Abstract: Espumas de melamina/formaldehído que contienen de 80 a 98% en peso de un material de carga inorgánico, refiriéndose el % en peso al peso total del precondensado de melamina/formaldehído usado para la fabricación de la espuma y al material de carga inorgánico, caracterizadas porque los materiales de carga inorgánicos tienen diámetros de partícula medios de 0,03 mm a 3 mm y se presentan en forma de partícula, encontrándose la relación del eje espacial más largo respecto al eje espacial más corto de la partícula en el intervalo de 4:1 a 1:1.
