Abstract

"SEPARADOR DE BATERIA PRODUZIDO POR DERRETIMENTO A SOPRO E BATERIA". Separadores de bateria feitos de um entrançado uniforme, molhável, de fibras de derretimento por sopro. As fibras de derretimento por sopro são termicamente unidas umas às outras. Essas fibras são feitas de um material termoplástico. As fibras possuem um diâmetro na faixa de 0,1 a 13 micra (<109>) e comprimentos maiores que 12 milímetros (mm). O entrançado possui um peso base variando na faixa de a partir de 6 a 160 gramas por metro quadrado e espessura de menos de 75 micra (<109>), e um tamanho médio de poro de 0,3 a 50 micra (<109>).
