The excellent results of the protections are reached with a special inside structure made of
different layers of foam. The front part is made of a special shock-absorber with slow memory,
able to absorb the first phase and speed of the impact, avoiding a severe impact for the athlete.
The other components of the protections are realized with different layers of foam with different
density and an open cell structure. This open cell structure is studied to guarantee the right
proportion between air volume and foam mass, mandatory for the correct cushioning and reduction
of speed of the colliding athlete.
The foams are specially chosen based on their compression factors and deformation, which at the
moment of the impact have to compress to a limited extent, evacuating the air across the appropriate
open air channels. Each single system has different inside structures which were especially studied
and tested to reach the highest possible impact force and bounce back reduction.
The internal part of the mat is made up of several kinds of foam, which have different thicknesses and
shapes. Viscoelastic foam and rebounded foam have a real efficacity. The viscoelastic low resilience foam
has been engineered and performed for the aerospace industry for the positioning of astronauts. With the
aim of obtaining the maximum distribution of the compression load in static and dynamic conditions. The
viscoelastic low resilience material is self-shaping: this property allows distributing the body weight
uniformly on the whole surface, avoiding some parts being overweighted. The viscoelastic foam comes back
to the original shape even after heavy and long term pression and assures a good shock absorbation. The
foam, with its completely open cells, assures an excellent speed of air escaping. An agglomeration is
by definition a compacted material, obtained from hot-pressed particles (granules) mixed with substances
that will in turn glue the elements. An agglomeration offers an optimum resistance to compression over
time, which is different from a normal foam. It has a compressed cellular structure instead of a free
structure. Therefore, not like a normal foam, the cells, being already compressed, suffer a minimally
negligible deformation with time.
A greater compression of the mix corresponds to an increased agglomeration
density and therefore the greater density corresponds to a better resistance to compression.
