The new MAGNUM SILVER elastic bands by CETMA COMPOSITES are made from materials of the highest quality and purity, as with the famous MAGNUM PLUS, now a benchmark for the freediving industry. In contrast to MAGNUM PLUS, the new MAGNUM SILVER have a less reactive behaviour, which is why they can be defined as intermediate elastics.
Here too, an inner rubber without additives is used so that the real properties of pure natural rubber can be experienced. In fact, all commercial rubber is made with various additives, e.g. anti-UV additives, which also change the mechanical performance of the rubber. In contrast, our rubber is pure but with a thin outer layer that is UV-blocking (black layer).
MAGNUM SILVERs guarantee the performance of natural rubber with a less explosive behaviour, which is why they are recommended for single (mono, double or triple elastic) or inverter-propelled crossbows.
They are designed and manufactured with a 4-layer structure:
1. the first layer, starting from the outside towards the inside, is an iridescent metallic silver-coloured layer that takes on the colour of the seabed, has the function of camouflage and protection of the elastic;
2. The second layer, black in colour, serves to protect the inner layers from ultraviolet rays so that the PURE NATURAL latex inside does not deteriorate over time.
3. The third layer, grey in colour, is made of higher modulus latex to increase the elastic’s resistance to binding.
4. The last layer, the inner one, is made of pure latex.
Thanks to the barrier layers we have inserted on the outside, pure latex can be used without any additives. This feature makes our product perform better than other traditional elastics and allows the elastic’s performance to be maintained over time.
The outer layers are, however, made of latex with special additives that not only serve their specific functions but also contribute to the elastic’s reactivity.
Their internal structure makes them very performant at different elongation factors, keeping the load constant with the elastic in tension even at elongations of up to 350%.
The table shows the forces developed for different elongation factors, this data is useful for setting up your speargun, but we strongly suggest you try it with a 300% elongation, already at this factor you will appreciate the enormous power and stability developed!!!
