350C it retains 90% of its strength.
