I made a polyurethane foam by mixing a SOUFA solution into it. To be honest, this…it burns. It will extinguish itself in a short period of flame contact, but if you expose it to flame for a certain period of time, it will ignite. After that, it self-extinguishes before it is burned out.
Boric acid is an inorganic flame retardant. It is a material that is still in its infancy. We hope that each manufacturer will test it in various ways.
