An aerogel formed of silicone that has been infused with nitrogen is called nitrogen foam. It is perfect for insulating applications due to its extremely low thermal conductivity and moderate weight. In experiments, it was found to be effective at putting out fires and can also be used as a fire retardant. During maintenance and shutdown times, nitrogen foam has long been utilised widely on tanks, pipes, and process vessels. Any combustible vapours and oxygen are replaced by nitrogen by turning gaseous nitrogen into a high expansion foam and continually pumping it into the system.
Shock absorption foams are designed to provide exceptional protection in impact and shock-absorption applications. They are designed to show load-deflection arcs that are comparatively flat. Shock absorption foams are suitable for the cushioning and protection of various delicate parts and have the ability to absorb energy.
