CASIDION is a revolutionary product for safety headwear designed to protect the head from the kinds of dangerous traumas caused by impact and shock. The technology is based on the most recent research into the dynamics of accidents and is designed to protect the most delicate and fundamental part of the human body, the brain. The scientific research that led to the development of CASIDION is based on the need to provide a solution that would go beyond the performance of all other materials commonly used for the production of protective headwear.



IMPROVED PROTECTION FROM REDUCED THICKNESS Helmets using CASIDION are lighter with reduced impact on the spine during normal use, at speed, and in falls.


The viscoelastic properties of CASIDION guarantee optimum helmet performance even in prolonged rolling with up to 7 impacts per second.


The CASIDION energy driver system provides 40% impact reduction. Impact energy is absorbed and diverted away from the head.


CASIDION guarantees maximum protection even in extreme temperatures ranging from -70°C to + 70°C.


The performance of safety equipment - above all helmets - should be assessed based on the effective protection they provide in real-world conditions. CASIDION has been designed with this in mind and performs to a higher standard than required by sector-specific norms.The chemical-physical structure of the CASIDION polymer has been designed to provide optimum performance even in the event of multiple impacts in falls where prolonged rolling occurs.

Expanded-Polystyrene is the best known and most widely used material for helmets. EPS is a lightweight expanded material which has no viscoelasticity. Its capacity to absorb impact is based on a collapsing of its internal cells and, as this is permanent, the section subjected to impact offers no further protection form any additional impact.

Expanded-Polypropylene is a lightweight expanded material with viscoelasticity and, within a limited temperature range, it may offer protection from multiple impacts. However at high temperatures the material becomes soft and at low temperatures it hardens which limits its possible application and use.

Other technologies and systems currently available on the market offer a compromise between performance and security. In general these do not offer multi-impact protection and many have problems in extreme temperatures or are excessively heavy or difficult to produce.
