Abstract

"ESPUMA DE URETANO FLEXìVEL ALTAMENTE RESILIENTE E ESPUMAS MOLDADAS FLEXìVEIS COM BASE EM ISOCIANATOS MODIFICADOS COM ALOFANATO". Esta invenção refere-se a um processo para a preparação de uma espuma flexível. Este processo compreende reação de um poliisocianato modificado com alofanato, estável em estocagem, líquido, tendo um teor de grupos NCO de cerca de 20 a cerca de 42%, com um componente reativo com isocianato, na presença de um agente de sopro e pelo menos um catalisador, em que as quantidades relativas do poliisocianato e o componente reativo com isocianato são tais que o índice NCO é de cerca de 70 a cerca de 130.
