Cetma - Magnum Plus

Cetma Magnum Plus 14.0 mm copper-colored power band. Extremely powerful power band! The price is per 10 centimeters. You choose the quantity you need, and we ship it in one continuous piece. Below you can read the full description in English.

The MAGNUM PLUS has been developed with a 4-layer structure:

1. The first very thin outer layer is an iridescent metallic copper coating that allows the rubber to change color, adapting to the surrounding environment.

2. The second black layer protects the inner natural latex from UV rays, preventing deterioration of the rubber band over time.

3. The third gray layer is made from a special high-modulus natural rubber to increase knot resistance.

4. The core layer is pure natural LATEX.

Thanks to the barrier layer, it is possible to use pure LATEX without additives. This feature allows our product to perform better than traditional rubber bands and helps maintain performance over time.

The external layer is made of latex with special additives that enhance the rubber band's reactivity and specific functions.

Additionally, these elastics have a much smaller internal hole diameter than traditional ones (only 0.9 mm), allowing more rubber volume within the same external diameter, resulting in greater power.

Their internal structure ensures consistent performance across different elongations, keeping the load steady up to 350% stretch.

The table below shows the developed force at various elongation levels. These data are useful for tuning your speargun, but we strongly recommend testing at 300% elongation—you’ll be amazed at how stable and powerful your speargun performs.
