Abstract

ESTOPA DE ACETATO DE CELULOSE COM BAIXO DPF E BAIXO TEOR DE DIÓXIDO DE TITÂNIO. Trata-se de tiras de estopa de acetato de celulose que têm menos de 0,1% em peso de dióxido de titânio, em que o teor de dióxido de titânio é medido por calcinação e/ou por densidade de contagem de partículas de titânio. É também fornecido no presente documento um método para medir o teor de dióxido de titânio de estopa de acetato de celulose por calcinação. É também fornecido no presente documento um método para medir a cor da estopa de acetato de celulose.
