ADINS® Fire Resistance

ADINS® is a proprietary and patented technology based on natural silicates that through surface modifications, provides new functionalities and reinforces properties in organic and inorganic materials. ADINS® Fire Retardancy technology offers a versatile product range of additives for polymers that act as synergists with Halogen and Halogen Free Flame Retardant systems.

They significantly improve the behavior of plastic components under fire conditions, enabling their compliance with the most stringent international health and safety regulations such as the European Construction Products Regulation (CPR) or the Railway EN45545. ADINS® synergists can be combined with the main polymeric systems, including thermoplastics and thermosets, boosting the performance of Halogen and Halogen Free Flame Retardants. Some of the ADINS® additives benefits under fire conditions are:

• Anti-dripping effect
• Reduction of the flame propagation
• Smoke suppression
• Reduction of the heat release
